IBM 405GP

IBM 405GP

Has anyone been able to find any hardware based on IBM's 405GP core, and is
anyone working on a Linux variant for this core?

Most people anxious to get working on this are awaiting non-MMU-hobbled
405GP silicon (i.e. > Rev. 1). In the interim, progress is forging ahead
on the 403GC[X] port. Please see:

The 405GP is more or less functionally identical to the 403GCX with the
exception being that it has a slew of on-chip peripherals. The porting
work should really be focused on adding in support for those on-chip
peripherals. The other stuff (exception handling, MMU management, timer
code, etc) is mostly there already with the 403 port and should require
little, if any, modification to work with the 405GP.

I just received a 405GP system yesterday and expect to start working on it very
soon.  It is supposed to have a rev 2 405GP, but I haven't verified that yet.
