c6588c5af9 coreboot: introduce boot_device
The boot_device is a region_device that represents the
device from which coreboot retrieves and boots its stages.
The existing cbfs implementations use the boot_device as
the intermediary for accessing the CBFS region. Also,
there's currently only support for a read-only view of
the boot_device. i.e. one cannot write to the boot_device
using this view. However, a writable boot_device could
be added in the future.

1de648e272 CBMEM console: Fix buffer without EARLY_CBMEM_INIT
On S3 resume, CBMEM_ID_CONSOLE from previous boot is found in ramstage,
even when romstage did not create it. So buffer did not get cleared
on S3 resume path.

Also do not allocate for preram_cbmem_console in CAR when there
are no means to back it up to ram.

28d5ec9a7d x86: provide consistent cbmem_top() for CONFIG_LATE_CBMEM_INIT
For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is
called in ramstage to note the upper address of the 32-bit address
space. This in turn is consumed by cbmem. However, in this scenario
cbmem_top() cannot always be relied upon because get_top_of_ram()
doesn't return the same value provided to set_top_of_ram().
To fix the inconsistency in ramstage save the value passed in
to set_top_of_ram() and defer to it as the return value for
cbmem_top().

b890a1228d Remove address from GPLv2 headers
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.

eec8dfb5e7 build system: use archives, not linker action to shorten command lines
Intermediate linking may distort linker behavior (in particular related to
weak symbols). The idea is that archives are closer to 'just a list of
object files', and ideally makes the linker more predictable.

Using --whole-archive, the linker doesn't optimize out object files just
because their symbols were already provided by weak versions. However it
shouldn't be used for libgcc, because that one has some unexpected side-effects.

da3a146cae arm64: Make SPSR exception masking on EL2 transition explicit
The configuration of SPSR bits that mask processor exceptions is kinda
oddly hidden as an implict part of the transition() function right now.
It would be odd but not impossible for programs to want to be entered
with enabled exceptions, so let's move these bits to be explicitly set
by the caller like the rest of SPSR instead.

Also clear up some macro names. The SPSR[I] bit is currently defined as
SPSR_IRQ_ENABLE, which is particularly unfortunate since that bit
actually *disables* (masks) interrupts. The fact that there is an
additional SPSR_IRQ_MASK definition with the same value but a different
purpose doesn't really help. There's rarely a point to have all three of
xxx_SHIFT, xxx_MASK and xxx_VALUE macros for single-bit fields, so
simplify this to a single definition per bit. (Other macros in
lib_helpers.h should probably also be overhauled to conform, but I want
to wait and see how many of them really stay relevant after upcoming
changes first.)

This patch adds support for integrating the runtime-resident component
of ARM Trusted Firmware (github.com/ARM-software/arm-trusted-firmware)
called BL31. It expects the ARM TF source tree to be checked out under
$(top)/3rdparty/arm-trusted-firmware, which will be set up in a later
patch.

Also include optional support for VBOOT2 verification (pretty hacky for
now, since CBFSv1 is just around the corner and will make all this so
much better).

f1df50edf3 arm64: Reorganize payload entry code and related Kconfigs
Rename Kconfig options for secmon and spintable to be prefixed with
ARM64_ instead of ARCH_, which seems to be the standard throughout the
rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this
provides a clearer separation between generic options that are selected
by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to
some of the MAINBOARD_HAS_... we have) and options that only make sense
in the context of a single architecture.

a9ee61e253 cache: Add arch_program_segment_loaded call to arm and arm64
arch_program_segment_loaded ensures that the program segment loaded is
synced back from the cache to PoC. dcache_flush_all on arm64 does not
guarantee PoC in case of MP systems. Thus, it is important to track
and sync back all the required segments using
arch_program_segment_loaded. Use this function in rmodules as well
instead of cache_sync_instructions which guarantees sync upto PoC.

27ef602fab vboot: split class in library and stage
The build system includes a bunch of files into verstage that
also exist in romstage - generic drivers etc.
These create link time conflicts when trying to link both the
verstage copy and romstage copy together in a combined configuration,
so separate "stage" parts (that allow things to run) from "library" parts
(that contain the vboot specifics).
