Having same memory region set as both WRPROT and WRBACK
using MTRRs is undefined behaviour. This could happen if
we allow DCACHE_RAM_BASE to be located within CBFS in SPI
flash memory and XIP romstage is at the same location.
As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.
There are no reasons to have this as board-specific setting.

Currently only there is only one eaglelake board in coreboot
(ga-g41m-es2l) featuring a G41 variant northbridge.
Adding boards with a different variant (Q43, Q45, G43, G45, B43) will
require this change for graphic initialisation.

This is a follow-on patch to commit 10141c30 -
(nb/intel/gm45: Use LAPIC udelay instead of custom version)
which removed the custom udelay from everywhere except SMM.
This patch removes it from SMM as well, and gets rid of the
gm45/delay.c file.

Instead of hardcoding pci_mmio_size in the raminit code,
this makes it a parameter in the devicetree.
A safe minimum of 768M is also defined since using anything
less causes problems (if 4G of ram is used).

Don't use scratchpad registers when we have romstage_handoff

late in ramstage so acpi_is_wakeup_s3() did not evaluate

This fixes low memory corruption at 0x1000-0x102c and the lack
of coreboot tables (util/cbmem not working) after S3 resume.
This also fixes console log from reporting early in ramstage

Fix-up for 696abfc
nb/intel/x4x: Fix and deflate `dimm_config` in raminit
It didn't fix the channel-number shifting issue as intended.
The channel index is either 0 or 1. DIMMs are counted from 0
to 3 where 0..1 covers channel 0, and 2..3 covers channel 1.
Since we have two DIMMs per channel, we have to multiply the
channel index by 2 (or shift it left by 1) to get the index
of the first DIMM in the channel. Finally, to get the offset
of a DIMM in the channel we take its index modulo 2 (again,
the number of DIMMs per channel).

RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

When MRC cache is available, first read only the SPD unique
identifier bytes required to detect possible DIMM replacement.
As this is 11 vs 256 bytes with slow SMBus operations, we save
about 70ms for every installed DIMM on normal boot path.
In the DIMM replacement case this adds some 10ms per installed DIMM
as some SPD gets read twice, but we are on slow RAM training boot path
anyways.

For S3 resume path SPD is only used for DIMM replacement detection.
As this detection already fails in the case of removal/insertion of
same DIMM, we can rely on cbmem_recovery() failure alone to force
system reset in case someone accidentally does DIMM replacements while
system is suspend-to-ram stage.
Skipping DIMM replacement detection allows skipping slow SPD loading,
thus reducing S3 resume path time by 80ms for every installed DIMM.

These settings should be always made by the firmware, no matter if we
set up graphics or not. It looks like Linux doesn't even know these
registers.
The values are taken from the PRMs for Sandy Bridge and Ivy Bridge [1,
2]. They match the settings that were done in the native graphics path
for Ivy Bridge. I expect the differences to be an update (i.e. the set-
tings we did on the Sandy Bridge path were just outdated). Also, these
settings affect the PCH and not the CPU which are independent from each
other.

This patch implements native resolution, VESA mode, on the VGA output of
x4x.
It relies on EDID to modeset, but has a fallback-mode (640 x 480 @
60Hz) if this is no EDID could be found. This fallback mode only works
in textmode since in VESA mode some payloads (grub2) rely on VBE info,
which is being generated from an EDID.

The datasheets on gm45: "Mobile Intel® 4 Series Express Chipset Family"
mention the possibility of having 352M ram preallocated for the
integrated graphic device. This only worked fine if the amount of ram in
the system was 3GB or less. When 4G or more is installed, memory is
remapped to create a 1GB large pci mmio hole which is not enough and
creates conflicts when 352M vram is used.
This patch increases the pci mmio hole size on Lenovo x200 to allow
352M vram to work.
TEST: build and flash on target with 4GB ram or more, use nvramtool to
set gfx_uma_size to 352M and reboot.

This reuses the Intel Pineview native graphic initialization
to have output on the VGA connector of i945 devices.
The behavior is the same as with the vendor VBIOS BLOB.
It uses the external VGA display if it is connected.

The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
on some targets hits a working mode at lower refresh rate, which is why
display is working on some targets.
The divisors must be such "refclk * (5 * (m1 + 2) + (m2 + 2))/ (n + 2)
/ (p1 * p2)" is as close as possible to the target frequency (which
is defined by the resolution and refresh rate).
This patch also fixes the reference frequency.
This patch reuses linux (4.1) code from drivers/gpu/drm/i915/intel_display.c
to correctly compute divisors.
The result is that some previously not working displays, like many
displays found on the Lenovo T60 might work now.
Some examples of T60 displays that were known to not work (in payload):
Samsung LTN141XA-L01 (14.1" 1024x768)
LG-Philips LP150X09 (15.1" 1024x768)
IDtech N150U3-L01 (15.1" 1600x1200)
IDtech IAQX10N (15.1" 2048x1536)
Samsung LTN154X3-L0A (15.4" 1280x800)
LG-Philips LP150E06-A5K4 (15.1" 1400x1050)
Tested on T60 with 1024x786.

This generates a fake VBT for the Intel i945 graphic device. i945
supports both the mobile chipset 945gm (calistoga) and the desktop
chipset 945gc (lakeport), which is why a VBT with a different id string
needs to be created for each target.
The VBT id string is obtained from the vbios blob in the following way:
"strings vbios.bin | grep VBT".
