Given that it sets the receive enable mode bit in the GDCRTRAININGMOD

Remove a potentially-outdated comment. Proper documentation will be

In order to run a write leveling test, one needs to unset the Qoff bit
in MR1, then run the test, and finally set Qoff again. The current IOSAV
sequence uses two subsequences to perform the test, while the other two
are unused. It is possible to perform the two necessary MR1 updates in
the same sequence, which can potentially improve runtime (not measured).
Since `write_mrreg` is no longer used, it is necessary to handle address
mirroring explicitly. This can be accomplished with the recently-added
`ddr3_mirror_mrreg` function, which is also used in `write_mrreg`.

AMD family 17h and newer don't use cache as RAM, since the RAM is
already initialized by the PSP when the x86 cores are released from
reset. Therefore they use a different linker script as the rest of the
x86 chips in coreboot do. Since there will be support for newer
generations than Picasso will be added, move those linker scripts from
soc/amd/picasso to soc/amd/common/block/cpu/noncar.
TEST=Timeless build of amd/mandolin and amd/gardenia result in identical

This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer
that stores the headers of all CBFS files. Similar to the existing FMAP
cache, this cache should reduce the amount of SPI accesses we need to do
every boot: rather than having to re-read all CBFS headers from SPI
flash every time we're looking for a file, we can just walk the same
list in this in-memory copy and finally use it to directly access the
flash at the right position for the file data.
This patch adds the code to support the cache but doesn't enable it on
any platform. The next one will turn it on by default.

As a part of trying to get our boot time as low as possible, any delays
in the code should try to be refactored out. This removes the 50ms
delay in the WIFI sequence by enabling power and putting the wifi module
into reset in bootblock, then bringing it out of reset in ramstage.
This is significantly longer than the 50ms requirement. The reset GPIO
was already being set high in ramstage, so that code didn't need to be
added.

Currently, the PCIe bridge 00:15.2 is not detected by coreboot, causing
the connected network device also to be missing.
This is caused by not configuring the third of the four PCIe General
Purpose Ports (GPP) of the AMD Fusion Controller Hub (FCH), which can be
exposed as one to four PCIe devices.
So, enable it in AGESA but disable enumeration in coreboot. Otherwise,
the serial console stops working in romstage after
[…]

PCI: 00:15.1 cmd <- 06

Add the _HID INT33A1 to PEPD to make Linux recognize it as "Intel Power
Engine" in the pmc core driver.
The _ADR gets dropped, because _HID and _ADR are mutually exclusive.

The PEPD enum function returns a bitmask to announce supported/enabled
PEPD functions. Add a comment describing this bitmask and correct the
return value to announce function 1, 5 and 6 as supported.
Also add comments to the disabled functions 3 and 4.

Windows does not comply with the Low Power Idle S0 specification and
crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does
not return at least one device constraint, even when function 1 is
announced as being not available by the enum function. Returning an
empty package does not work.
At least the following Windows versions were verified to be affected:
- Windows 8.1 x64, release 6.3.9600
- Windoes 10 x64, version 1809, build 17763.379
- Windows 10 x64, version 1903, build 18362.53
- Windows 10 x64, version 2004, build 19041.508
- Windows 10 x64, version 20H2 / 2009, build 19042.450
To make Windows work on S0ix-enabled boards, return a dummy constraint
package with a disabled dummy device.
Since the device constraints are only used for debugging low power
states in Linux and probably also in Windows, there shouldn't be any
negative effect to S0ix. Real device constraint entries could be added
at a later point, if needed.
Note: to fully prevent the BSOD mentioned above the LPIT table is
required on Windows, too. The patch for this is WIP, see CB:32350.
If you want to test this, you need to applie the whole ACPI patch
series including the hacky LPIT test implementation from CB:47242:
https://review.coreboot.org/q/topic:%22low_power_idle_fix%22
Test: no bluescreen anymore on Clevo L140CU on all Windows versions
listed above and S0ix gets detected in `powercfg -a`.

Move the UUID to the condition, since there is no need to assign a name
when it is only used once. Also add a comment to make clear that the
functions inside that condition are only used by the Low Power Idle S0
functionality, while the PEPD in general can be present on boards
without S0ix capability, too. For details check CB:46469.

This register must be programmed if Self-Refresh Temperature range is
enabled in MR2 (bit 7). Because the memory controller needs to reprogram
MR2 when entering Self-Refresh, it needs a copy of the MR2 settings. It
also needs to know about mirrored ranks to correctly issue MRS commands.

Instead of programming subsequences one-by-one, we might as well take
the whole sequence as an array and program all subsequences in one go.
Since the number of subsequences is now known in advance, handling of
global state can be simplified, which allows reusing the last sequence.
