Re: MPC823E SMC/I2C/SPI micropatch

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

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
