Hi

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

quoted

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

quoted

of scc ethernet and i2c. Does i2c work correctly without

the patch if

quoted

I don't use ethernet ?

I2C will work fine without I2C microcode patch if you don't
use ethernet on SCC1

Also, I submitted a new i2c-algo-8xx.c driver to this list
about 2 weeks ago. It contains
sevral bug fixes and improvements. It's not in linuxppc BK
yet, but I think it will be soon.
