You would need a bootloader, since I doubt it uses UEFI an I'm not sure.
None of the drivers are probably supported, so you'll probably need to
write device drivers, everything from graphics to storage. By the time
you're done and have something workable, it will be so out of date it
will be a relic. Linux already supports a lot, and for embedded,
because of Android, the chipset makers have to have working linux
drivers to sell chips. Including getting the datasheets, it's outside
the scope of an independent developer. Now if you're Google and you
want to get rid of every vestige of GPL out of Android, it'll be ready
to ship by the end of the year, on ARM and amd64.
