Prefer a smaller valid value over the measured one for
initial timB timings.
Final testing result:
Tests on x220 shows that the issue was resolved.
The test system booted successfully ten times in a row.
Tests on Gigabyte GA-B75M-D3H revealed no regressions.
Test system:
* Intel Pentium CPU G2130
* Gigabyte GA-B75M-D3H
* DIMM: "Crucial 2GB 256Mx64 CT2566aBA160BJ"

This patch removes the old arm64/stage_entry.S code that was too
specific to the Tegra SoC boot flow, and replaces it with code that
hides the peculiarities of switching to a different CPU/arch in ramstage
in the Tegra SoC directories.

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.

CAR space on certain platforms is nearly full. This prevents the
addition of necessary RAM initialization features such as x4 DIMM
support. As the DIMM SPD cache uses a sizeable amount of CAR RAM,
reducing it would free up a significant amount of CAR RAM.
DDR3-based AMD platforms only support up to 3 physical DIMMs on
each channel (6 per node). Reduce the maximum number of DIMMs
on a node from 8 to 6 accordingly.

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.

However, one needs to ensure it's set at least once otherwise

In practice this doesn't matter unless somone wants to use the

The elog format stores the year of the event in bcd format.
Semi-recently rtc_get() started returning the full year,
e.g. 2015. However, bin2bcd takes a uint8_t as a parameter.
Converting a full year (2015 or 0x7df) to a uint8_t results
in passing bad values (223 or 0xdf) to bin2bcd. In other words
the input value of bin2bcd needs to be a number between 0 and 99.
Therefore fix that mistake.

The SB700 silicon is somewhat buggy; if the links come up in an
incorrect state after POR the silicon cannot automatically recover.
If a disk fails to come online, reset the associated link and try
disk detection again.

The existing code enabled ECC before clearing memory. As the
AMD CPUs will generate MCEs on any invalid check bits, this
resulted in random lockups during memory training due to the
uniniailized check bits.
Initialize ECC check bits before enabling ECC hardware.

In AHCI mode SeaBIOS randomly fails to detect disks (AHCI timeouts),
with the probability of a failure increasing with the number of disks
connected to the controller. Resetting the SATA controller appears to
show the true state of the underlying hardware, allowing the drive
detection code to attempt link renegotiation as needed.

Certain DIMMs, for example DIMMs on which the EEPROM has been modified
by the end user, may not contain a valid SPD checksum. While this is
not a normal condition, it may be useful to allow a checksum override
while memory timing parameters are being altered, e.g. in the course
of overclocking or underclocking, or when recovering from a bad SPD
write.
This is an advanced level feature primarily useful for debugging
and development.

have the option to disable Active Link Power Management for two
reasons. First, some drives may not function correctly with the
ALPM implementation of the SP5100, and second there are some
situations where low latency access is more important than the
power savings created by using ALPM.

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.

DRAM training accounts for most of the romstage startup time, yet
if the hardware configuration has not changed from the previous boot
the previously discovered training values are still valid. Use them
if the DIMM configuration has not changed since the last boot.
The SPD values of all installed DIMMs are hashed and stored in the S3
resume data area of the main system Flash device. If a DIMM is changed
the hash will almost certainly change as well, forcing retraining on next
boot.

When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.
This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.

In order to have a proper runtime-modifyable page table API (e.g. to
remap DRAM after it was intialized), we need to remove any external
bookkeeping kept in global variables (which do not persist across
stages) from the MMU code. This patch implements this in a similar way
as it has recently been done for ARM32 (marking free table slots with a
special sentinel value in the first PTE that cannot occur as part of a
normal page table).
Since this requires the page table buffer to be known at compile-time,
we have to remove the option of passing it to mmu_init() at runtime
(which I already kinda deprecated before). The existing Tegra chipsets
that still used it are switched to instead define it in memlayout in a
minimally invasive change. This might not be the best way to design this
overall (I think we should probably just throw the tables into SRAM like
on all other platforms), but I don't have a Tegra system to test so I'd
rather keep this change low impact and leave the major redesign for
later.
Also inlined some single-use one-liner functions in mmu.c that I felt
confused things more than they cleared up, and fixed an (apparently
harmless?) issue with forgetting to mask out the XN page attribute bit
when casting a table descriptor to a pointer.

Among its other restrictions (which are noted in a comment above the
function prototype and stay in place), our makeshift fine-grained page
table support for ARM32 has the undocumented feature that it relies on
a global bookkeeping variable, causing all sorts of fun surprises when
you try to use it from multiple stages during the same boot. This patch
redesigns the bookkeeping to stay completely inline in the (persistent)
TTB which should resolve the issue. (This had not been a problem on any
of our platforms for now... I just noticed this because I was trying to
solve the same issue on ARM64.)

TEST=Booted veyron_jerry. Mapped a second fine-grained memory range
from romstage, confirmed that it finds the next free spot and leaves the
bootblock table in place.

Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over
I2C on a system with all DIMM slots populated. If even one of those reads
has a single flipped bit in it (due to EMI, cross coupling with another trace,
or just poor margins on some cheap DIMM) the system will hang and require a
hard reset. In practice I've seen failure rates as high as 1 failed boot in
50 due to this issue, granted with cheap DIMMs, but even so retrying the read
resolves the corruption issue.
I2C is not designed for continuous data transmission with high reliability, and
there is no hardware error checking, therefore a single retry when transferring
this amount of data makes sense.
