baf27dbaeb cbfs: Enable CBFS mcache on most chipsets
This patch flips the default of CONFIG_NO_CBFS_MCACHE so the feature is
enabled by default. Some older chipsets with insufficient SRAM/CAR space
still have it explicitly disabled. All others get the new section added
to their memlayout... 8K seems like a sane default to start with.

3f11803075 soc/mediatek: Move auxadc driver from MT8183 to common
The auxadc (auxiliary analogue-to-digital conversion) is a unit
to identify the plugged peripherals or measure the temperature
or voltages.

The MT8183 auxadc driver can be shared by multiple MediaTek SoCs
so we should move it to the common folder.

46514c2b87 treewide: Add Kconfig variable MEMLAYOUT_LD_FILE
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows
SoC/mainboard to provide a linker file for the platform. x86 already
provides a default memlayout.ld under src/arch/x86. With this new
Kconfig variable, it is possible for the SoC/mainboard code for x86 to
provide a custom linker file as well.

Makefile.inc is updated for all architectures to use this new Kconfig
variable instead of assuming memlayout.ld files under a certain
path. All non-x86 boards used memlayout.ld under mainboard
directory. However, a lot of these boards were simply including the
memlayout from SoC. So, this change also updates these mainboards and
SoCs to define the Kconfig as required.

BUG=b:155322763
TEST=Verified that abuild with --timeless option results in the same
coreboot.rom image for all boards.

to select range[0].

Refer to the 'JESD209-4 - Low Power Double Data Rate 4X(LPDDR4X).pdf',

00961676fd Revert "soc/mediatek/mt8183: Force retraining memory if requested"
This reverts commit 285975dbba.

Reason for revert: VB2_RECOVERY_TRAIN_AND_REBOOT was never meant to have
any special effect on memory training behavior. It was just supposed to
be a "reboot automatically after reaching kernel verification" recovery
reason. On x86 devices this was used to prime the separate recovery
MRC cache in the factory (make sure it is initialized before shipping).

This isn't used on Kukui anyway, but in order to make sure nobody copies
this code and keep the behavior consistent between platforms, let's
remove it.

c79e96b4eb security/vboot: Decouple measured boot from verified boot
Currently, those who want to use measured boot implemented within
vboot should enable verified boot first, along with sections such
as GBB and RW slots defined with manually written fmd files, even
if they do not actually want to verify anything.

As discussed in CB:34977, measured boot should be decoupled from
verified boot and make them two fully independent options. Crypto
routines necessary for measurement could be reused, and TPM and CRTM
init should be done somewhere other than vboot_logic_executed() if
verified boot is not enabled.

In this revision, only TCPA log is initialized during bootblock.
Before TPM gets set up, digests are not measured into tpm immediately,
but cached in TCPA log, and measured into determined PCRs right after
TPM is up.

This change allows those who do not want to use the verified boot
scheme implemented by vboot as well as its requirement of a more
complex partition scheme designed for chromeos to make use of the
measured boot functionality implemented within vboot library to
measure the boot process.

TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in
CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

1c6d8a9cf4 soc: Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

998737df71 soc/mediatek/mt8183: Correct EMI bandwidth threshold for DVFS switch
Because eMCP and discrete DDR devices have different DVFS tables, their
EMI bandwidth thresholds should also be different. When the EMI total
bandwidth reaches the threshold, the system will notify DVFS module to
perform DVFS switch for system performance in low power states.

This patch increases the threshold from 0xa to 0xd for eMCP DDR devices
so that DVFS switch will be less likely to happen.

The register table of EMI_BWCT0 is incorrect in the datasheet. According
to the hardware design, BW_2ND_INT_BW_THR should be in bits [30:24]
instead of [22:16]. However, the logic in DRAM driver is correct,
aligned with the hardware design, so we don't need to correct it.

cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

Nvidia Tegra will be handled in a separate patch because it has a

Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

Mechanisms set in place to pass on information from rom- to ram-stage
