Instead of tagging object files with .<class>, move them to a <class>
directory below $(obj)/. This way we can keep a 1:1 mapping between
source- and object-file names.
The 1:1 mapping is a prerequisite for Ada, where the compiler refuses
any other object-file name.
Tested by verifying that the resulting coreboot.rom files didn't change
for all of Jenkins' abuild configurations.

commit a8aef3ac (cbfs_spi: Initialize spi_flash when initializing
cbfs_cache) introduced a bug that makes the rarely-used unified
CBFS_CACHE() memlayout macro break when used in conjunction with
cbfs_spi.c (since that macro does not define a separate
postram_cbfs_cache region). This patch fixes the problem by making all
three region names always available for both the unified and split
macros in every stage (and adds code to ensure we don't reinitialize
the same buffer again in romstage, which might be a bad idea if
previous mappings are still in use).
BRANCH=None
BUG=None
TEST=Compiled for both kinds of macros, manually checked symbols in
disassembled stages.

Currently the CBFS mmap cannot be accessed at the beginning of romstage

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further

Bring rmodule linking into the common linking method.
The __rmodule_entry symbol was removed while using
a more common _start symbol. The rmodtool will honor
the entry point found within the ELF header. Add
ENV_RMODULE so that one can distinguish the environment
when generating linker scripts for rmodules. Lastly,
directly use program.ld for the rmodule.ld linker script.

There's no reason to have a separate verstage.ld now
that there is a unified stage linking strategy. Moreover
verstage support is throughout the code base as it is
so bring in those link script macros into the common

board/chipset needs to do in order to turn on verstage.

Though coreboot started as x86 only, the current approach to x86
linking is out of the norm with respect to other architectures.
To start alleviating that the way ramstage is linked is partially
unified. A new file, program.ld, was added to provide a common way
to link stages by deferring to per-stage architectural overrides.
The previous ramstage.ld is no longer required.
Note that this change doesn't handle RELOCATABLE_RAMSTAGE
because that is handled by rmodule.ld. Future convergence
can be achieved, but for the time being that's being left out.

In order to accommodate tracking timestamps in all the
__PRE_RAM__ stages (bootblock, verstage, romstage, etc)
of a platform one needs to provide a way to specify
a persistent region of SRAM or cache-as-ram to store
the timestamps until cbmem comes online. Provide that
infrastructure.

A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.
All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.
The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
allow multiple CBFS instances in the bootrom.
When the new option is enabled, the code running on the target
controls which CBFS instance is used. Since all other then header CBFS
structures use relative addressing, the only value which needs
explicit setting is the offset of the CBFS header in the bootrom.
This patch adds a facility to set the CBFS header offset. The offset
value of zero means default. i.e. the CBFS initialization code still
discovers the offset through the value saved at the top of the ROM.

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).
