* config/mn10300/tm-mn10300.h (REGISTER_SIZE,
MAX_REGISTER_RAW_SIZE, REGISTER_VIRTUAL_TYPE, REGISTER_BYTE,
REGISTER_VIRTUAL_SIZE, REGISTER_RAW_SIZE): Disable.
* mn10300-tdep.c (mn10300_do_registers_info,
mn10300_print_register): New functions. Pretty print registers.
(mn10300_register_virtual_type, mn10300_register_byte,
mn10300_register_virtual_size, mn10300_register_raw_size): New
functions.
(mn10300_gdbarch_init): Update.
* mn10300-tdep.c (mn10300_gdbarch_init): Check for mn10300 variant
and not mips variant in the info struct.
