OK, I'll simply change the above to CONFIG_PPC then.

It does, the bug is in the uart IP which I don't think we ever plan on fixing, so 32 or 64-bit parts will have it for ever and ever ;)

It should be runtime selected, there should be no ifdefs here.

The ifdef wasn't strictly required; it just made it so gcc would
toss the errata code out of the irq handler for !PPC.  Anyway it
will be a moot point if I can somehow hide all the mess by snooping
serial_inp() traffic and deploying the errata fix from there....

Eww.

If it's not to be allowed in the main 8250 code (even for ppc builds
only), a custom handle_port sounds like a saner option.
