ba92428514 intel: Make monotonic timer a first class citizen
The monotonic time now needs to be a first class citizen in Coreboot as

ab56b3b11c ChromeOS: Remove oprom_is_loaded

Implement this feature without dependency to CHROMEOS option

to gfx_get_init_done().

b32816e9a5 Remove PCI_ROM_RUN option
The main purpose of option rom is to supply int* handlers.
But supplying those is outside of coreboot scope and if someone needs those
they should run SeaBIOS anyway which runs the option roms wonderfully.

Running VGA oprom is kept because they're needed to init graphics.

This patch still keeps the options to include the option roms to make them
available to SeaBIOS.

3d299c4b09 lynxpoint me: add support for mbp clear wait in finalize step
The management engine is slow, requiring at least 500ms between
when the Dram Init Done message is sent (right after memory training)
to when the MBP will report that it is successfully cleared and
that the ME can finally be sent the EOP message.

Currently this is adding 100-150ms to the boot time.  If we defer
waiting for the MBP Clear indicator until the finalize step we
can gain back that lost time.

boot on falco with SMI debugging enabled to
ensure that the ME is locked down in the finalize step:

7c35131642 haswell: configure c-states
The c-states are configured according to the BWG, however the
package c-states are disabled as they currently cause platform
instability. The exposed ACPI c-state to processor c-state mapping
are as follows for ULT boards:
	ACPI(C1) = MWAIT(C1E)
	ACPI(C2) = MWAIT(C7S long latency)
	ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:
	ACPI(C1) = MWAIT(C1E)
	ACPI(C2) = MWAIT(C3)
	ACPI(C3) = MWAIT(C7S)

Included in this patch is removing the updating of current limit
registers as some of the MSRs are different and the proper values
are currently unknown. Lastly, some of the MSRs were renamed to
match the BWG.

Booted 3.8 kernel and used powertop to note package, core, and acpi
c-state residency.

3e4e303858 Unify coreboot table generation
coreboot tables are, unlike general system tables, a platform
independent concept. Hence, use the same code for coreboot table
generation on all platforms. lib/coreboot_tables.c is based
on the x86 version of the file, because some important fixes
were missed on the ARMv7 version lately.

0df4de9e96 haswell boards: support added chromeos function
The get_write_protect_state() function was added to the
chromeos API that needs to be supported by the boards.
Implement this support.

Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as
well by choosing the RO path.

c0cbd6e8c2 haswell: use dynamic cbmem
Convert the existing haswell code to support reloctable ramstage
to use dynamic cbmem. This patch always selects DYNAMIC_CBMEM as
this option is a hard requirement for relocatable ramstage.

Aside from converting a few new API calls, a cbmem_top()
implementation is added which is defined to be at the begining of the
TSEG region. Also, use the dynamic cbmem library for allocating a
stack in ram for romstage after CAR is torn down.

Utilizing dynamic cbmem does mean that the cmem field in the gnvs
chromeos acpi table is now 0. Also, the memconsole driver in the kernel
won't be able to find the memconsole because the cbmem structure
changed.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

467f31de92 haswell/lynxpoint: Use new PCH/PM helper functions
This makes use of the new functions from pmutil.c that take
care of the differences between -H and -LP chipsets.

It also adds support for the LynxPoint-LP GPE0 register block
and the SMI/SCI routing differences.

The FADT is updated to report the new 256 byte GPE0 block on
wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address
block so that part is zeroed to prevent IASL and the kernel
from complaining about a mismatch.

This was tested on WTM2.  Unfortunately I am still unable to get an
SCI delivered from the EC but I suspect that is due to a magic
command needed to put the EC in ACPI mode.  Instead I verified that
all of the power management and GPIO registers were set to expected
values.

I also tested transitions into S3 and S5 from both the kernel and
by pressing the power button at the developer mode screen and they
all function as expected.

a267161362 haswell: unify romstage logic
This commit pulls in all the common logic for romstage into
the Haswell cpu directory. The bits specific to the mainboard
still reside under their respective directories. The calling
sequence bounces from the cpu directory to mainboard then back
to the cpu directory. The reasoning is that Haswell systems use
cache-as-ram for backing memory in romstage. The stack is used to
allocate structures. However, now changes can be made to the
romstage for Haswell and apply to all boards.

3d0071bde3 haswell: adjust CAR usage
It was found that the Haswell reference code was smashing through the
stack into the reference code's heap implementation. The reason for this
is because our current CAR allocation is too small. Moreover there are
quite a few things to coordinate between 2 code bases to get correct.
This commit separates the CAR into 2 parts:
  1. MRC CAR usage.
  2. Coreboot CAR usage.
Pointers from one region can be passed between the 2 modules, but one
should not be able to affect the others as checking has been put into
place in both modules.

The CAR size has effectively been doubled from 0x20000 (128 KiB) to
0x40000 (256KiB). Not all of that increase was needed, but enforcing
a power of 2 size only utilizes 1 MTRR.

Old CAR layout with a single contiguous stack with the region starting
at CONFIG_DCACHE_RAM_BASE:

+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
|  MRC global variables                 |
|  CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+
|  ROM stage stack                      |
|                                       |
|                                       |
+---------------------------------------+
|  MRC Heap 30000 bytes                 |
+---------------------------------------+
|  ROM stage console                    |
|  CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
|  ROM stage CAR_GLOBAL variables       |
+---------------------------------------+ Offset 0

There was some hard coded offsets in the reference code wrapper to start
the heap past the console buffer. Even with this commit the console
can smash into the following region depending on what size
CONFIG_CONSOLE_CAR_BUFFER_SIZE is.

As noted above This change splits the CAR region into 2 parts starting
at CONFIG_DCACHE_RAM_BASE:

+---------------------------------------+
|  MRC Region                           |
|  CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
|  ROM stage stack                      |
|                                       |
|                                       |
+---------------------------------------+
|  ROM stage console                    |
|  CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
|  ROM stage CAR_GLOBAL variables       |
+---------------------------------------+ Offset 0

Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE,
which represents the expected stack usage for the romstage. A marker
is checked at the base of the stack to determine if either the stack
was smashed or the console encroached on the stack.

18af4d23f6 lynxpoint: Move a bit of generic RCBA into early_pch
Rather than have to repeat this bit in every mainboard.

Also, remove the reset of the RTC power status from here.
We had done this in TOT for current platforms but did not
carry it back to emeraldlake2 where this branched from.

If we clear the status here then we don't get an event
logged later which can be important for the devices that
do not have a CMOS battery.

239c2e843f haswell platforms: restructure romstage main
There was a mix of setup code sprinkled across the various components:
southbridge code in the northbridge, etc. This commit reorganizes the
code so that northbridge code doesn't initialize southbridge components.
Additionally, the calling dram initialization no longer calls out to ME
code. The main() function in the mainboard calls the necessary ME
functions before and after dram initialization.

The biggest change is the addition of an early_pch_init() function
which initializes the BARs, GPIOs, and RCBA configuration. It is also
responsible for reporting back to the caller if the board is being
woken up from S3. The one sequence difference is that the RCBA config
is performed before claling the reference code.

Lastly the rcba configuration was changed to be table driven so that
different board/configurations can use the same code. It should be
possible to have board/configuration specific gpio and rcba
configuration while reusing the romstage code.
