The skylake-based Chromebooks use a separate verstage which runs
just after bootblock and prior to romstage. The normal path for
romstage would be to reload the gdt, however in the previously
described scenario has verstage performing that work. Therefore,
provide that path under those conditions. The only difference
from the C_ENVIRONMENT_BOOTBLOCK scenario is that the stack
should not be reloaded since there's no way to know the top
of the stack.

The path that just clears CAR_GLOBAL variables and jumps
to the stage entry point needs another condition for
separate verstage just after bootblock. However, the
current conditional is a negative conditional so
swap the logic around to make it easier to extend.

In addition to being consistent with all other architectures,
all chipsets support cbmem so the low coreboot table path is
stale and never taken. Also it's important to note the memory
written in to that low area of memory wasn't automatically
reserved unless that path was taken. To that end remove
low coreboot table support for x86.

Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:
1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.
Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

On non-x86 platforms, coreboot uses the memlayout.ld mechanism to
statically allocate the different memory regions it needs and guarantees
at build time that there are no dangerous overlaps between them. At the
end of its (ramstage) execution, however, it usually loads a payload
(and possibly other platform-specific components) that is not integrated
into the coreboot build system and therefore cannot provide the same
overlap guarantees through memlayout.ld. This creates a dangerous memory
hazard where a new component could be loaded over memory areas that are
still in use by the code-loading ramstage and lead to arbitrary memory
corruption bugs.
This patch fills this gap in our build-time correctness guarantees by
adding the necessary checks as a new intermediate Makefile target on
route to assembling the final image. It will parse the memory footprint
information of the payload (and other platform-specific post-ramstage
components) from CBFS and compare it to a list of memory areas known to
be still in use during late ramstage, generating a build failure in case
of a possible hazard.

This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the
TIMESTAMP region, reducing configuration redundancy and avoiding
confusion when setting up future boards.
(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

The PSTATE mask bits for Debug exceptions, external Aborts, Interrupts
and Fast interrupts are usually best left unset: under normal
circumstances none of those exceptions should occur in firmware, and if
they do it's better to get a crash close to the code that caused it
(rather than much later when the kernel first unmasks them). For this
reason arm64_cpu_init unmasks them right after boot. However, the EL2
payload was still running with all mask bits set, which this patch
fixes.
BL31, on the other hand, explicitly wants to be entered with all masks
set (see calling convention in docs/firmware-design.md), which we had
previously not been doing. It doesn't seem to make a difference at the
moment, but since it's explicitly specified we should probably comply.
BRANCH=None
BUG=None
TEST=Booted Oak, confirmed with raw_read_daif() in payload that mask
bits are now cleared.

On ARM64, the memory type for accessing page table descriptors during
address translation is governed by the Translation Control Register
(TCR). When the MMU code accesses the same descriptors to change page
mappings, it uses the standard memory type rules (defined by the page
table descriptor for the page that contains that table, or 'device' if
the MMU is off).
Accessing the same memory with different memory types can lead to all
kinds of fun and hard to debug effects. In particular, if the TCR says
"cacheable" and the page tables say "uncacheable", page table walks will
pull stale entries into the cache and later mmu_config_range() calls
will write directly to memory, bypassing those cache lines. This means
the translations will not get updated even after a TLB flush, and later
cache flushes/evictions may write the stale entries back to memory.
Since page table configuration is currently always done from SoC code,
we can't generally ensure that the TTB is always mapped as cacheable.
We can however save developers of future SoCs a lot of headaches and
time by spot checking the attributes when the MMU gets enabled, as this
patch does.

Some newer x86 systems can boot from non-memory-mapped boot media
(e.g. EMMC). The bootblock may be backed by small amounts of SRAM, or
other memory, similar to how most ARM chipsets work. In such cases, we
may not have enough code space for romstage very early on. This means
that CAR setup and early boot media (e.g. SPI, EMMC) drivers need to
be implemented within the limited amount memory of storage available.
Since the reset vector has to be contained in this early code memory,
the bootblock is the best place to implement loading of other stages.
Implement a bootblock which does the minimal initialization, up to,
and including switch to protected mode. This then transfers control
to platform-specific code. No stack is needed, and control is
transferred via a "jmp" such that no stack operations are involved.

Since the introduction of the new (interim?) master header, coreboot
searches the whole ROM for CBFS entries. Fix that by aligning it on top
of the ROM.

In order for a U-boot payload to work properly the soc_registers
region (device registers) needs to be mapped as uncached.
Therefore, add a coherency argument to the identity mapping funcion
which will establish the type of mapping.

When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following:
AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030]
Decoding the faulting address:
0x000000fdf9103300
fdf91x Hypertransport system management region
33 SysMgtCmd (System Management Command) = 0x33
3 Base Command Type = 0x3: STPCLK (Stop Clock request)
3 SMAF (System Management Action Field) = [3:1] = 0x1
1 Signal State Bit Map = [0] = 0x1
Therefore, the error appears to be triggered by an upstream C1E request.
This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup. Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash
controller, thus placing the SP5100 in an invalid state. This limitation is not documented
in any public AMD errata, and was only discovered through considerable debugging effort.

The Chrome OS verified boot path supported multiple CBFS
instances in the boot media as well as stand-alone assets
sitting in each vboot RW slot. Remove the support for the
stand-alone assets and always use CBFS accesses as the
way to retrieve data.
This is implemented by adding a cbfs_locator object which
is queried for locating the current CBFS. Additionally, it
is also signalled prior to when a program is about to be
loaded by coreboot for the subsequent stage/payload. This
provides the same opportunity as previous for vboot to
hook in and perform its logic.

We currently race in SMM init on Atom 230 (and potentially
other CPUs). At least on the 230, this leads to a hang on
RSM, likely because both hyperthreads mess around with
SMBASE and other SMM state variables in parallel without
coordination. The same behaviour occurs with Atom D5xx.
Change it so first APs are spun up and sent to sleep, then
BSP initializes SMM, then every CPU, one after another.
Only do this when SERIALIZE_SMM_INITIALIZATION is set.
Set the flag for Atom CPUs.
