Basically one thing is crucial: u-boot-v2 has no x86 support as we
speak. The architecture support would require some libgcc functions,
probably memcpy etc, a linker script and some Kconfig changes. There
could be a generic coreboot "board" with (almost) no hardware init.

The next thing is to get the amount of available RAM from the coreboot
table, a serial driver, etc. It might be worthwhile to consider linking
against libpayload for that, as it'll provide an UHCI stack, too.

After that, it would be interesting to look into flash drivers, to be
able to use ubootenv for variables, etc. Maybe CBFS support etc.
