Massimo,

Take a look at the patch I posted a few days ago:
'Common names for MCF I2C'

Cheers,

I'm trying to compile uClinux-dist 2007-01-03 for my AvNet MCF5282 with kernel 2.6.x. When I compile the distribuition with i2c module for Motorola MCF5282 (i2c-mcf.c), I get compiler errors. 

Is the header file (i2c-mcf.h) an old version?
Have you some information about?

Similar problems on QSPI kernel module.

Thanks,
