On ARMv7 the console code can also be built into
the bootblock. Currently building the ARM targets
on a reasonably fast machine can fail, because
console.bootblock.o is attempted to build before
build.h is created. This patch adds a specific
rule for the bootblock variant of console.c, to
match the other variants so that the race condition
goes away.

The romstage_handoff structure is intended to be a way for romstage and
ramstage to communicate with one another instead of using sideband
signals such as stuffing magic values in pci config or memory
scratch space. Initially this structure just contains a single region
that indicates to ramstage that it should reserve a memory region used
by the romstage. Ramstage looks for a romstage_handoff structure in cbmem
with an id of CBMEM_ID_ROMSTAGE_INFO. If found, it will honor reserving
the region defined in the romstage_handoff structure.

The current ramstage code contains uses of symbols that cause issues
when the ramstage is relocatable. There are 2 scenarios resolved by this
patch:
1. Absolute symbols that are actually sizes/limits. The symbols are
problematic when relocating a program because there is no way to
distinguish a symbol that shouldn't be relocated and one that can.
The only way to handle these symbols is to write a program to post
process the relocations and keep a whitelist of ones that shouldn't
be relocated. I don't believe that is a route that should be taken
so fix the users of these sizes/limits encoded as absolute symbols
to calculate the size at runtime or dereference a variable in memory
containing the size/limit.
2. Absoulte symbols that were relocated to a fixed address. These
absolute symbols are generated by assembly files to be placed at a
fixed location. Again, these symbols are problematic because one
can't distinguish a symbol that can't be relocated. The symbols
are again resolved at runtime to allow for proper relocation.
For the symbols defining a size either use 2 symbols and calculate the
difference or provide a variable in memory containing the size.

There is a need to calculate the proper placement for an rmodule
in memory. e.g. loading a compressed rmodule from flash into ram
can be an issue. Determining the placement is hard since the header
is not readable until it is decompressed so choosing the wrong location
may require a memmove() after decompression. This patch provides
a function to perform this calculation by finding region below a given
address while making an assumption on the size of the rmodule header..

Which takes a pointer to an EDID blob, and a size, and decodes it into
a machine-independent format in out, which may be used for driving

This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

This adds a new API for cache maintenance operations. The idea is
to be more explicit about operations that are going on so it's easier
to manage branch predictor, cache, and TLB cleans and invalidations.
Also, this adds some operations that were missing but required early
on, such as branch predictor invalidation. Instruction and sync
barriers were wrong earlier as well since the imported API assumed
we compield with -march=armv5 (which we don't) and was missing
wrappers for the native ARMv7 ISB/DSB/DMB instructions.
For now, this is a start and it gives us something we can easily use
in libpayload for doing things like cleaning and invalidating dcache
when doing DMA transfers.
TODO:
- Set cache policy explicitly before re-enabling. Right now it's left
at default.
- Finish deprecating old cache maintenance API.
- We do an extra icache/dcache flush when going from bootblock to
romstage.

SPI accesses can be slow depending on the setup and the access pattern.
The current SPI hardware setup to cache and prefetch. The alternative
cbfs_load_payload() function takes advantage of the caching in the CPU
because the ROM is cached as write protected as well as the SPI's
hardware's caching/prefetching implementation. The CPU will fetch
consecutive aligned cachelines which will hit the ROM as
cacheline-aligned addresses. Once the payload is mirrored into RAM the
segment loading can take place by reading RAM instead of ROM.
With the alternative cbfs_load_payload() the boot time on a baskingridge
board saves ~100ms. This savings is observed using cbmem.py after
performing warm reboots and looking at TS_SELFBOOT_JUMP (99) entries.
This is booting with a depthcharge payload whose payload file fits

In order to prepare the ramstage to be linked by the rmodule linker the
stack needs to be self-contained within the ramstage objects. The
reasoning is that the rmodule linker provides a way to define a heap,
but it doesn't currently have a region for the stack.
The downside to this is that memory footprint of the ramstage can change
when compared before this change. The size difference stems from the
link ordering of the objects as the stack is now defined within
c_start.S. The size fluctuation ranges from 0 to CONFIG_STACK_SIZE - 1
because of the previous behavior or aligning to CONFIG_STACK_SIZE. It
should be noted that such an alignment is unnecessary for 32-bit x86 as
the alignment requirement for the stacks are 4 byte alignment. Also the
memory footprint is still dominated by CONFIG_RAMTOP and CONFIG_RAMBASE.

