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.

Nico Huber d1cc812799 libpayload: Add comments on virtual pointers in lib_sysinfo
After another incident related to virtual pointers in lib_sysinfo (and
resulting confusion), I decided to put some comments on the matter into
the code.

Remember, we decided to always use virtual pointers in lib_sysinfo, but
it's not always obvious from the code, that they are.

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.
