The amd_mtrr.c file contains a copy of the fixed MTRR algorithm.
However, the AMD code needs to handle the RdMem and WrMem attribute
bits in the fixed MTRR MSRs. Instead of duplicating the code
with the one slight change introduce a Kconfig option,
X86_AMD_FIXED_MTRRS, which indicates that the RdMem and WrMem fields
need to be handled for writeback fixed MTRR ranges.
The order of how the AMD MTRR setup routine is maintained by providing
a x86_setup_fixed_mtrrs_no_enable() function which does not enable
the fixed MTRRs after setting them up. All Kconfig files which had a
Makefile that included amd/mtrr in the subdirs-y now have a default
X86_AMD_FIXED_MTRRS selection. There may be some overlap with the
agesa and socket code, but I didn't know the best way to tease out
the interdependency.

Commit »AMD S3: Introduce Kconfig variable 'S3_DATA_SIZE'« (22ec9f9a) [1]
introduced a check throwing an error if S3_DATA_SIZE isn't big enough.
However without CONFIG_HAVE_ACPI_RESUME the variable S3_DATA_SIZE
isn't defined at all and compilation will fail if s3_resume.h is
included.
This patch makes it again possible turn off HAVE_ACPI_RESUME relatively
easily in Parmer/Thatcher/Persimmon's Kconfig if you don't care about S3
and don't want flash writes on every boot.

This reverts commit ca6e1f6c04c96c435bdbf30a1b88cab0e5be330b.
The packet size changes ends up corrupting the flash when booting
Persimmon. I did figure out that the maximum number of bytes that
can be sent is actually 8 bytes according to the sb800 spec. There
must be additional problems beyond that since setting the packet
size to 8 still causes problems.

Currently the size of the volatile storage for S3 reserved in the
image is hardcoded to 32768 bytes. Make that configurable by
introducing the Kconfig 'S3_DATA_SIZE'.
As the storage space is needed for storing non-volatile, volatile and
MTRR data, add a check if the size is big enough.

REQUIRES_BLOB assumes that all blob files come from the 3rdparty directory,
builds failed when all files were configured to point to other sources.
This change modifies the blob mechanism so that cbfs-files can be tagged as
"required" with some specification what is missing.
If the configured files can't be found (wrong path, missing file), the build
system returns a list of descriptions, then aborts.

According to spi.c in src/southbridge/amd/agesa/hudson
readwrite = (bytesin + readoffby1) << 4 | bytesout;
We can see that Hudson limits the SPI programming data
packet size as 15.
We used to write data to SPI in dword mode. It didn't
take full advantage of the data packet size. We need to
leverage that to speed up programming time.

The SB800 and Hudson now support adding the IMC ROM which runs from the same
chip as coreboot. When the IMC is running, write or erase commands sent to
the spi bus will fail, and the IMC will die. To fix this, we send a request
to the IMC to stop fetching from the SPI rom while we write to it. This
process (in one form or another) is required for writes to the SPI bus while
the IMC is running.
Because the IMC can take up to 500ms to respond every time we claim the
bus, this patch tries to keep the number of times we need to do that to a
minimum. We only need to claim the bus on writes, and using a counter for
the semaphore allows us to call in once to claim the bus at the beginning
of a number of transactions and it will stay claimed until we release it
at the end of the transactions.
Claim() - takes up to 500ms hit
claim() - no delay
erase()
release()
claim() - no delay
write()
release()
Release()

As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).
Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.
For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
- from CAR setup (no need to reserve the space)
- commented out code (that was commented out for years)
- only copy sizeof(sysinfo) into RAM after ram init, where
before it copied the whole GLOBAL_VAR area.
- from Kconfig

These object files didn't provide any symbols that were used

The CPU can arbitrarily reorder calls to rdtsc, significantly
reducing the precision of timing using the CPUs time stamp counter.
Unfortunately the method of synchronizing rdtsc is different
on AMD and Intel CPUs. There is a generic method, using the cpuid
instruction, but that uses up a lot of registers, and is very slow.
Hence, use the correct lfence/mfence instructions (for CPUs that
we know support it)