Change:
This is the initial step for moving the AMD F15 & HUDSON1,2,3
SPD-read callout out of the mainboard directories and into
the wrapper. The next step is to update the platforms to use
this routine in BiosCallouts.c and to delete the code from the
mainboard directories. The DIMM addresses should be moved into
devicetree.cb.
If there are significant differences or reasons that the mainboard
needs to override this code, it's perfectly reasonable to keep using
the version in the mainboard, but this allows us to remove duplicated
code and simplify the mainboard directories.
Notes:
This started by duplicating what was in Dinar, and was changed to
use the devicetree.cb structures. Significant cleanup and magic
number reduction was done as well.
It is intended that this file will not be included in ramstage as
the DIMM init is all done in romstage.
This is similar to what was done for Parmer/Thatcher in commit
7fb692bd - http://review.coreboot.org/#/c/2190/
Fam15tn: Move SPD read from mainboards into wrapper
Yes, it would make sense to split this into two separate files
and move the SMBus initialization and access into the southbridge
wrapper. Maybe that can come next.

cbfstool usage change:
The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".
The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
# output: 0x44, which does not look like aligned to 0x40000.
To prevent confusion, it's now switched to "-P/--page-size".
Verified by building i386/axus/tc320 (with page limitation 0x40000):
cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
# output: 0x44

There should be a fixed 10ms wait after sending an INIT IPI. The
previous implementation was just waiting up to 10ms for the IPI to
complete the send. That is not correct. The 10ms is unconditional
according to the documentation. No ill effects were observed with the
previous behavior, but it's important to follow the documentation.

This patch parallelizes the AP startup for Haswell-based devices. It
does not touch the generic secondary startup code. Instead it provides
its own MP support matching up with the Haswell BWG. It seemed to be too
much trouble to support the old startup way and this new way. Because of
that parallel loading is the only thing supported.
A couple of things to note:
1. Micrcode needs to be loaded twice. Once before MTRR and caching is
enabled. And a second time after SMM relocation.
2. The sipi_vector is entirely self-contained. Once it is loaded and
written back to RAM the APs do not access memory outside of the
sipi_vector load location until a sync up in ramstage.
3. SMM relocation is kicked off by an IPI to self w/ SMI set as the
destination mode.
The following are timings from cbmem with dev mode disabled and recovery mode
enabled to boot directly into the kernel. This was done on the
baskingridge CRB with a 4-core 8-thread CPU and 2 DIMMs 1GiB each. The
kernel has console enabled on the serial port. Entry 70 is the device
initialization, and that is where the APs are brought up. With these two
examples it looks to shave off ~200 ms of boot time.

This patch only applies to CONFIG_MICROCODE_IN_CBFS. The intel microcode
update routine would always walk the CBFS for the microcode file. Then
it would loop through the whole file looking for a match then load the
microcode. This process was maintained for intel_update_microcode_from_cbfs(),
however 2 new functions were exported:
1. const void *intel_microcode_find(void)
2. void intel_microcode_load_unlocked(const void *microcode_patch)
The first locates a matching microcode while the second loads that
mircocode. These new functions can then be used to cache the found
microcode blob w/o having to re-walk the CBFS.
Booted baskingridge board to Linux and noted that all microcode
revisions match on all the CPUs.

