After I did a new toolchain build, I found the
the mhartid register value is wrong for Spike.
The docs seem to agree with Spike, not the
code the toolchain produces?
Until such time as the bitstreams and toolchain can find
a way to agree, just hardcode it. We've been playing this game
for two years now so this is hardly a new approach.
This is intentionally ugly because we really need the
toolchains and emulators and bitstreams to sync up,
and that's not happening yet. Lowrisc
allegedly implements the v1.9 spec but it's PTEs are clearly
1.7. Once it all settles down we can just use constants
supplied by the toolchain.
I hope the syncup will have happened by the workshop in November.
This gets spike running again.

This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload,

is not complete so it just panics but ... it gets started.
We provide a standard payload function that takes a pointer argument
and makes the jump from machine to supervisor mode;
the days of kernels running in machine mode are over.
We do some small tweaks to the virtual memory code. We temporarily
disable two functions that won't work on some targets as register
numbers changed between 1.7 and 1.9. Once lowrisc catches up
we'll reenable them.
We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual

We now use the _stack and _estack from memlayout so we know where things are.

Implement postcar stage cbmem console support. The postcar stage
is more like ramstage in that RAM is already up. Therefore, in
order to make the cbmem console reinit flow work one needs the cbmem
init hook infrastructure in place and the cbmem recovery called.
This call is added to x86/postcar.c to achieve that. Additionally,
one needs to provide postcar stage cbmem init hook callbacks for
the cbmem console library to use. A few other places need to
become postcar stage aware so that the code paths are taken.
Lastly, since postcar is backed by ram indicate that to the
cbmem backing store.

the alignment is considered as size and covered by the MTRRs
ignoring the specified size.
In this case the callee has to make sure that the provided
size should be smaller or equal to the base address alignment
boundary.
To simplify this, utilize additonal MTRRs to cover the entire
size specified. We reuse the code from cpu/x86/mtrr/mtrr.c.

postcar_loader.c has a useful library of funtions for
setting up stack and MTRRs. Make it available in romstage
irrespective of CONFIG_POSTCAR_STAGE for use in stack setup
after Dram init.
The final step of moving the used and max MTRRs on to stack
is moved to a new function, that can be used outside of
postcar phase.

Switch the BL31 (ARM Trusted Firmware) format to payload so that it can
have multiple independent segments. This also requires disabling the region
check since SRAM is currently faulted by that check.
This has been tested with Rockchip's pending change:
https://chromium-review.googlesource.com/#/c/368592/3
with the patch mentioned on the bug at #13.

TEST=boot on gru and see that BL31 loads and runs. Im not sure if it is
correct though:

The field that was previously named 'efr' is actually the iommu feature
info field. The efr field is a 64-bit field that is only present in
type 11h or type 40h headers that follows the iommu feature info field.

The revision field was correct, but the comment was wrong. The revision
1 means that the IVRS table only uses fixed length device entries.
Update the field to use the IVRS revision #define.

Avoid the inclusion of a function declaration if the argument type
device_t is not defined.
This was not a problem until now because the
old declaration of device_t and the new one overlapped.
