Hi Wolfgang,
but then do you think if there's any way to use some generic read/write routines? The problem is we use ml509 board loaded with Synopsys DW ACR700 core and we need to access SystemACE CF-card controller (to boot Linux kernel mainly).
Or should I just add conditional branch for ARC architecture?
Regards, Alexey

And what if you use "__raw_writew"/"__raw_readw" instead?
I'd rather not try that, as the __raw_* functions are missing the memory barriers that are mandatory for such device access.
Best regards,
Wolfgang Denk
