Nope. Unfortunately, the line that made that clear didn't fall inside
the patch context:
[...]
#define SMC_inb(a, r) readb((a) + (r))
#define SMC_outb(v, a, r) writeb(v, (a) + (r))
#define SMC_insb(a, r, p, l) readsb((a) + (r), p, (l))
#define SMC_outsb(a, r, p, l) writesb((a) + (r), p, (l))
#elif defined(CONFIG_MACH_LOGICPD_PXA270) <====
#define SMC_CAN_USE_8BIT 0
#define SMC_CAN_USE_16BIT 1
#define SMC_CAN_USE_32BIT 0
#define SMC_IO_SHIFT 0
#define SMC_NOWAIT 1
#define SMC_USE_PXA_DMA 1
[...]
