b8a355dcdf northbridge/amd/amdmct: Fix broken AMD K10 DDR3 memory initalization
The native AMD DDR3 memory initialization code was riddled with
numerous errors and was missing critical configuration code segments;
this made it so that DDR3 memory did not function on most AMD boards.

This patch corrects enough of the DDR3 initialization such that
UDIMMs can be used on most channels of G34 Opteron boards.  Further
work is needed to fix the broken RDIMM code and remaining UDIMM issues.

6a4d6825ac amd/family14: Add k10temp thermal zone.
The thermal sensor interface exposed in function 3 of the northbridge is
a more convenient and faster way to access the processor-internal
thermal sensor than using the SMBus/SB-TSI interface from the FCH, see
the Family14 BKDG: "Tctl is a processor temperature control value used
for processor thermal management. Tctl is accessible through SB-TSI and
D18F3xA4[CurTmp]. Tctl is a temperature on its own scale aligned to the
processors cooling requirements"

Also on at least some of these boards the existing thermal zone is
broken and always returns 40C (the default value if the SMBus read
failed) because the SMBus muxing register (SmBus0Sel) is not set up
correctly.

Case in point: The fallback "smbus read failed" temperature is 40 C and
the the logs taken from the board status repository for the Asrock
E350M1 board all show: "ACPI: Thermal Zone [TZ00] (40 C)"
e.g.

fdbc1af5e2 Kconfig: Remove EXPERT mode
After much consideration, and many years of an EXPERT mode sitting
almost completely unused, we've seen that it doesn't work for us.
There is no standard on what constitutes EXPERT, and most of
coreboot's options Kconfig are expert-level.

We even joked that not selecting "EXPERT" should prevent coreboot
from compiling:

@echo $(shell whoami) is not permitted to compile coreboot

0dc7354760 amd: raminit sysinfo offset fix
The sysinfo object within the k8 ram init is used
to communicate progess/status from all the nodes in the
system. However, the code was assuming where the sysinfo
object lived in cache-as-ram. The layout of cache-as-ram
is dynamic so one needs to do the lookup of the correct
address at runtime. The way the amd code is compiled
by #include'ing .c files makes the solution a little
more complex in that some cache-as-ram support code
needed to be refactored.

58e26c74e0 northbridge/amd/amdfam10: Increase MMIO hole size to 1GB
On modern mainboards with multiple PCI-e devices and a single
graphics card the default MMIO hole size of 512M is inadequate,
leading to resource-hungry PCI-e devices (such as an external

turn, causes the entire PCI subsystem to become unavailable,
leading to a failure to boot.

operation of PCI/PCI-e devices, including text mode VGA operation
via the add-on card and its VGA option ROM.

7a8a4ab1d8 lib: Unify log2() and related functions
This patch adds a few bit counting functions that are commonly needed
for certain register calculations. We previously had a log2()
implementation already, but it was awkwardly split between some C code
that's only available in ramstage and an optimized x86-specific
implementation in pre-RAM that prevented other archs from pulling it
into earlier stages.

Using __builtin_clz() as the baseline allows GCC to inline optimized
assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and
to perform constant-folding if possible. What was previously named log2f
on pre-RAM x86 is now ffs, since that's the standard name for that
operation and I honestly don't have the slightest idea how it could've
ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm
with Float result, whereas the Find First Set operation has no direct
correlation to logarithms that I know of). Make ffs result 0-based
instead of the POSIX standard's 1-based since that is consistent with
clz, log2 and the former log2f, and generally closer to what you want
for most applications (a value that can directly be used as a shift to
reach the found bit). Call it __ffs() instead of ffs() to avoid problems
when importing code, since that's what Linux uses for the 0-based
operation.

CQ-DEPEND=CL:273023
BRANCH=None
BUG=None
TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new
log2() and __ffs() results on Falco for a bunch of test values.

If SB_HT_CHAIN_ON_BUS0 is selected, HyperTransport chain for System Bus
is the first to scan and it will be assigned with bus number 0.

If HT_CHAIN_DISTRIBUTE is selected, each link will reserve a fixed range
of bus numbers instead of assigning consecutive numbers across all the links.

All fam10 have SB_HT_CHAIN_ON_BUS0 selected under northbridge.
Follow-up can easily drop this if we find this is dictated by architecture.

Based on code analysis, these boards already scan system bus
as the first (active) HT chain, so it is placed as bus 0
even when this option was not explicitly selected.
