43d976edd0 Prevent NULL from ever pointing to some real code or data. (This was
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).

10c28a51bd Create two easy-to-use entry points in libprefix: install and
install_prealloc.  I *think* these will suffice for all the 16-bit
prefixes.

in base memory.

98ff29345e Created a bus/device API that allows for the ROM prefix to specify an
initial device, and will also allow for e.g. a device menu to be presented
to the user.
