Title:
  MIPS Malta mini-bootloader print function has bad jump instruction

Status in QEMU:
  New

Bug description:
  One of the hardcoded bootloader library instructions in the MIPS Malta
  mini-bootloader's print function is:

  stl_raw(p++, 0x08000205);                                     /* j 814
  */

  Since this function is loaded at 0xbfc00808, this jump jumps to the
  middle of nowhere. The properly-encoded instruction is:

  stl_raw(p++, 0x0bf00205);                                     /* j 814
  */

  With this patch, the print function behaves as expected.
