works
Would be nice to be able to explicitly define addresses for the
romconfig variables, but I can't figure out how to make that
work. Instead, just explicitly load the files in teh right order to
make things land in the right places.

For some reason, the silly linker marks things in section .boot as
data rather than bss, so they'd end up initialized by default. Force
them to be NOLOAD so they preserve values across reboot so that boot
chaining works properly.

This shrinks the base OS load down a bit as well so that stm-flash
fits comfortably in the first 8kB of memory.
