eea0f11278 x86: Add an option to enabling building a ROM file
Rather than requiring the Makefile to be modified, provide a build option to
enable the ROM to be built.

We cannot do this by default since it requires binary blobs. Without these
the build will fail.

cb3b2e62ca x86: Add an 'mtrr' command to list and adjust MTRRs
It is useful to be able to see the MTRR setup in U-Boot. Add a command
to list the state of the variable MTRR registers and allow them to be
changed.

Update the documentation to list some of the available commands.

This does not support fixed MTRRs as yet.
