So you'd prefer an ioread8be() interface? Actually, ioread8be is unnecessary, but I was planning to add ioread16/ioread32 and iowritexx be on be variants (equivalent to _raw_readw et al.) After all, the driver must know the card is BE, so the routines that make use of the feature are easily coded into the card, so there's no real need to add it to the iomem cookie. Did anyone have a preference for the API? I was thinking ioread32_native, but ioread32be is fine too.
