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

- 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

Cache for complete ROM is re-enabled before ramstage is decompressed,

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.

The current code works only with dual channel if Channel 0 uses SPD address
0x50/0x51, while the second channel has to use 0x52/0x53.
For hardware that uses other addresses (like the ThinkPad X60) this means we
get only one module running instead of both.
This patch adds a second parameter to sdram_initialize, which is an array with
2 * DIMM_SOCKETS members. It should contain the SPD addresses for every single
DIMM socket. If NULL is given as the second parameter, the code uses the old
addressing scheme.

the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

reduces the number of dependencies, so it's no longer extremely ugly to
specify them manually (see the src/pc80/Makefile.inc portion)
- Add double include guards around option_table.h defines
- Also, drop the AMD DBM690T work around for the issue

Resolves a number of TODOs items within, and clarified a number of other TODOs.
Change register_values[] from long to u8 (byte). For what we are doing
this is sufficient and makes it only 1/4 the size.
Remove a hard-coding of SDRAMC register that is redundant and now
incorrect, now that SDRAMC is conditioned on SDRAMPWR_4DIMM Kconfig
and set through register_values[].
This fixes all boards with 3 DIMM slots (e.g. ASUS P2B, A-Trend ATC-6220).
RPS registers are now set in runtime code; remove it from
register_values[] table.
Bring DUMPNORTH() back. The code it refers to is still there.
Move #define of NB up so the DUMPNORTH() macro can use it.

to remember updating manually. Converted this into HAVE_... properties, which
will be inherited automatically if someone copies a chipset to create a new
one.

- prevent GCC from inlining do_ram_command - it will break RAM initialization.
- fix the PCIRST# mechanism in those boards that do it, it requires 200ms, not
200us
- move PCIRST# as early as possible (before ich7_enable_lpc)

board porter: printk should always be available in CAR mode.
Also drop CONFIG_USE_INIT, it's only been selected on one ASROCK board
but it's not been used there. Very odd.
There is one usage of CONFIG_USE_INIT which was always off in
src/cpu/intel/car/cache_as_ram.inc and we have to figure out what to do with
those few lines.

struct from 1092 to 228 bytes.
