- Optionally override FSB clock detection in generic
LAPIC code with constant value.
- Override on AMD Model fxx, 10xxx, agesa CPUs with 200MHz
- compile LAPIC code for romstage, too
- Remove #include ".../apic_timer.c" in AMD based mainboards
- Remove custom udelay implementation from intel northbridges' romstages
Future work:
- remove the compile time special case
(requires some cpuid based switching)
- drop northbridge udelay implementations (i945, i5000) if
not required anymore (eg. can SMM use the LAPIC timer?)

The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

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.

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.

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.

Commit 2d42b340034ff005693482ef9ca34ce3e0f08371 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

STND: Set TDP Down from Nominal. This will limit CPU to

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

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

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.

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

- Separate Sandybridge from ChromeOS a bit
The Sandybridge code depends on chromeos features a whole lot.
As a first step, provide a code path to look up the MRC cache
without depending on u-boot.
- Move mrc cache handling to separate file
This enables us to handle the MRC cache from ramstage,
where we can write the flash safely (eg. to update the
cache).
Also teach it to lookup the current MRC cache from CBMEM,
as the original data block isn't available anymore.
After all the preparations, finally write to the SPI
as necessary. It's a simple round robin wear levelling
that erases the entire MRC cache region when it's full
and starts from the beginning.

It takes about 3 seconds to scrub 8GiB DDR266 RAM.
After ECC scrub XIP cache is disabled for system stability. There is
very little to do in romstage after ECC scrub, especially when RAM
debug messages are turned off. So the delay caused by this is hardly
noticeable.
Cache for complete ROM is re-enabled before ramstage is decompressed,
and it has no unstability issues. So the code required to re-enable
cache for ROM currently already exists in cache-as-ram_ht.inc.
A Kconfig option HW_SCRUBBER enables the scrub to be run on hard
reboots and power-ons.

Fix delay loop comments. Time waited and the comments did not match
in the origin (e7501), so delays currently "just work".
Move reset detection to main raminit and don't use generic
sdram_initialize for now, as there are local debug
functions I need to use. Fix AOpen respectively.
Disable ecc scrub, until I have it fixed for cache-as-ram use.

Use NORTHBRIDGE_INTEL_I945 to select the driver directory for build.
Use _SUBTYPE_945GC and _SUBTYPE_945GM to define at compile-time
which model of I945 the driver is built for.

Originally brought up by Sven Schnelle in March 2011
http://patchwork.coreboot.org/patch/2801/
http://www.coreboot.org/pipermail/coreboot/2011-March/064277.html
On some mainboards it may be neccessary to reset early during resume
from S3 if the SLFRCS register indicates that a memory channel is not
guaranteed to be in self-refresh.
On other mainboards, such as Lenovo X60 and T60, the check always
creates false positives, effectively making it impossible to resume.
The SLFRCS register is documented on page 197 of
Mobile Intel® 945 Express Chipset Family Datasheet
Document Number: 309219-006
which is publically available, and the register indicates if a memory
channel is guaranteed to be in self-refresh mode (if bit = 1), or that
a memory channel *may or may not be* in self-refresh mode (if bit = 0).
The register can thus only be used to positively learn that memory is
in self-refresh. It is not known for sure that memory is *not* in
self-refresh. The register is reset by the PWROK signal, which *should*
go low during S3, and go high again when resuming, so it is unsurprising
that SLFRCS has already been cleared when we read the register.
Sven's measurements of the CKE signal on a ThinkPad shows that memory
remains in self-refresh indefinitely, until coreboot re-initializes the
memory controller, even when SLFRCS bits were = 0.
Boards which require a warm reset when SLFRCS bits are cleared must now
explicitly enable the check in the mainboard Kconfig file.
This commit selects the new option in all existing i945 mainboards.
A follow-up commit will remove the option for ThinkPads.

Adapted from northbridge/intel/e7501 with only minor changes.
This commit provides minimal patch from e7501 and I prefer any
cosmetic clean-up to be done after initial merge.
Due the incomplete register specifications, it is safer to have
e7505 as a separate directory in case I improve it to support
wider range of memory configurations. I have no e7501 to test with.
