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cannot go missing or out of date.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
with ToT and looked for red flags.

b3847e6424 program loading: add prog_run() function
The prog_run() function abstracts away what is required
for running a given program. Within it, there are 2
calls: 1. platform_prog_run() and 2. arch_prog_run().
The platform_prog_run() allows for a chipset to intercept
a program that will be run. This allows for CPU switching
as currently needed in t124 and t132.

3948e5392b program loading: introduce struct prog
The struct prog serves as way to consolidate program
loading. This abstraction can be used to perform more
complicated execution paths such as running a program
on a separate CPU after it has been loaded. Currently
t124 and t132 need to do that in the boot path. Follow
on patches will allow the platform to decide how to
execute a particular program.

Note: the vboot path is largely untouched because it's
already broken in the coreboot.org tree. After getting
all the necessary patches pushed then vboot will be
fixed.

c3e7c4e7b4 Clean up architecture-specific Kconfigs
It's an unfortunate side effect of our different-archs-per-stage
mechanism that all src/arch/*/Kconfig files are always parsed with no
if blocks to exclude them if they're not relevant. This makes it very
easy to accidentally rely on a Kconfig default set by a totally
different and not applying architecture.

This patch moves a few Kconfigs from ARM and X86 that leaked out like
this into a common Kconfig file for clarity. It also gives ARM64 its
own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one
(currently not used by any board).

In the future, we should maybe prefix all options in the arch/*/Kconfig
files with the architecture name (such as X86_BOOTBLOCK_NORMAL and
ARM_LPAE are already doing), to make it more apparent when they are used
in the wrong place.

BUG=None
TEST=None (tested together with dependent changes)

9ef9d85976 bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.

In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

a63719407f x86 cache-as-ram: Remove BROKEN_CAR_MIGRATE option
This was added to handle cases of Intel FSP platforms that had
EARLY_CBMEM_INIT but could not migrate CAR variables to CBMEM.
These boards were recently fixed.

To support combination of EARLY_CBMEM_INIT without CAR migration was
added maintenance effort with little benefits. You had no CBMEM
console for romstage and the few timestamps you could store were
circulated via PCI scratchpads or CMOS nvram.

77b1655d9b vboot2: add verstage
This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.

Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.

TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.
BUG=None

d6865222c8 misc: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.

Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)

This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.

Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.
