This series includes various improvements which allow the mouse to be
used when running as an EFI app.

In particular:
- support for the absolute-pointer protocol, since this provides better
  integration when running under QEMU
- input tweaks to improve performance under QEMU

It also includes some x86-specific fixes for i8042 and MTRRs.

Finally, a new --bootcmd option is added to the build-qemu script to
allow passing a boot command to U-Boot.

This series is part F
