There's no need to wrap these macros with casts. Removing them allows
dropping more casts in `early_init.c`.
To avoid binary changes the casts are put into the
{MCH,DMI,EP}BAR{8,16,32} macros instead where they are needed to reach
the right memory locations.

This patch introduces two new CBFS API functions which are equivalent to
cbfs_map() and cbfs_load(), respectively, with the difference that they
always operate on the read-only CBFS region ("COREBOOT" FMAP section).
Use it to replace some of the simple cases that needed to use
cbfs_locate_file_in_region().

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

This patch flips the default of CONFIG_NO_CBFS_MCACHE so the feature is
enabled by default. Some older chipsets with insufficient SRAM/CAR space
still have it explicitly disabled. All others get the new section added
to their memlayout... 8K seems like a sane default to start with.

In order to run a write leveling test, one needs to unset the Qoff bit
in MR1, then run the test, and finally set Qoff again. The current IOSAV
sequence uses two subsequences to perform the test, while the other two
are unused. It is possible to perform the two necessary MR1 updates in
the same sequence, which can potentially improve runtime (not measured).
Since `write_mrreg` is no longer used, it is necessary to handle address
mirroring explicitly. This can be accomplished with the recently-added
`ddr3_mirror_mrreg` function, which is also used in `write_mrreg`.

Currently the decision of whether or not to use mrc_cache in recovery
mode is made within the individual platforms' drivers (ie: fsp2.0,
fsp1.1, etc.). As this is not platform specific, but uses common
vboot infrastructure, the code can be unified and moved into
mrc_cache. The conditions are as follows:
1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain
switch is true)
2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this
means that memory training will occur after verified boot,
meaning that mrc_cache will be filled with data from executing
RW code. So in this case, we never want to use the training
data in the mrc_cache for recovery mode.
3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this
means that memory training happens before verfied boot, meaning
that the mrc_cache data is generated by RO code, so it is safe
to use for a recovery boot.
4. Any platform that does not use vboot should be unaffected.
Additionally, we have removed the
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the
mrc_cache driver takes care of invalidating the mrc_cache data for
normal mode. If the platform:
1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data
2. HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set
BUG=b:150502246
BRANCH=None
TEST=1. run dut-control power_state:rec_force_mrc twice on lazor

2. remove HAS_RECOVERY_MRC_CACHE from lazor Kconfig

Provide necessary romstage hooks to allow unblocking the memory with
SCLEAN. Note that this is slow, and took four minutes with 4 GiB of RAM.
Tested on Asrock B85M Pro4 with tboot. When Linux has tboot support
compiled in, booting as well as S3 suspend and resume are functional.
However, SINIT will TXT reset when the iGPU is enabled, and using a dGPU
will result in DMAR-related problems as soon as the IOMMU is enabled.
However, SCLEAN seems to hang sometimes. This may be because the AP
initialization that reference code does before SCLEAN is missing, but
the ACM is still able to unblock the memory. Considering that SCLEAN is
critical to recover an otherwise-bricked platform but is hardly ever
necessary, prefer having a partially-working solution over none at all.

MRC does not use the value of SSKPD, and will overwrite it with constant
values at the end of memory initialisation. Since coreboot does not rely
on this particular bit's value, it is safe to drop the writes to set it.
MCHBAR register 0x6120 is undocumented. It is nowhere to be found in any
documentation or code I have access to; not even for Sandy/Ivy Bridge,
the platform where this mysterious register write originally came from.
These workarounds were copied from Sandy Bridge, but do not apply to
Haswell. They were dropped on Broadwell, so drop them for Haswell too.

This register had a lock bit on Sandy Bridge, but does not on Haswell.
Moreover, the bit remains cleared on Asrock B85M Pro4 with coreboot.
Therefore, remove the write to this bit, because it has no effect.
Tested on Asrock B85M Pro4, still boots.

There's no need to have ACPI guards in `gm45.h`, since the only things
the ASL files require are the base address definitions in `memmap.h`.
Also, remove the southbridge include from `gm45.h` and place it only in
the files that actually require something from it.
Tested with BUILD_TIMELESS=1, Roda RK9 remains identical.

Add definitions for more DMIBAR/EPBAR registers, and specify their sizes
as well. Also, expand a comment as the registers' purpose is now known.
Tested with BUILD_TIMELESS=1, Roda RK9 does not change.

The host bridge PCI device ID can be changed by the firmware. There
is no documentation about it, though. There's 'official' IDs, which
appear in spec updates and Windows drivers, and 'mysterious' IDs,
which Intel doesn't want OSes to know about and thus are not listed.
The current coreboot code seems to be able to change the device ID
of the host bridge, but it seems to be missing a warm reset so that
the device ID changes. Account for the 'mysterious' device IDs in
the northbridge driver, so that booting an OS has a chance to work.
For the sake of completeness, add the PCI device IDs for Clarkdale.
Although only Arrandale is known to work, both of them are Ironlake.
It is possible that the Management Engine handles changing the PCI
device ID, which would not happen when using a broken ME firmware.

The code is known to work on processors other than just i7's. Also, use
the northbridge's name (Ironlake) in place of the CPU's (Arrandale).

Remove unnecessary arrays, use unsigned types for non-negative values
and constify where possible. Also define NUM_CHANNELS and NUM_SLOTS.
