0f333071ef coreboot: infrastructure for different ramstage loaders
There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.

To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

ca4f4b8c9e mtrr: only add prefetchable resources as WRCOMB for VGA devices
Be more conservative and only add VGA devices' prefetchable
resources as write-combining in the address space. Previously
all prefetchable memory was added as a write-combining memory
type. Some hardware incorrectly advertises its BAR as
prefetchable when it shouldn't be.

A new memranges_add_resources_filter() function is added
to provide additional filtering on device and resource.

ba6b07e888 cpu/intel: allow non-packaged scoped turbo setting
In the past the turbo disable setting (bit 38) of the
IA32_MISC_ENABLES msr has been package scoped. That means
knocking the turbo disable bit down enabled turbo for the
entire package. Sadly, that's no longer true on all Intel
processors. Therefore, allow non-packaged scoped turbo
setting by introducing the CPU_INTEL_TURBO_NOT_PACKAGE_SCOPED
Kconfig option. It defaults to false which was the original
assumption.

e0785c0331 x86: parallel MP initialization
Provide a common entry point for bringing up the APs
in parallel. This work is based off of the Haswell one
which can be moved over to this in the future. The APs
are brought up and have the BSP's MTRRs duplicated in
their own MTRRs. Additionally, Microcode is loaded before
enabling caching. However, the current microcode loading
support assumes Intel's mechanism.

The infrastructure provides a notion of a flight plan
for the BSP and APs. This allows for flexibility in the
order of operations for a given architecture/chip without
providing any specific policy. Therefore, the chipset
caller can provide the order that is required.

2c38f50b4a cpu/intel: Make all Intel CPUs load microcode from CBFS
The sequence to inject microcode updates is virtually the same for all
Intel CPUs. The same function is used to inject the update in both CBFS
and hardcoded cases, and in both of these cases, the microcode resides in
the ROM. This should be a safe change across the board.

The function which loaded compiled-in microcode is also removed here in
order to prevent it from being used in the future.

The dummy terminators from microcode need to be removed if this change is
to work when generating microcode from several microcode_blob.c files, as
is the case for older socketed CPUs. Removal of dummy terminators is done
in a subsequent patch.

107f72e674 Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRR
This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.

Side-effects to consider:

Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.

With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

ffd4a610ba cpu/allwinner/a10: Import raminit code from uboot
The memory initialization code is a work in progress for uboot, so we
only import the bits needed to get RAM up and running. Any refactoring
is cosmetic, and any functional refactoring should be done in separate
patches, and preferably, in coordination with the sunxi team.
Since it's not yet determined if we should initialize memory during
the bootblock or romstage, we don't add raminit to the build just yet.

cce6c1c92a cpu/allwinner/a10: Add low-level helpers for DRAM clock control
PLL5 is special in that it controls the DRAM clock, and requires a
fine-grained low-level control which will be needed by raminit code.
This change also brings functionality which will be needed by
raminit.

5d8b0a9fb3 cubieboard: Initialize memory in bootblock
Even though the Allwinner A10 is limited to a 24KiB bootblock, the
memory initialization takes only about 3KiB and leaves enough room for
an MMC or NAND driver, so init the memory early on. The advantage is
that we can eliminate complicated logistics of where to cache CBFS and
where to load the ramstage in SRAM.

bc30b2b225 cpu/allwinner/a10: Refactor API for gating clocks to peripherals
Rather than having to track which bit in which register should be
cleared or set to gate or ungate the clock to a certain peripheral,
provide a simplified enum which encodes the register and bit. This
change comes with a function which decodes the enum and gates/ungates
the clock.

This also removes the register-dependent bitmasks for APB0 and APB1
gating registers.
