| H A D | sdhci.h | c9fddbc4 Sun Dec 02 12:52:11 CST 2007 Pierre Ossman <drzeus@drzeus.cx> sdhci: use PIO when DMA can't satisfy the request
Some controllers have been designed on the assumption that all transfers
will be 32-bit aligned, both in start address and in size. This is not a

Revert back to PIO for individual requests in order to work around the
hardware bug.
