This provides weak empty declaration for mainboard_ops.
The struct chip_operations is not defined for __PRE_RAM__ so
the declaration is also moved upwards in the output.

As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).
Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.
For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
- from CAR setup (no need to reserve the space)
- commented out code (that was commented out for years)
- only copy sizeof(sysinfo) into RAM after ram init, where
before it copied the whole GLOBAL_VAR area.
- from Kconfig

- 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

- drop northbridge udelay implementations (i945, i5000) if

When dropping ramstage.a, unused functions with unresolved

tim5690 compilation fail.
This fix makes sure we don't compile in the int15 handler code

c_start.o has a special case in the build system, which we can
eliminate, somewhat simplifying the build.
To ensure that the entry point is at the beginning, introduce a
new section .textfirst that is placed appropriately. In principle
the ENTRY() definition in the linker script should be enough, but
better be safe.

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.

ramstage.a has two issues:
1. duplicate source filenames don't survive the ar(1)
treatment properly (so files aren't considered)
2. ld doesn't resolve symbols if it isn't forced to, in
particular no overrides of weak symbols
Downside: The resulting binaries get slightly larger.
Link time optimizations should fix that, as would tighter
rules in the build system (to not compile unused code in
the first place).

This adds more configurability to POST codes. The current assumption
is that POST codes should be written to an IO port (e.g. LPC) if POST
codes are enabled. This changes the assumption so that POST codes can
be written to the serial console without being written to an IO port.
This enables POST codes by default using "default y" to avoid
changing current behavior.

- to access registers, use X86_$REGNAME now (eg. X86_EAX)

The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.
In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.

In hardwaremain() we can't add timestamps before we actually
reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged
in hardwaremain() when coming out of an S3 resume.
The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c

This change allows us to figure out how much of the AP stacks we are
using, as well as to catch any case of an AP overrunning its stack.
Also, the stack is poisoned, which is a good way to catch programming
errors -- code should never count on auto variables being zerod.
The stack bases are recorded in a new array, stacks. At the end,
when all APs are initialized, the stacks are walked and the
lowest level of the stack that is reached is printed.
Build and boot and look for output like this:
CPU1: stack allocated from 00148000 to 00148ff4:\
lowest stack address was 00148c4c
CPU2: stack allocated from 00147000 to 00147ff4:\
lowest stack address was 00147c4c
CPU3: stack allocated from 00146000 to 00146ff4:\
lowest stack address was 00146c4c
Note that we used only about 1K of stack, even though in this
case we allocated 4K (and in the main branch, we allocate 32K!)

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.

in the resume case, timestamps were collected in RAM stage
but not stored in CBMEM. This leads to only a single time stamp
covering 200ms being available for all of ram stage.

coreboot uses about 2K of stack on the BSP, and about 1K of stack on the
APs. No reason to use an overdimensonal stack of 32k per core/thread.

This is a basic romstage driver that can be used for the
MRC cache code on systems where we do not have the MRC cache
stored in a flash region that is memory mapped.
It uses the hardware sequencing interface to avoid having
to know anything about the flash chip itself.
BUG=chrome-os-partner:15031

that attempted to read the MRC cache at offset 0x3e0000.

If the event log is stored in flash that is not memory
mapped then it must use the SPI controller to read from
the flash device instead of relying on memory accesses.
In addition a new CBMEM ID is added to keep an resident
copy of the ELOG around if needed. The use of CBMEM for
this is guarded by a new CONFIG_ELOG_CBMEM config option.
This CBMEM buffer is created and filled late in the process
when the SMBIOS table is being created because CBMEM is
not functional when ELOG is first initialized.
The downside to using CBMEM is that events added via the
SMI handler at runtime are not reflected in the CBMEM copy
because I don't want to let the SMM handler write to memory
outside the TSEG region.
In reality the only time we add runtime events is at kernel
shutdown so the impact is limited.
Test:
1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event
log is operational and SMBIOS points to address in CBMEM.
The test should involve at least on reboot to ensure that the
kernel is able to write events as well.

- Fix handling of 5-byte Fast Read command in the ICH SPI
driver. This fix is ported from the U-boot driver.
- Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by
defining a name for the bool in Kconfig and removing the
forced select in southbridge config
- Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers
to use #if instead of #ifdef
- Relocate flash functions in SMM so they are usable.
This really only needs to happen for read function pointer
since it uses a global function rather than a static one from
the chip, but it is good to ensure the rest are set up
correctly as well.

Applied function attribute to function definition to avoid 'conflicting type' warning.
Function declaration is in src/include/cpu.h
void secondary_cpu_init(unsigned int cpu_index)__attribute__((regparm(0)));
But function definition in lapic_cpu_init.c is missing the "__attribute__" part.

The Intel PCH can override the ASPM settings via the MPC2 register.
Add a chip override for F0-F7. Mainboards may implement this as
needed.
This also fixes the final PM setup being done too early. It was
being done prior to the PCIe ASPM setup, which happens in the
bridge scan.

Right now the SPI bus is getting set to 20mhz for transactions
initiated with the software sequence interface.
In order to be able to do reasonable fastread/write/erase we
can bump this up to a higher value at boot before it gets
locked at 20mhz.
To do this read out the speed set in the SPI descriptor for
hardware sequencing and apply it to software sequencing.
