description:
Import irisboot, yet another bootloader for pre-ARC sgimips machines.
This bootloader adds support for Personal IRIS 4D/25 (IP6),
Personal IRIS 4D/35 (IP12), and Indigo R3000 (IP12) etc. and
optionally supports R4000 Indy and Indigo R4000 (ARCS machine)
using standalone WD33C93 SCSI driver.
Submitted by Naruaki Etomi via PR port-sgimips/53539,
