Right, that's when you use the CS package which is a bit of overkill
for an embedded system, especially when you want to put the root
filesystem on the flash card.
I was speaking about the "simple" IDE interface which you get with
the CONFIG_IDE_8xx_PCCARD config option (plus one of 8xx_PCCARD,
8xx_DIRECT, or EXT_DIRECT). In this case, Linux reads the memory
mapping from the PCMCIA controller registers.
