/*
* \brief Minimal AHCI-ATA driver
* \author Sebastian Sumpf <Sebastian.Sumpf@genode-labs.com>
* \date 2011-08-10
*
* This driver currently supports only one command slot, one FIS, and one PRD
* per FIS, thus limiting the request size to 4MB per request. Since the packet
* interface currently only supports a synchronous mode of operation the above
* limitations seems reasonable.
