Stefan Reinauer 642b1db733 Eliminate use of pointers in coreboot table
Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.

Aaron Durbin a09760eb45 libpayload: add x86 ROM variable MTRR support
On x86, coreboot may allocate a variable range MTRR for enabling caching
of the system ROM. Add the ability to parse this structure and add the
result to the sysinfo structure.

An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the sysinfo structure. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.

Aaron Durbin 5ca4f4119b libpayload: add support for vboot_handoff
The vboot_handoff structure needs to be parsed from the coreboot tables.
Add a placeholder in sysinfo as well as the ability to parse the
coreboot table entry concering the vboot_handoff structure.

Built with unified boot loader and ebuild changes. Can find and use
the VbInitParams for doing kernel selection.

Gabe Black d94512edee libpayload: Add CB_ prefixes to some constants in coreboot_tables.h.
This makes their names more consistent with other constants in this header,
avoids name collisions, and makes it more obvious where the names came from.

Gabe Black 025667f0ec libpayload: Change "GPIOs" into flags.
Some constants which were used to interpret the contents of the coreboot
tables were moved to the appropriate libpayload header file. The constant which
describes the maximum length of a GPIO name was renamed to have a CB_ prefix.
That makes it more obvious what sort of GPIO name it describes, and reduces the
change of a name collision. It also makes it more consistent with other names
in that header, although some other exceptions still exist.

That coreboot uses the IP checksum is an artifact, not a deliberate
requirement to be compatible with the Internet Protocole suite. Use
a wrapper to abstract the computation of coreboot's checksum.

Philip Prindeville 46404d75e4 Replace UNPACK_CB64 macro with inline
Having submitted a module based on coreboot to LKML for acceptance,
it was requested that fewer macros and more inlines be used (because
of their superior type-checking when performing pointer casts, etc).

This is the first of several changes to make the relevant parts of
coreboot comply to linux code standards.

Stefan Reinauer abc0c85516 Printing coreboot debug messages on VGA console is pretty much useless, since
initializing VGA happens pretty much as the last thing before starting the
payload. Hence, drop VGA console support, as we did in coreboot v3.

- Drop VGA and BTEXT console support. 
  Console is meant to be debugging only, and by the time graphics comes up
  99% of the risky stuff has already happened. Note: This patch does not remove
  hardware init but only the actual output functionality. 

  The ragexl driver needs some extra love, but that's for another day
- factor out die() and post()
- drop some leftover RAMBASE < 0x100000 checks.

Uwe Hermann fad8c2bd7c Various small consistency fixes (trivial):
- Use _FOO_H include guard format everywhere.

 - Add missing speaker.c prototypes to libpayload.h.

 - Consistently use short form u8/u16/u32 instead of uint8_t et. al.

 - kcofig: Use 'depends on' instead of 'depends', which seems deprecated.
