We had only some MSR definitions in there, which are used in speedstep
related code. I think speedstep.h is the better and less confusing place
for these.

We only want to add data once per device. Using the one in
chip_operations is not very usable anyway, as different
devices under the same chip directory would need to output
entirely different sets of data.

This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.
Choices in Kconfig
- 1) Generate microcode from tree (default)
- 2) Include external microcode file
- 3) Do not put microcode in CBFS
The idea is to give the user full control over including non-free
blobs in the final ROM image.
MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:
cpu_microcode-y += microcode_file.c
MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.
These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
1) The rule is CPU-agnostic
2) Gives user more control over if and how to include microcode blobs
3) The rules for building the microcode binary are kept in
src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
which are already overloaded and very difficult to navigate.

Factor CPU allocation out of AMD northbridge codes. As CPU topology
information is required for generation of certain ACPI tables, make
this code globally available.
For AMDK8 and AMDFAM10 northbridge, there is a possible case of
BSP CPU with lapicid!=0. We do not want to leave the lapic 0 from
devicetree unused, so always use that node for BSP CPU.

The CPU can arbitrarily reorder calls to rdtsc, significantly
reducing the precision of timing using the CPUs time stamp counter.
Unfortunately the method of synchronizing rdtsc is different
on AMD and Intel CPUs. There is a generic method, using the cpuid
instruction, but that uses up a lot of registers, and is very slow.
Hence, use the correct lfence/mfence instructions (for CPUs that
we know support it)

Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.
If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:
void mainboard_post(u8 value)
{
switch(value){
case POST_TIME_TO_PARTY: some_fancy_lights();
break;
}
}
Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

If the CMOS is cleared or someone writes some random date/time
on purpose, the CMOS date register has a invalid date. This will
hurts some OS, like Windows 7, which hangs at MS logo forever.
When we detect that, we need to write a reasonable date in CMOS.
Alexandru Gagniuc:
Hmm, it would be interesting to use the date the coreboot image
was built and set that as the default date. At least until time
travel is invented.

Recent changes in EC/Vboot/U-boot have completely broken
the logging of developer and recovery modes.
Recovery mode may not be in VBNV, so if that is zero and
yet we are in recovery mode then assume it is there because
the button/key was pressed.
Since there may not be any actual developer mode switch
we look if option rom is loaded and the system is not
in recovery mode and consider that as developer mode.

The linux kernel contains an SMI driver that was written by
me (Duncan) and upstreamed a couple years ago called GSMI.
This driver will format a parameter buffer and pass pointers
to this parameter buffer to the SMI handler. It uses this to
generate events for kernel shutdown reasons: Clean, Panic, Oops,
etc.
This function expects to be passed pointers into the SMM state
save area that correspond to the prameter buffer and the return
code, which are typically EAX and EBX.
The format of the parameter buffer is defined in the kernel
driver so we implement the same interface here in order to be
compatible.
GSMI_CMD_HANDSHAKE: this is an early call that it does to try
and detect what kind of BIOS is running.
GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that
has event type and data. The kernel-specific events are
translated here and raw events are passed through as well which
allows any run-time event to be added for testing.
GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log.
First the gsmi driver must be enabled in the kernel with
CONFIG_GOOGLE_GSMI and then events can be added via sysfs
and events are automatically generated for various kernel
shutdown reasons.
These can be seen in the event log as the 'Kernel Event' type:
169 | 2012-06-23 15:03:04 | Kernl Event | Clean Shutdown
181 | 2012-06-23 16:26:32 | Kernl Event | Oops

This maintains a 32bit monotonically increasing boot counter
that is stored in CMOS and logged on every non-S3 boot when
the event log is initialized.
In CMOS the count is prefixed with a 16bit signature and
appended with a 16bit checksum.
This counter is incremented in sandybridge early_init which is
called by romstage. It is incremented early in order notice
when reboots happen after memory init.
The counter is then logged when ELOG is initialized and will
store the boot count as part of a 'System boot; event.
Reboot a few times and look for 'System boot' events in the
event log and check that they are increasing. Also verify
that the counter does NOT increase when resuming from S3.

This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.
It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.
A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.
The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.
ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign
And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions. This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.
This is a large commit and by itself it just provides a new
driver that is made available to coreboot. Without additional
patches it is not very useful, but the end result is an event
log that will contain entries like this:

Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.
Break the stack checking out into a separate function, which
we will later use for the APs.
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000
Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.
Syntax in devicetree.cb:
ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>
The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.
Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

The current code for initializing AP cpus has several shortcomings:
- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
there's more than one physical CPU, and CPUs are of different type
Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.

Intel Turbo Boost is a technology implemented by Intel in certain
versions of their Nehalem- and Sandy Bridge-based CPUs, including Core
i5 and Core i7 that enables the processor to run above its base
operating frequency via dynamic control of the CPU's "clock rate".
It is activated when the operating system requests the highest

We need to provide u-boot access to several different CBMEM
sections. To do that, a common coreboot table structure is used,
just different tags match different coreboot table sections.
Also, the code is added to export CBMEM console and MRC cache
addresses through the same mechanism.

The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.
There are some system limitations which need to be worked around
to achieve this goal:
- some console traffic is generated before DRAM is initialized,
leave alone CBMEM initialized.
- after the RAM based stage starts, a lot of traffic is generated
before CBMEM is initialized.
As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.
When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.
At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.
When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.
In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

This change adds 128K to the memory amount set aside for CBMEM in
case the CBMEM console is enabled (to keep the CBMEM 128K byte
aligned). The console buffer size is being set to 64K, which is
enough to accommodate the most verbose coreboot console and
u-boot console.

This patch adds code to initialize the time stamp collection
facility in coreboot. It adds a table in the CBMEM section, which
provides the base timer reading value (all other readings are
offsets of this one) and an array of timestamp id/timestamp value
pairs.
Just two values are being added now, this will have to be used
more extensively and also integrated into payloads to provide more
comprehensive boot process time measurements.
Also, since the CBMEM area could already contain a section (from the
previous run, before reset), when processing a section addition
request we should check if a section already exists and return its
address, if so.

We want to be able to share data between different phases of firmware
(rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate
location for this data, but normally it is not initialized
until coreboot reaches the ram stage.
This change initializes the CBMEM while still in rom stage in
case CONFIG_EARLY_CBMEM_INIT is set.
Note that there is a discrepancy in how coreboot determines the
size of DRAM at rom and ram stages, get_top_of_ram() is used at
rom stage and is not defined for all platforms. Those platforms
will have to define this function should they enable the
CONFIG_EARLY_CBMEM_INIT flag.

Packing a device tree into the coreboot table can easily make

there is no error handling in place to catch that case.
Increase the maximum memory usable for all tables from 64KB to

to 32KB.

appropriate):

* PCI ID in their header. If we encounter such an option rom, we need to do
* the mapping ourselfes
