I've compiled U-Boot & Kernel with 3.4.2... the only thing that seems to
fail in this process (obscurely) is hello_world, whereas the rest of the
tree seems quite happy to compile *without* error/warning !

Granted.. U-Boot doesn't currently actually boot on my board, but,
/that's/ just a matter of time/proffering sacrifice to the gods of
SDRAM-UPM configuration. Easy !
