It requires SMM TSEG and a _heap/_eheap region defined in the
linker script. The first time malloc is called in SMM the
start and end pointers to the heap region will be relocated
for the TSEG region.
Enable SPI flash and ELOG in SMM and successfully
allocate memory. The allocated addresses are verified
to be sure they are within the TSEG heap region:

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:
171 | 2012-06-23 16:02:55 | System boot | 285

In order to support SPI and ELOG drivers the SMM region
needs to be able to be larger than the previous allocation
below 0x7400. Now that we have support for 4M TSEG we do
not need to live in this region.
This change adds a 16KB heap region abofe the save state area
at TSEG+64KB and moves the C handler above this.
The heap region is then available for malloc and the C handler
can grow to support flash and event log features.
While updating the memory map comment in assembly stub I also
added a pause instruction to the cpu spin lock as this was
added to the C code in latest upstream rebase.

Ivybridge B0+ CPUs are capable of supporting multiple TDP levels.
This complicates the default case because now the registers that
were reporting max non-turbo ratio are reporting that value for
the highest possible TDP level.
For now this change just forces everything to use the Nominal TDP
values instead of the higher (or lower) levels.
- When building P-state tables, determine the P[1] (max non turbo)
ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after
they are written, which happens after BIOS_RESET_CPL is set.
- Set the current ratio to Nominal ratio at boot.
1) Verify that P-state table is generated properly with
P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12)
PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00
PSS: 1800MHz power 17000 control 0x1200 status 0x1200
2) Verify power limits in MCHBAR match PKG_POWER_LIMIT:
> rdmsr 0 0x610
0x800080aa00dc8088
> mmio_read32 0xfed159a4
0x000080aa
> mmio_read32 0xfed159a0
0x00dc8088
3) Verify turbo activation ratio is set to nominal ratio:
> rdmsr 0 0x64c
0x0000000000000012
4) Check that proper ratio was set at boot on one core only:
> grep 'frequency set to' /sys/firmware/log
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800

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.

The only difference in this code on all our platforms is the array
describing the GPIOs. Hence, only keep that array in the mainboard
ChromeOS directory and move everything else to generic ChromeOS ACPI
code.

When no valid MRC cache area is found, the mrc_cache data structure
was used without prior initialization. This sometimes caused a long
delay when booting because compute_ip_checksum would checksum up to
4GB of memory.

There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.
2. On the CPU on link, there is something about trying to set the lock
bit that is getting a GPF.
3. It's the wrong place and time to set it. Once controlled, they can't
be changed in the kernel. The kernel is what should control this
feature, not the BIOS, as we have learned time and time again. If
somebody is in as root and can start a VM, you have a lot more to
worry about than someone starting a guest virtual machine.

This check got in the code when some Linux distros shipped broken linkers
around 1999.
Since then, the code around that check was changed, and it does not make
sense anymore to have this check.

Brevity is the soul of wit, except for error messages;
then it's a sign of witlessness. I can say this because
this error message may be my fault, although it is lost
in the 20th century code base so who knows.
Anyway, when memalign dies, it's not a bad idea to have
a lot of information about what went wrong. So instead
of the terse single bit of "something failed" this patch
changes things to be a bit more useful.

- The unneeded poll on non-MT force-wake bit was timing out
and causing the gma_pm_init_pre_vbios() function to exit
early so it was not preparing PM registers properly.
I changed the gtt_poll() calls to not return on timeout
unless it can't proceed so we don't see half-initialized
registers.
- RC6+ (Deep Render Standby) is not working reliably so we
can just enable RC6 in the BIOS and let the kernel decide
if it wants to enable RC6+ later.
This Kernel message is new in kernel 3.4:
[drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

the timer has to be initialized on the according local APICs
or the system will just hang when udelay is used.
