HAS_PRECBMEM_TIMESTAMP_REGION was dependent on COLLECT_TIMESTAMPS,
but should be allowed to be selected independently. My thought is that
the code may only be used when collecting timestamps, the HAS prefix
signifies that this is a platform configuration option.
This fix could also be done by adding 'if COLLECT_TIMESTAMPS' everywhere
that 'select HAS_PRECBMEM_TIMESTAMP_REGION' is used

On one particular TV the TV was holding SDA low when it came up. It
would release the SDA when the SCL went low the first time.
Unfortunately the HDMI i2c port wouldn't transmit until the SDA was
released.
Let's detect this case and insert a bogus clock pulse to try to get the
other side to release SDA.
It's unclear why the kernel doesn't have this problem.

This patch expands the existing ENV_<stage> macros in <rules.h> with a
set of ENV_<arch> macros which can be used to detect which architecture
the current compilation unit is built for. These are more consistent
than compiler-defined macros (like '#ifdef __arm__') and will make it
easier to write small, architecture-dependent differences in common code
(where we currently often use IS_ENABLED(CONFIG_ARCH_...), which is
technically incorrect in a world where every stage can run on a
different architecture, and merely kinda happened to work out for now).
Also remove a vestigal <arch/rules.h> from ARM64 which was no longer
used, and genericise ARM subarchitecture Makefiles a little to make
things like __COREBOOT_ARM_ARCH__ available from all file types
(including .ld).

The existing arm64 architecture code has been developed for the Tegra132
and Tegra210 SoCs, which only start their ARM64 cores in ramstage. It
interweaves the stage entry point with code that initializes a CPU (and
should not be run again if that CPU already ran a previous stage). It
also still contains some vestiges of SMP/secmon support (such as setting
up stacks in the BSS instead of using the stage-peristent one from
memlayout).
This patch splits those functions apart and makes the code layout
similar to how things work on ARM32. The default stage_entry() symbol is
a no-op wrapper that just calls main() for the current stage, for the
normal case where a stage ran on the same core as the last one. It can
be overridden by SoC code to support special cases like Tegra.
The CPU initialization code is split out into armv8/cpu.S (similar to
what arm_init_caches() does for ARM32) and called by the default
bootblock entry code. SoCs where a CPU starts up in a later stage can
call the same code from a stage_entry() override instead.
The Tegra132 and Tegra210 code is not touched by this patch to make it
easier to review and validate. A follow-up patch will bring those SoCs
in line with the model.

AMD Opteron processors contain a very fragile phy phase detection circuit.
Additionally, the algorithm given in the BKDG does not function as intended;
this was verified both on real hardware via execution trace and on paper
with values read back from multiple CPUs and DIMMs.
As a result, the phy training algorithm given in the BKDG has been
replaced with a phy training algorithm developed at Raptor Engineering.
This particular patch is the first part of that algorithm; the code
is updated in future patches but this should exist in the historical
record in case something breaks down in the later sections of code.

AMD's automatic phy phase detection hardware is very fragile and often
produces incorrect results. Attempt to recover from obvious phase
locking errors by retrying phy training on the failing link.

The existing MCT code did not properly set up the On Die Termination
(ODT) or timing values for registered DIMMs. Use the BKDG recommended
values when registered DIMMs are installed.

There were numerous issues surrounding AMD ECC initialization on
Family 15h processors due to the incomplete derivation from Family
10h MCT code. Bring the Family 15h ECC initialization and supporting
setup code in line with the BKDG recommendations.

The existing ECC initialization algorithm contained several bugs on both
Family 10h and Family 15h processors, including activation of ECC scrub
before DRAM setup was completed, in violation of both BKDG and errata
recommendations.
