+EDIT 2010-07-01: in common/cmd_ide.c, having CONFIG_PXA_PCMCIA defined
+would cause looping on inw()/outw() rather than using insw()/outsw(),
+thus making sure IDE / ATA bytes are properly swapped. This behaviour
+is now controlled by CONFIG_IDE_SWAP_IO, therefore PXA boards with
+PCMCIA should #define CONFIG_IDE_SWAP_IO.
