The mt8183 dsi driver can be shared with mt819x SoC.
Move dsi.c to common/ folder and rename it to dis_v2.c to
differentiate it from mt8173's dsi driver.

mtk_init_mcu uses DRAM_DMA section as CBFS buffer.
The change "mediatek/mt8183: Remove DRAM_DMA section" is reverted
for using mtk_init_mcu.
On mt8173 and mt8192, this region is used by DMA hardware and is
marked as non-cacheable resource. On mt8183, this region is reserved
as CBFS buffer, so it is not necessary to be marked as non-cacheable
resource.

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

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.

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

The DQ vref should select correct range that corresponds to current frequency,

to select range[0].

This reverts commit 285975dbba8c7f3bbb9f9950e79a30bb983d5123.
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.

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().

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.

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.

When configuring MIPI DSI Tx, the value of pcw was calculated from data
rate in MHz, leading to loss of precision. This patch changes to use

In addition, change the type of data rate to u32, and calculation of

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).

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

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

Most coreboot debug messages are sent to UART and cbmem console, and we
also want to collect DRAM calibration module output, especially for
cbmem console (so we can see the logs after kernel is up).
Instead of sharing whole cbmem/cbtable/cbmemconsole implementations, we
want to simplify that by a simple function pointer so output can be
preserved by do_putchar, which internally sends data to all registered
consoles (usually cbmem console and UART).

If DRAM calibration fails or mem test fails using the cached calibration
results stored in flash, rerun DRAM full calibration. If partial
calibration fails or the mem test following it fails, hang forever.
Partial calibration acts as a fallback approach in case of full
calibration failure. Therefore, if it fails, there would be no other
ways to initialize DRAM. Instead of falling into reboot loop and
draining out of battery, it is better to just hang so that the end user
may notice that and send to RMA.