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

Northbridge code incorrectly adjusted the last cacheable memory
resource to accomodate room for UMA framebuffer. If system had
4GB or more memory that last resource is not below 4GB and not
the one where UMA is located.
There are three consequences:
The last entry in coreboot memory table is reduced by uma_memory_size.
Due the incorrect code in northbridge code state.tomk,
end of last resource below 4GB, had not been adjusted.
Incrementing that by uma_memory_size diverts a region
possibly claimed for MMIO to RAM, as TOP_MEM is written.
Since the UMA framebuffer did not have IORESOURCE_CACHEABLE,
it was ignored from the MTRR setup and not set uncacheable.
The setting of TOP_MEM and TOP_MEM2, as well as all the MTRRs,
should be copied from BSP to all APs instead of deriving the data
separately for each Logical CPU.

Use state.tomk to refer TOP_MEM, largest RAM address below 4GB.
Use state.tom2k to refer TOP_MEM2, largest RAM address above 4GB.
When setting either TOP_MEM or TOP_MEM2, any RAM resource found
must fit below the set value. Thus, round register value upwards,
not downwards.

First issue fixed:
For multi-socket CPU the current implementation emitted
Processor objects for cores in the first CPU only. This
commit fixes the bug by really emitting one Processor
object for each core. However, the unlikely case of mixed
CPU models is still not handled correctly.
Second issue fixed:
One loop was wrong in case a processor in the table declares
no P-states at all. The rewritten loop is safe. Some possibly
dangerous array lengths were also fixed.
Third issue: on MP-boards the recommended ramp-voltage (RVO) is 0mV
according to the BKDG. The current implementation always set it
to 25mV. This commit selects 0 or 25mV depending on CONFIG_MAX_PHYSICAL_CPUS.
Fourth issue: If a processor without PowerNow! support was inserted in a
system with coreboot configured with SET_FIDVID then the boot process hanged
mysteriously and very early. Apparently because init_fidvid_ap tampers with
non-existing registers. This commit fixes the bug by bailing out
from init_fidvid_ap if PowerNow! capability is missing.

to {cpu|NB}/amd/agesa and {SB}/amd/agesa to shorten and
simplify the folder names.
There is also a fix to vendorcode/amd/agesa/lib/amdlib.c to
append "ull" to a trio of 64-bit hexadecimal constants to
allow abuild to run successfully.

States for AMA3000BEX5AR, SDA3100AIO3BX, and SDA3400AIO3BX
are from AMD document 30430 3.51. States for ADA3200AIO4BX
derived from SSDT of a MS-7135. States for TMDML34BKX5LD derived
from legacy PowerNow! table of a MS-7135, and therefore lack accurate

In fact I changed coreDelay before deleting
the code in fidvid that called it. But there're
still a couple of calls from src/northbridge/amd/amdmct/wrappers/mcti_d.c
Since the comment encouraged fixing something, I
parametrized it with the delay time in microseconds
and paranoically tried to avoid an overflow at pathological
moments.

Well, I understand it better like this, but maybe
it's only me, part of the changes are paranoic, and
the only effective change is for a factor depending on
mobile or not that I can't test.

Add an untested step in BKDG 2.4.2.8. I don't
have the hardware with Core Performance Boost and
I think it's only available in revision E that does
not even have a constant yet.

handling for Fam 10 in SVI mode.
Looking at BKDG the process for updating
Pstate Nb vid after warn reset seemed
more similar to the codethat was there fo
pvi than the one for svi, so I called the
pvi function passing a pvi/svi flag. I don't
find documentation on why should UpdateSinglePlaneNbVid()
be called in PVI, but since I can't test it,
I leave it as it was.
This patch showed some progress beyond fidvid in my
boar,d but only sometimes, most times it just didn't
work.

Factor out some common expressions.
Add an error message when coreboots hangs waiting for a pstate
that never comes (it happened to me), and throw some
paranoia at it for good mesure.
If I understood BKDG fam10 CPUs never need a software initiated vid transition,
because the hardware knows what to do when you just request
a Pstate change if the cpu is properly configured. In fact
unifying a little what PVI and SVI do was better for my board (SVI).
So I drop transitionVid, which I didn't understand either (why
did it have a case for PVI if it is never called for PVI ?
Why did the PVI case distinguigh cpu or nb when PVI is
theoretically single voltage plane ? ).
