To find the coreboot tables, the payload has historically searched for their
signature in a predefined region of memory. This is a little clumsy on x86,
but it works because you can assume certain regions are RAM. Also, there are
areas which are set aside for the firmware by convention. On x86 there's a
forwarding entry which goes in one of those fairly small conventional areas
and which points to the CBMEM area at the end of memory.
On ARM there aren't areas like that, so we've left out the forwarding entry and
gone directly to CBMEM. RAM may not start at the beginning of the address space
or go to its end, and that means there isn't really anywhere fixed you can put
the coreboot tables. That's meant that libpayload has to be configured on a
per board basis to know where to look for CBMEM.
Now that we have boards that don't have fixed amounts of memory, the location
of the end of RAM isn't fixed even on a per board level which means even that
workaround will no longer cut it.
This change makes coreboot pass the location of the coreboot tables to
libpayload using r0, the first argument register. That means we'll be able to
find them no matter where CBMEM is, and we can get rid of the per board search
ranges.
We can extend this mechanism to x86 as well, but there may be more
complications and it's less necessary there. It would be a good thing to do
eventually though.
BUG=None
TEST=Built and booted on nyan. Changed the size of memory and saw that the
payload could still find the coreboot tables where before it couldn't. Built
for pit, snow, and big.
BRANCH=None

The preceding patch copied gizmo2 from the amd/olivehill
board. This commit includes the changes required to make
the code reflect the gizmo2 hardware:
- Update the vendor Kconfig to add gizmo2
- Update the mainboard Kconfig
- Update devicetree
- Add support in for the soldered down DDR3
- Update the CODEC verb data
- Update the graphics connector settings
- Adjust the temperature thresholds for the fan
What's missing:
- Interrupt routing tables
Gizmo2 can boot DOS and Ubuntu 14.10.

- In '-ffreestanding' main() is just as any other function and so
it needs a type-signature. Fixes a clang warning.
- Bay Trail and Rangeley have the updated romstage.c with the code
moved into the chipset, put the prototype in romstage.c.
- The sandybridge code has not been updated, so the prototype
for it goes into chipset_fsp_util.h, next to the prototype for
romstage_main_continue.
- Correct the return value of baytrail main() from void * to void
and remove the unnecessary asmlinkage tag. I'm surprised that this
didn't generate a warning...
