70 * This array of registers needs to match the indexes used by GDB. The
71 * whole reason this exists is because the various ROM monitors use
72 * different names than GDB does, and don't support all the
73 * registers either. So, typing "info reg sp" becomes an "A7".

86 * strings. We also need a CR or LF on the end.