Having this header file in the mainboard directory breaks

src/vendorcode/amd/cimx/sb700/OEM.h. The build probably works
fine on Linux systems because, due to case-sensitivity, Oem.h
will not match the #include "OEM.h" statement in
src/southbridge/amd/cimx/sb700/Platform.h.
The Oem.h file in the dinar mainboard is not used by any other

by defines in the correct OEM.h file. Therefore, the file can be
safely removed.

The save_mrc_data() was previously called conditionally
in the raminit code. The save_mrc_data() function was called
in the non-S3 wake paths. However, the common romstage_common()
code was checking cbmem initialization things on s3 wake. Between
the two callers cbmem_initialize() was being called twice in the
non-s3 wake paths. Moreover, saving of the mrc data was not allowed
when CONFIG_EARLY_CBMEM_INIT wasn't enabled.
Therefore, move the save_mrc_data() to romstage_common. It already has
the knowledge of the wake path. Also remove the CONFIG_EARLY_CBMEM_INIT
requirement from save_mrc_data() as well as the call to cbmem_initialize().

This commit pulls in all the common logic for romstage into
the Haswell cpu directory. The bits specific to the mainboard
still reside under their respective directories. The calling
sequence bounces from the cpu directory to mainboard then back
to the cpu directory. The reasoning is that Haswell systems use
cache-as-ram for backing memory in romstage. The stack is used to
allocate structures. However, now changes can be made to the
romstage for Haswell and apply to all boards.

It was found that the Haswell reference code was smashing through the
stack into the reference code's heap implementation. The reason for this
is because our current CAR allocation is too small. Moreover there are
quite a few things to coordinate between 2 code bases to get correct.
This commit separates the CAR into 2 parts:
1. MRC CAR usage.
2. Coreboot CAR usage.
Pointers from one region can be passed between the 2 modules, but one
should not be able to affect the others as checking has been put into
place in both modules.
The CAR size has effectively been doubled from 0x20000 (128 KiB) to
0x40000 (256KiB). Not all of that increase was needed, but enforcing
a power of 2 size only utilizes 1 MTRR.
Old CAR layout with a single contiguous stack with the region starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| MRC global variables |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+
| ROM stage stack |
| |
| |
+---------------------------------------+
| MRC Heap 30000 bytes |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
There was some hard coded offsets in the reference code wrapper to start
the heap past the console buffer. Even with this commit the console
can smash into the following region depending on what size
CONFIG_CONSOLE_CAR_BUFFER_SIZE is.
As noted above This change splits the CAR region into 2 parts starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+
| MRC Region |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| ROM stage stack |
| |
| |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE,
which represents the expected stack usage for the romstage. A marker
is checked at the base of the stack to determine if either the stack
was smashed or the console encroached on the stack.

In order to provide some wiggle room for changing the contents
of the rmodule header add some padding. This won't stop the need
for coordinating properly between the romstage loader that may be
in readonly flash and rmodule header fields. But it will provide
for a way to make certain assumptions about alignment of the
rmodule's program when the rmodule is compressed in the flash.

A rmodule is short for relocation module. Relocaiton modules are
standalone programs. These programs are linked at address 0 as a shared
object with a special linker script that maintains the relocation
entries for the object. These modules can then be embedded as a raw
binary (objcopy -O binary) to be loaded at any location desired.
Initially, the only arch support is for x86. All comments below apply to
x86 specific properties.
The intial user of this support would be for SMM handlers since those
handlers sometimes need to be located at a dynamic address (e.g. TSEG
region).
The relocation entries are currently Elf32_Rel. They are 8 bytes large,
and the entries are not necessarily in sorted order. An future
optimization would be to have a tool convert the unsorted relocations
into just sorted offsets. This would reduce the size of the blob
produced after being processed. Essentialy, 8 bytes per relocation meta
entry would reduce to 4 bytes.

