There are least 3 that are relevant here:

- MPC850 microcode patch for relocating I2C/SPI parameters.
- MPC860 microcode patch for relocating I2C/SPI parameters
  (to be used with MPC823, MPC855, ... as well; yes, here the
  823 is NOT in the same group as the 850)
- MPC823 (and 850?) patch for automatic USB start-of-frame (SOF)
  token generation

Depending on the  processor  model  and  requirements  you  may  need
patches 1, 1+3, 2, 2+3, or 3.

They can (like in our CVS tree :-)

Of course this can be done.
