I'll take the high road and avoid an easy april fools joke here.

In all seriousness, when the 52xx code for 2.4 was brought up, there
were a number of objections to the Motorola provided code, from it's
buggy to it being unacceptable crap.  Finally, 2.4 is about to enter a
"deep freeze", or so Marcelo intends at least, so I think it's out of
the question for the mainline.  I don't mind keeping the
linux-2.4-mpc5xxx tree up to date so others can pull for what they need,
but it's a dead end.

For 2.6, I think one of the following options needs to be done.
- Motorola code, cleaned up with input from the community (and the bits
  Linux just doesn't need, left out).
- Ignore the Motorola code, or since it's GPL (must be to be in the
  kernel, so I'm just making the assumption here...) use it as a guide
  for how things work to implement a clean Linux implementation of the
  code.   I know there's someone working on this (who pops up on
  #mklinux on freenode from time to time) but I don't know how far
  they've gotten.
