83d9712e70 x86: Add queensbay fsp patch information in README.x86
The FSP release version 001 for Intel Queensbay has a bug which
could cause random endless loop during the FspInit call. This bug
was published by Intel although Intel did not describe any details.
Describe this information in the x86 doc so that U-Boot Queensbay
support is invulnerable.

3a1a18ff18 x86: Add support for Intel Minnowboard Max
This is a relatively low-cost x86 board in a small form factor. The main
peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800
series CPU. So far only the dual core 2GB variant is supported.

This uses the existing FSP support. Binary blobs are required to make this
board work. The microcode update is included as a patch (all 3000 lines of
it).

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.
