Hi,
I am trying to get some i2c devices (RTC, EEPROM) to run on an MPC8260
with kernel version 2.4.21.
I have seen some fragmented information in the kernel source
documentation and on this mailing list, but it's not clear to me what
parts I can use and what I have to write myself.
Could anyone tell me where and how to start?
Thanks,
Jos

I think you need i2c-core.c, i2c-dev.c, i2c-algo-8260.c and
a driver file that set's up (board specific) i2c port settings
and irq. I think there are examples in the denx tree.
(i2c-pm826.c)
This is more or less the standard thing to do:
check the denx tree.
