No, they are fdifferent:

Using MPC850MC2.zip and  MPC860MC05.zip (both 01/22/2002) I get:

The differences are small, but nobody  was  willing/able  to  explain
details.  I don't know if you can access these, but if you can please
see  also  Moto  helpline  "Service  Requests"  1-54379501  ("I2C/SPI
relocation  ucode")  and 1-54027957 ("I2C/SPI/SMC MicroCode Patch for
MPC823E").
