I've used the one in the linuxppc_2_4_devel tree with success.

Subject: MPC823E SMC/I2C/SPI micropatch
Hi,
we want to use SCCs and SMCs on our custom board
with MPC823E in following configuration:
Ethernets on SCC2 and SCC3,
UARTs on SMC2 and SMC1. Normally it is not possible,
because SCC3 ethernet parameter RAM overlaps SMC1 one.
I have found Motorola micropatch
for SMC/I2C/SPI relocation only for MPC850 and MPC860
processors. They are slightly different (exactly
these patches differ in one word). I would like
to ask if somebody tries to use one of them
for MPC823E. Or if another microcode patch exists
especially for MPC823E.
Regards, Jan Damborsky

Thank you. I will try it.

Hi,
I have found out that CPM micropatch
available in linux-2.4 from Wolfgang Denk
site (the kernel we use successfuly on our
custom boards at present) is applicable as well.
After some changes in 8xx CPM and UART code
I have succeeded.
For now, ethernets on SCC2 and SCC3, UARTs
on SMC1 and SMC2 work altogether.
Thank you very much.
Sincerely, Jan Damborsky
