2 * op50n-rom.c -- configure GDB for an Oki op59n eval board.
13 * this array of registers need to match the indexes used by GDB. The
14 * whole reason this exists is cause the various ROM monitors use
15 * different strings than GDB does, and doesn't support all the
16 * registers either. So, typing "info reg sp" becomes a "r30".
