b192df4d97 Fix ldscript for bootblock .rom section
Allocation size for the section was miscalculated, so the section
did not honour its upper-bound address.

Also align the section start to 4 bytes, so it starts with code
instead of pad bytes.

6a11333133 Drop eh_frame instead of moving it into the image.
That's what SeaBIOS does, too, and it works just fine.

52ffb2b66d Recently the 3 projects using the new AMD reference code have been
failing the check for globals (or statics) in romstage. This causes
ASRock E350M1, AMD Inagua, and AMD Persimmon builds to fail with the
message "Do not use global variables in romstage". The message is
working as intended. It is detecting data declared as 'static' when
'static const' was intended. The code executes correctly because it
never tries to modify the data.

To make reference code updates easy, it is probably best to avoid
modifying the AMD provided code if possible. The following change
bypasses the "Do not use global variables in romstage" check for
the AMD reference code only.

fab35e3f73 Move cmos.default handling to bootblock
The cmos.default code wasn't actually used so far, due to an oversight
when forward-porting this feature from an old branch.

- Extend walkcbfs' use by factoring out the stage handling into C code.
- New sanitize_cmos() function that looks if CMOS data is invalid and
  cmos.default exists and if so overwrites CMOS with cmos.default data.
- Use sanitize_cmos() in both bootblock implementations.
- Drop the need to reboot after writing CMOS: CMOS wasn't used so far,
  so we can go on without a reboot.
- Remove the restriction that cmos.default only works on CAR boards.
- Always build in cmos.default support on boards that
  USE_OPTION_TABLE.

0822ad8b19 This code fixes a number of build issues related to the AMD Agesa code. The particular issues are global variables existing in romstage and the use of GCC intrinsics in the build. The former issue will be addressed shortly, and the latter issue requires community assistance. This code is dependent on the AMD Family 14h mainboard code.
