The only real concern I have right now is that this series, which is purely
x86, relies on functionality introduced in the "Add code to read in the
coreboot tables and	fill in memory info" series. Specifically,
install_e820_map() is in only in arch/x86/cpu/coreboot/sdram.c

Of course, you need to define CONFIG_ZBOOT_32 to make use of the
functionality, so maybe this is OK, but I do wonder if a default e829 map
is possible...

All that aside, I am going to have a good play with it all right now :)
