Hello,
 
can you tell me if NSSP is free to use on older and newer boards ? Is it the same port as the MMC on older boards ?
Are they currently occupied by any drivers (of the kernel) or can i just access the ports like pxaregs ? Or is there any easier way ? I haven't found /dev/spi (at least on my old image)...
 
Has someone a full description of the NSSCR1 register ? It looks like Intel document only describes Bits 31 to 22, but detail table for bits 21 to 0 is missing :-(
 
Regards,
