I've read that read[bwl]() and write[bwl]() are deprecated and
discouraged in new code and instead ioread{8,16,32}() and
iowrite{8,16,32}() should be used. Is this the case?
ioread/write should only be used when the code in question may have to
use either readl() or inl().
When a driver is written for hardware that is -always- used in MMIO
mode, then readl() is preferred, since its faster.
