Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.
Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

Fixing the location of the ram oops buffer can lead to certain
kernel and boot loaders being confused when there is a ram
reservation low in the address space. Alternatively provide
a mechanism to allocate the ram oops buffer in cbmem. As cbmem
is usually high in the address space it avoids low reservation
confusion.
The patch uncondtionally provides a GOOG9999 ACPI device with
a single memory resource describing the memory region used for
the ramoops region.
BUG=None

Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

This is based on the RCBA configuration setup from haswell.
It handles PCI, BARs, IO, MMIO, and baytrail-specific IOSF.
I did not extend it to handle MSR yet but that would be another
potential register type.
There are a number of approaches to this kind of thing, but in the
end they have a lot of switch statements and a mass of #defines.
I'm not particularly set on any of the details so comments welcome.

Divisor is a function of requested baudrate, platform-specific
reference clock and amount of oversampling done on the UART reference.
Calculate this parameter with divisor rounded to nearest integer.
When building without option_table or when there is no entry for
baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate.
For OxPCIe use of 4 MHz for reference was arbitrary giving correct
divisor for 115200 but somewhat inaccurate for lower baudrates.
Actual hardware is 62500000 with 16 times oversampling.
FIXME: Field for baudrate in lb_tables is still incorrect.

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.
To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

Be more conservative and only add VGA devices' prefetchable
resources as write-combining in the address space. Previously
all prefetchable memory was added as a write-combining memory
type. Some hardware incorrectly advertises its BAR as
prefetchable when it shouldn't be.
A new memranges_add_resources_filter() function is added
to provide additional filtering on device and resource.

Provide a common entry point for bringing up the APs
in parallel. This work is based off of the Haswell one
which can be moved over to this in the future. The APs
are brought up and have the BSP's MTRRs duplicated in
their own MTRRs. Additionally, Microcode is loaded before
enabling caching. However, the current microcode loading
support assumes Intel's mechanism.
The infrastructure provides a notion of a flight plan
for the BSP and APs. This allows for flexibility in the
order of operations for a given architecture/chip without
providing any specific policy. Therefore, the chipset
caller can provide the order that is required.

The sequence to inject microcode updates is virtually the same for all
Intel CPUs. The same function is used to inject the update in both CBFS
and hardcoded cases, and in both of these cases, the microcode resides in
the ROM. This should be a safe change across the board.
The function which loaded compiled-in microcode is also removed here in
order to prevent it from being used in the future.
The dummy terminators from microcode need to be removed if this change is
to work when generating microcode from several microcode_blob.c files, as
is the case for older socketed CPUs. Removal of dummy terminators is done
in a subsequent patch.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

This commit adds a new Kconfig option for the LynxPoint
southbridge that will have coreboot route all of the USB
ports to the XHCI controller in the finalize step (i.e.
after the bootloader) and disable the EHCI controller(s).
Additionally when doing this the XHCI USB3 ports need
to be put into an expected state on resume in order to make
the kernel state machine happy.
Part of this could also be done in depthcharge but there
are also some resume-time steps required so it makes sense
to keep it all together in coreboot.
This can theoretically save ~100mW at runtime.
Verify that the EHCI controller is not found in Linux and
that booting from USB still works.

... based on the EDID detailed timing values for
pixel_clock and link_clock.
Two undocumented registers 0x6f040 and 0x6f044 correspond to link_m and link_n
respectively. Other two undocumented registers 0x6f030 and 0x6f034 correspond
to data_m and data_n respectively.
Calculations are based on the intel_link_compute_m_n from linux kernel.
Currently, the value for 0x6f030 does not come up right with our calculations.
Hence, set to hard-coded value.

CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates
from a CBFS file is supported, however, the name implies that microcode is
present in CBFS. This has recently caused confusion both with contributions
from Google, as well as SAGE. Rename this option to
SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from
CBFS", and prevent further confusion.

Now that we have horizontal display areas that are not multiples of 32 bytes,
things are more complex. We add three struct members (x, y resolution and
bytes per line) which are to be filled in by the mainboard as it sets the mode.
In future, the EDID code may take a stab at initializing these but the values are
context-dependent.

walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.
Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.
Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

It was suggested to eliminate the lock for sprintf. One way to do it is
to make the fake tx_byte into a closure. This patch allows it.
It's a bit tricky since we need to preserve compatibility with romcc.

It is easy to adopt, scalable to design, reduces time-to-market, and

Now that there is a clearly defined boot state machine
we can add some useful post codes to indicate the current
point in the state machine by having it log a post code
before the execution of each state.
This removes the currently defined POST codes that were
used by hardwaremain in favor of a new contiguous range
that are defined for each boot state.
The reason for this is that the existing codes are mostly
used to indicate when something is done, which is confusing
for actual debug because POST code debugging relies on knowing
what is about to happen (to know what may be at fault) rather
than what has just finished.
One additonal change is added during device init step as this
step often does the bulk of the work, and frequently logs POST
codes itself. Therefore in order to keep better track of what
device is being initialized POST_BS_DEV_INIT is logged before
each device is initialized.

One of the most common hangs during coreboot execution
is during ramstage device init steps. Currently there
are a set of (somewhat misleading) post codes during this
phase which give some indication as to where execution
stopped, but it provides no information on what device
was actually being initialized at that point.
This uses the new CMOS "extra" log banks to store the
encoded device path of the device that is about to be
touched by coreboot. This way if the system hangs when
talking to the device there will be some indication where
to investigate next.

This can be used to indicate sub-state within a POST
code range which can assist in debugging BIOS hangs.
For example this can be used to indicate which device
is about to be initialized so if the system hangs
while talking to that device it can be identified.
