More platforms are not able to hibernate under certain circumstances,
such as when AC is plugged. This original path was conservatively put in
to prevent potential damage when cr50-update-caused asynchronous resets
occur. Julius' compelling argument that async resets from recovery mode
requests should have enough coverage of the design over the course of
project development. Remove the hibernate path and assume all is well
going forward.

While during the read training itself only the settings for rank 0 are used for
all ranks, the controller does use the separate settings for each rank later on.
It is unknown which register is responsible for this.
The signals are probably not generated separately and therefore need to have the
same settings for all ranks. Therefore program the results for all ranks instead
of for all populated ranks.

With https://github.com/IntelFsp/FSP/pull/4 merged, this allows using
Intel's FSP repo (that we mirror) to build a complete BIOS ifd region
with a simple coreboot build, automatically drawing in headers and
binaries.
This commit covers Apollolake, Coffeelake, Skylake, and Kabylake.
Skylake is using Kabylake's FSP since its own is FSP 1.1 and Kabylake's
also supports Skylake.
Another candidate (given 3rdparty/fsp's content) is Denverton NS, but
it requires changes to coreboot's FSP bindings to become compatible.
Cannonlake, Whiskeylake require an FSP release.

The arm32 GDB architecture code contains a little hack that allows it to
(sort of) correctly deal with a reentrant exception triggered from
within the GDB stub. The main logic for this isn't really arm32 specific
and could be useful for other architectures as well, so factor it out
into a separate function.

This patch reworks the arm64 exception handling to be more similar to
how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state
structure and supporting the same sort of partial reentrancy that is
useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.
This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).
Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

Bounce buffers used to be used in those cases where the payload
might overlap coreboot.
Bounce buffers are a problem for rampayloads as they need malloc.
They are also an artifact of our x86 past before we had relocatable
ramstage; only x86, out of the 5 architectures we support, needs them;
currently they only seem to matter on the following chipsets:
src/northbridge/amd/amdfam10/Kconfig
src/northbridge/amd/lx/Kconfig
src/northbridge/via/vx900/Kconfig
src/soc/intel/fsp_baytrail/Kconfig
src/soc/intel/fsp_broadwell_de/Kconfig
The first three are obsolete or at least could be changed
to avoid the need to have bounce buffers.
The last two should change to no longer need them.
In any event they can be fixed or pegged to a release which supports
them.
For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the
value needed in 1999 for the 32-bit Linux kernel, the original ramstage)
to 0xe00000 (14 Mib) which will put the non-relocatable x86
ramstage out of the way of any reasonable payload until we can
get rid of it for good.
14 MiB was chosen after some discussion, but it does fit well:
o Fits in the 16 MiB cacheable range coreboot sets up by default
o Most small payloads are well under 14 MiB (even kernels!)
o Most large payloads get loaded at 16 MiB (especially kernels!)
With this change in place coreboot correctly still loads a bzImage payload.
Werner reports that the 0xe00000 setting works on his broadwell systems.
