This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted
context, and also dump a part of the current stack. Since we cannot
access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

On x86, cpu_info lives at the top of stack. Make the arm do that as
well, as the threading model needs that and so will multicore support.
As part of this change, make the stack size a power of 2.
Also make it much smaller -- 2048 bytes is PLENTY for ram stage.
Note that the small stack size is counterintuitive for rom stage. How
can this work in rom stage, which needs a HUGE stack for lzma? The
main use of STACK_SIZE has always been in ram stage; since 2002 or so
it was to size per-core stacks (see, e.g.,
src/arch/x86/lib/c_start.S:.space CONFIG_MAX_CPUS*CONFIG_STACK_SIZE
and, more recently, thread stacks. So, we define the STACK_TOP for rom
and ram stage, but the STACK_SIZE has no real effect on the ROM stage
(no hardware red zones on the stack) and hence we're ok with actually
defining the "wrong" stack size. In fact, the coreboot_ram ldscript
for armv7 sizes the stack by subtracting CONFIG_STACK_BOTTOM from
CONFIG_STACK_TOP, so we replicate that arithmetic in bootblock.inc
Observed stack usage in ramstage:
BS: BS_PAYLOAD_LOAD times (us): entry 1 run 153887 exit 1
Jumping to boot code at 23104044
CPU0: stack: 02072800 - 02073000, lowest used address 020728d4, stack used: 1836 bytes
entry = 23104044
Which means we do need 2K, not 1K.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

There is redundancy in terms of use of init_timer. We have a Kconfig option to
decide whether a board has init_timer as well as we use a stub for init_timer in
places where we do not have any init_timer defined. Thus, remove the Kconfig
option. Henceforth, all boards that do not have init_timer functionality can
include a stub_timer if required.

Up until now, we were building AGESA by specifying each AGESA source
file and adding it to the list of romstage and ramstage source files.
As a result, we were compiling each AGESA source twice, despite the
fact that it does not depend on the stage we're in.
Since AGESA is stage-independent, we can build it just once, and use
the resulting static library in both rom and ram stages.
We still keep the practice of specifying every single AGESA directory
as an include dir and adding the AGESA CFLAGS to our global CFLAGS;
this is needed due to the way AGESA builds.

With the recent improvement 3d6ffe76f8,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly

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.

Intel CPUs. The same function is used to inject the update in both CBFS

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

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.

make a few corrections along the way. To summarize:
- clk_bit_info is no longer used. It had numerous errors and was
really painful anyway since it was just a bunch of opaque magic
numbers that made bugs non-obvious.
- Clock source bitfields for peripherals handled in the switch
statement are 3 bits, not 4. Some divider values are 3 bits,
some are 4. The earlier code always assumed 4 bits for both
which included reserved bits in many cases.
- UART source clock and divider shift values were wrong.
- PWM clock divider was being read from the wrong register.
- SPI3 divider value was being read from the wrong register.
- There was a really confusing calculation for SDMMC0 and SDMMC2
clock rates, but it was never actually used since the switch
statement never handled PERIPH_ID_SDMMC{0,2} and would thus
return if they were ever passed into this function.

Configure the pins for the UART unconditionally in the mainboard code (when we

the UART will work if later software wants to use it without setting up the
pins.

This patch implements the basic infrastructure required to use the USB
A-A firmware upload feature on Exynos5 processors with Coreboot. It will
require a corresponding host-side script that activates the feature and
uploads the correct image parts in the correct order to harcoded target
addresses, as described in the comments of alternate_cbfs.c.
Also fixes a bug in the Google Snow mainboard where it would not
correctly initialize the pinmux configuration for the SPI flash bus.
During a normal SPI boot the IROM would already do that for you, but
when booting from USB you have to do it yourself.

The existing GPIO config routines for SDMMC0-2 are over-generalized
and somewhat confusing as a result. It would work nicely if all SDMMC
ports were configured in the same fashion, but there are a few
exceptions.
For example, the inner function runs differently if we're using 8 bits
of data instead of 4, so a big chunk is skipped for SDMMC2. SDMMC0
requires SD_0_CDn to be an output rather than alternate function and
must have a value set.
This patch trades some verbosity for simplicy. Now the SDMMC GPIO
configuration a straight-forward sequence of GPIO operations
without any exceptions.

This includes the new dp code, which is better, and the fimd code,
which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.
With these changes we get graphics.
Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.
The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

The original intention was to only run UPDATE_FIT when a microcode file was
included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or
CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that
CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on
hasswell, the UPDATE-FIT step was always run, even when no microcode was
included, generating a build error.
Instead, introduce a new variable which tells if a microcode update is
added in CBFS during the build.

Commit * bdafcfa Add the Intel FSP 206ax CPU core support
Introduced this option. This option was meant to have a board generate
a CBFS file containing microcode. However, microcode generation used to be
enabled by default when CPU_MICROCODE_IN_CBFS was selected.
The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic
default, which is not what we want. This option is misguided in the sense
that it tends to introduce a non-default which had been intentionally a
default. We now have to select two Kconfig options in order to generate
microcode in CBFS, meaning one option is redundant.

ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C7S long latency)
ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:

The recommendation from Intel is to report each core as a
separate logical domain in the _PSD table.
This goes against the recommendation in the ACPI specification
because all of these cores are on the same package and share a
VR so they will do voltage transitions together.
The reasoning is that with a larger number of logical processors
the P-state often ramps too quickly resulting in higher power
consumption. By exposing each core as a separate domain the OS
can manage them individually allowing the socket to select the
optimum frequency.

Split the Parmer, Family 15tn, and Hudson DSDT into groups. This splits
the DSDT table into includable ASL files which carry details specific
to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The
dsdt.asl file in the mainboard directory contains only #include
references to the appropriate files.
Initially, this split was done by moving each piece of functionality
into its own file (e.g. IRQ routing and mapping, processor tree, sleep
states and sleep methods, etc.) and those pieces were #included in
dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d)
with the extant version of the table. Once the new tables were found
to exactly match the existing tables, the pieces were rearranged into
reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.).
Some include files have no content but are left as a template for
other platforms and as placeholders for completing the ACPI
implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl,
sata.asl, etc.).

The SOC's built in ROM loads the bootblock and the ROM stage into the on chip
memory before handing over control to the bootblock. To avoid having to add
one or more driver to the bootblock so that it can re-load the ROM stage from
whatever media Coreboot is stored on, we can just take advantage of the copy
that's already there. Loading the RAM stage/payloads won't be so simple,
so the ROM stage and the RAM stage will have to have different media drivers.

This variable wasn't being defined and was defaulting to zero when used in the
ROM stage's linker script. This change defines it as a variable, and gives it
a value which is slightly beyond the end of the bootblock. By making the ROM
stage request to be loaded slightly farther into memory than it was loaded by
the SOC's masked ROM, we ensure that it's moved away from the stage's metadata
instead of on top of it. When it moves the other way, it clobbers important
values like the entry point vefore the bootblock has had a chance to use them.
