e8179b5138 Add ddr3lv_support flag to pei_data structure
This will enable DDR3 1.35V support for memory training in
the reference code.  It requires the board to be setup for
1.35V with whatever board-specific GPIOs are available.

48a4a7f244 Provide MRC with a console printing callback function
Let memory initialization code use the coreboot romstage console. This
simplifies the code and makes sure that all output is available in
/sys/firmware/log.

The pei_data structure is modified to allow passing the console output
function pointer. Romstage console_tx_byte() is used for this purpose.

ad67791382 Avoid using hardcoded values in MRC cache code
The MRC cache code, as implemented, in some cases uses configuration
settings for MRC cache region, and in some cases - the values read
from FMAP. These do not necessarily match, the code should use FMAP
across the board.

This change also refactors mrccache.c to limit number of iterations
through the cache area and number of fmap area searches.

a1ea82283d Make coreboot use the offset parameter in cbfstool create
On Sandybridge and Ivybridge systems the firmware image has to

- a firmware descriptor
- Intel Management Engine firmware
- MRC cache information
This option allows to limit the size of the CBFS portion in
the firmware image.

357bb2daf0 SandyBridge/IvyBridge: Use flash map to find MRC cache
Until now, the MRC cache position and size was hard coded in Kconfig.
However, on ChromeOS devices, it should be determined by reading the
FMAP.

This patch provides a minimalistic FMAP parser (libflashmap was too
complex and OS centered) to allow reading the in-ROM flash map and
look for sections.

This will also be needed on some partner devices where coreboot will
have to find the VPD in order to set up the device's mac address
correctly.

The MRC cache implementation demonstrates how to use the FMAP parser.

7f189cc74e Intel Sandybridge and UMA: use mmio_resource()
With SandyBridge northbridge code, uma_memory_size was reset to
zero before variable MTRRs were set. This means MTRR setup routine
did not previously create a un-cacheable hole for uma.

Keep the behaviour that way, mmio_resource() has a prerequisuite that
the new region does not overlap with any cacheable ram_resource().

The result is not optimal setup in the number of used MTRRs, but
continue with this approach until MTRR algorithm is improved.

6ff1d36a47 Intel and GFXUMA: fix MTRR and use uma_resource()
Commit 2d42b34003 changed the
variable MTRR setup and removed compensation of uma_memory_size in
the cacheable memory resources.

Since the cacheable region size was no longer divisible by a large
power of 2, like 256 MB, this caused excessive use of MTRRs.
As first symptoms, slow boot with grub and poor user response.

As a solution, register the actual top of low ram with ram_resource(),
and do not subtract the UMA/TSEG regions from it.

TSEG may require further work as the original did not appear exactly
right to begin with. To have UMA as un-cacheable, use uma_resource().

PSSS: method is added to assist in searching the _PSS
table for the appropriate entry that corresponds to the
desired max non-turbo ratio.

STND: Set TDP Down from Nominal.  This will limit CPU to
the TDP down configuration by sequencing the required
changes in the right order.

STDN: Set TDP Nominal from Down.  This will set the CPU
back to nominal configuration by sequencing the required
changes in the correct (reverse) order.

This does not introduce any functional changes and must
be paired with additional changes to be useful.

The current configured TDP can be checked to see that
the transition to/from a desired level is successful.

f4d362339f ELOG: Add support for a monotonic boot counter in CMOS
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.

fe7b5d2fa6 Ivybridge: fix workaround and enable PAIR
MCHBAR 0x5f10[7:0] should be set to 0x30 for ivybridge
and 0x20 for sandybridge.  Move this code to ramstage
and set it per-chipset.

Power Aware Interrupt Routing is supported in ivybridge,
enable it and set fixed priority.

Boot on ivybridge device and read MCHBAR 0x5f10:

mmio_read8 0xfed15f10
0x30

And verify PAIR is enabled (bit4=1):

mmio_read8 0xfed15418
0x24

77dbbac7e7 CPU: Add basic support for Nominal Configurable TDP
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
model_x06ax: frequency set to 1800

da83a5f18e Fixes to enable RC6 on IvyBridge
- 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
