Microcode patching

Hi all,

I've got a question regarding the mpc8xx microcode patches in
arch/ppc/8xx_io/micropatch.c. We do need usb host mode, i2c and
ethernet operation at the same time. As I understood, i can't load
the microcode patches for usb sof generation and iic/spi together,
because they "live" at the same address. Now my question: What occurs
if I don't load the ii2/spi patch. I do need the usb sof timing, but
does the i2c-Interface work without the iic/spi patch ? As I read on
the motorola webserver, the iic/spi is needed for concurrent operation
of scc ethernet and i2c. Does i2c work correctly without the patch if
I don't use ethernet ?

Greetings
