This function should be using the RK_CLRSETBITS() macros to access the
special Rockchip write-mask registers, like the rest of our code. Also,
there were already existing bit field definitions for these bits that
should be used (although it makes sense to adjust them a bit to allow
passing in the channel number).

CB:50863 refactored the data_training() function to split out read gate
training into a separate function, but in the course of this forgot to
correctly initialize the local obs_err varible in the new function to 0.
This means that it will be used uninitialized, and when it happens to be
non-zero it makes the training process fail. Due to the convoluted
control flow in the function, it seems that GCC's static analyzer
couldn't pick up on this uninitialized use.
The whole variable is unnecessary anyway, all it's used for is to force
the function to return two lines below without doing anything with
side-effects in between. This patch removes the variable and simplifies
the code in all three training functions to avoid this uninitialized use
issue and make everything a bit more readable. (Also restore the
original pre-clang-format continuation line intendations for more
readability.)

This patch changes the memlayout macro infrastructure so that the size
of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx)
is stored in a separate _xxx_size symbol. This has the advantage that
region sizes can be used inside static initializers, and also saves an
extra subtraction at runtime. Since linker symbols can only be treated
as addresses (not as raw integers) by C, retain the REGION_SIZE()
accessor macro to hide the necessary typecast.

Currently it's not possible to add multiple graphics driver into

a single API that multiple graphics driver can use.
This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel+Aspeed on server platforms or
Intel+Nvidia on consumer notebooks.
The goal is to remove duplicated fill_fb_framebuffer(), the advertisment
of multiple indepent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.
Replace set_vbe_mode_info_valid with fb_add_framebuffer_info or
fb_new_framebuffer_info_from_edid.

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.

- Which incarnation of Google (Inc, LLC, ...) is the current

- People sometimes have their editor auto-add themselves to files even

- 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

Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.
Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

When CB:33068 disabled the bootblock console on RK3288, it saved a
whooping 7K of SRAM, but it didn't readjust the stage boundaries to
spread that bounty evenly. This patch moves 4K of free space from the
bootblock to verstage/romstage to allow for future expansion.

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).

RK3288 is running out of space again. I believe reducing the CBFS cache
size this much should be safe. I don't really care to test it either
though. We should probably just deprecate that SoC at some point, it's
just causing too much pain.