The SMM handler resides in the TSEG region which is far above
CONFIG_RAM_TOP (which is the highest cacheable address) before
MTRRs are setup. This means that calling initialize_cpus() before
performing MTRR setup on the BSP means the SMM handler is copied
using uncacheable accesses.
Improve the SMM handler setup path by enabling performing MTRR setup on
for the BSP before the call to initialize_cpus(). In order to do this
the haswell_init() function was split into 2 paths: BSP & AP paths.
There is a cpu_common_init() that both call to perform similar
functionality. The BSP path in haswell_init() then starts the APs using
intel_cores_init(). The AP path in haswell_init() loads microcode and
sets up MTRRs.
This split will be leveraged for future support of bringing up APs in
parallel as well as adhering to the Haswell MP initialization
requirements.

code. The main() function in the mainboard calls the necessary ME
functions before and after dram initialization.
The biggest change is the addition of an early_pch_init() function
which initializes the BARs, GPIOs, and RCBA configuration. It is also
responsible for reporting back to the caller if the board is being
woken up from S3. The one sequence difference is that the RCBA config
is performed before claling the reference code.
Lastly the rcba configuration was changed to be table driven so that
different board/configurations can use the same code. It should be
possible to have board/configuration specific gpio and rcba
configuration while reusing the romstage code.

objcopy -B provides symbols of the form _binary_<name>_(start|end|size).
However, the _size variant is an absoult symbol. If one wants to
relocate the smi loading the _size symbol will be relocated which is
wrong since it is suppose to be a fixed size. There is no way to
distinguish symbols that shouldn't be relocated vs ones that can.
Instead use the _start and _end variants to determine the size.

The SMRR takes precedence over the MTRR entries. Therefore, if the TSEG
region is setup as cacheable through the MTTRs, accesses to the TSEG
region before SMM relocation are cached. This allows for the setup of
SMM relocation to be faster by caching accesses to the future TSEG
(SMRAM) memory.

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

The Link native graphics commit 49428d84 [1]
Add support for Google's Chromebook Pixel
was missing some of the higher level bits, and hence could not be
used. This is not new code -- it has been working since last
August -- so the effort now is to get it into the tree and structure
it in a way compatible with upstream coreboot.
1. Add options to src/device/Kconfig to enable native graphics.
2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.
While I realize that the product name is Pixel, the mainboard in the
coreboot tree is called Link, and that name is what we will use
in our commits.

This wasn't previously spotted because the printk's were correct.
However if one needed to get the value of the BDSM or BGSM register
the value would reflect the other register's value.

Currently the OS is free to use the memory located at the default
SMRAM space because it is not marked reserved in the e820. This can
lead to memory corruption on S3 resume because SMM setup doesn't save
this range before using it to relocate SMRAM.

The previous code w.r.t. resource allocation was getting lucky
based on the way fixed mmio resources on the system were being
chosen. Namely, PCIEXBAR was the lowest mmio space and the other
fixed non-standar BARs were above it. The resource allocator would
then start allocating standard BARs below that.
On top of that other resources were being added when
dev_ops->set_resources() was being called on the PCI domain. At that
point the PCI range limit were already picked for where to start
allocating from.
To ensure we no longer get lucky during resource allocation add the
fixed resources in the host bridge and add the memory controller
cacheable memory areas. With those resources added the range limit
for standard PCI BARs is chosen properly.
Depending on haswell board configurations we may need to adjust and
pass in the size of physical address space needed for PCI resources
to the reference code. For the time being the CRBs appear to be OK.
Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.

This commit updates the Lynx Point resource reservations before
the coreboot allocator assigns resources. There is no need to mark
anything as subtractive decode because there are no devices/buses
linked to the LPC device.
The I/O range reservations consists of claiming the first 4KiB
of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode
ranges are checked against the default claimed range. If those
ranges overlap or fall outside of the default range then those
resources are added.
The MMIO range reservations consist of claiming everything from
the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range
register are then conditionally added if they fall outside of
the default MMIO range.

The current code is attempting to convert from an invalid

will come from yet just return a static value.
This stops the kernel from going to S5 on boot because it
thinks the temperature is too high.
