Aaron Durbin 04de97113a rmodules: fix linking
In commit ec5e5e0d the rmodules linking flags were dropped.
This resulted in relocations being removed from the ELF file.
The relocation information is quite valuable when needing to
perform relocations at runtime.

Vadim Bendebury fc934b2da2 mips: add c0 register access plumbing
C0 is a coprocessor register set defined in certain MIPS
architectures. This patch adds macros necessary to access the
registers and a couple of helper macros to access two particular
registers needed in the next patch.

The definitions come straight from arch/mips/include/asm/mipsregs.h in
the 3.14 kernel tree.

Kconfig's include directive "source" does not support
wildcards (e.g. source src/mainboard/*/Kconfig) which
makes automatic inclusion of all boards a tedious task

In our Makefile.inc files we already include mainboard
directories per wildcard, so let's add the infrastructure
to do the same with Kconfig.

Julius Werner ec5e5e0db2 New mechanism to define SRAM/memory map with automatic bounds checking
This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.

The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies

Julius Werner 015f0aea5d Add predefined __ROMSTAGE__ and __RAMSTAGE__ macros
This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.

This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)

It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.

BUG=None
TEST=None (tested together with dependent patch).

Ben Zhang 573429b09d samus: Set codec PDM clock output to 3MHz
Currently the rt5677 codec outputs 6MHz PDM clock which is
out-of-spec for the speaker amp SSM2537. The amp's GAIN_FS
pin is pulled down to PGND with a 47k resistor, so the
expected PDM clock is 64*FS (~3MHz) according to its datasheet.

The corresponding kernel patch that adds the PDM clock config
option is https://chromium-review.googlesource.com/#/c/230303/

BUG=chrome-os-partner:33303
BRANCH=samus
TEST=flash coreboot with this patch and see PDM CLK went
from 6MHz to 3MHz on samus with a scope.
