This patch is clearly incomplete because drivers/pcmcia/at91_cf.c does accesses AT91RM9200 specific SMC register, but the patch does nothing about making this work on AT91SAM9. Though it indeed seems that AT91SAM9 can be supported by that driver with minimum change -- perhaps by using cpi_is_*()...
Rather see latest patch on http://maxim.org.za/at91_26.html.
The cpu_is_XX() is for run-time selection (and is the preferred mechanism). Unfortunately the SMC registers are significantly different on the SAM9 and RM9200, so we need to use #ifdefs for compile-time selection.
Ah, seeing the real issue now: different encoding of the DBW fields b/w those 2 types of SMCs. Oh, and I've missed the different DBW field positions too... That however can be addressed by using the driver local #define', not the ones from the headers (which should be conflicting)...
