Hello,
The PPC port makes a number of references to FirePower OpenFirmware
bugs. Is there a summary of the problems that were encountered
available?
For instance, am I correct in assuming that the function ofwr_init()
exists to get around a buggy firmware implementation that fails to
``save and restore the first location of each interrupt that it wants to
"take over".' [1]'?
Andrew
PS: As a suggestion, perhaps this might be an opportune moment to refine
the FIREPOWERBUGS option into several more specific cases.
