Disabling the MMU with proper cache behavior is a bit tricky on ARM64:
you can flush the cache first and then disable the MMU (like we have
been doing), but then you run the risk of having new cache lines
allocated in the tiny window between the two, which may or may not
become a problem when those get flushed at a later point (on some
platforms certain memory regions "go away" at certain points in a way
that makes the CPU very unhappy if it ever issues a write cycle to
them again afterwards).
The obvious alternative is to first disable the MMU and then flush the
cache, ensuring that every memory access after the flush already has the
non-cacheable attribute. But we can't just flip the order around in the
C code that we have because then those accesses in the tiny window
in-between will go straight to memory, so loads may yield the wrong
result or stores may get overwritten again by the later cache flush.
In the end, this all shouldn't really be a problem because we can do
both operations purely from registers without doing any explicit memory
accesses in-between. We just have to reimplement the function in
assembly to make sure the compiler doesn't insert any stack accesses at
the wrong points.

Some arm64 files that were imported from other projects use the
__ASSEMBLY__ macro to test whether a header is included from a C or an
assembly file. This patch switches them to the coreboot standard
__ASSEMBLER__, which has the advantage of being a GCC builtin so that
the including file doesn't have to supply it explicitly.

Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.
This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.
This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.
NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

* Introduce a weak function to add platform specific memranges.
* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.

Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having
the interrupt handling code available to all stages. In order
to do this the idt setup is moved to a C module. The vecX
entries are made global so that a table of references to all
the interrupt vector entry points can be used to dynamically
initialize the idt. The ramification for ramstage is that
exceptions are initialized later (lib/hardwaremain.c). Not
all stages initialize exceptions when this Kconfig variable
is selected, but bootblock for the C, stages using
assembly_entry.S, and of course ramstage do. Anything left
out just needs a call to exception_init() at the right
location.

Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.
In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.
The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

dimm_info.serial had a strange contract. The SPD spec defines a 4 byte
serial number. dimm_info.serial required a 4 character ascii string with
a null terminator.
This change makes the serial field so it matches the SPD spec.
smbios.c will then translate the byte array into hex and set it on the
smbios table.
There were only two callers that set the serial number:
* haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so
it already matches the new contract.
* amd_late_init.c: Previously copied the last 4 characters. Requires
decoding the serial number into a byte array.
google/cyan/spd/spd.c: This could be updated to pass the serial number,
but it uses a hard coded spd.bin.
Testing this on grunt, dmidecode now shows the full serial number:
Serial Number: 00000000

In order to support RISC-V processors with and without the RVC
extension, configure the architecture variant (-march=...) explicitly.
NOTE: Spike does support RVC, but currently doesn't select
ARCH_RISCV_COMPRESSED, because coreboot's trap handler doesn't
support RVC.

The RISC-V Privileged Architecture spec 1.10 requires that the address part of
mtvec is four-byte aligned. The lower two bits encode a "mode" flag and should
be zero for now.
Add the necessary alignment directive before trap_entry.

There are now a few architectural extensions available for ARMv8, some
of which introduce instructions or other features that may be useful.
This allows the user to select an extension implemented on their SoC
which will set the -march option passed into the compiler.

This patch changes the way coreboot builds ARM TF to pass the new
COREBOOT flag introduced with the following pull request:
https://github.com/ARM-software/arm-trusted-firmware/pull/1193
Since the new coreboot support code supports the CBMEM console, we need
to always enable LOG_LEVEL INFO. Supporting platforms will parse the
coreboot table to conditionally enable the serial console only if it was
enabled in coreboot as well.
Also remove explicit cache flushes of some BL31 parameters. Turns out we
never really needed these because we already flush the whole cache when
disabling the MMU, and we were already not doing it for most parameters.

The PNOT method never notifies the CPU to update it's _CST methods due
to reliance on inexisting variable (PDCx).
Add a method in the speedstep ssdt generator to notify all available
CPU nodes and hook this up in this file.
The cpu.asl file is moved to cpu/intel/speedstep/acpi since it now
relies on code generated in the speedstep ssdt generator. CPUs not
using the speedstep code never included this PNOT method so this is
a logical place for this code to be.

The commit 93bbd41e (soc/intel: Enable ACPI DBG2 table generation)
causes a crash on the mainboard mc_apl1. On this mainboard all internal
SOC UARTs in the devicetree are switched off. As a result, no resources
are allocated to the UARTs. The function find_resource() expects an
existing resource. Otherwise, the CPU will stop. It should therefore not
only be queried whether a device is present, but also whether it is
enabled.
