hmm, they look the same to me: MPC850 Microcode Patch for Relocating I2C/SPI Parameters (06/10/2002), version 1.3
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").
