This patch enables the usage of the MVEBU AHCI/SATA driver. The only changes necessary to support MIPS Octeon via DT based probing are, to add the compatible DT property and the use of dev_remap_addr() so that the correct mapped address is used in the Octeon case (phys != virt). Please note that this driver supports the usage of the "scsi" command and not the "sata" command, since it does not provide an own "scan" function, which is needed for the "sata" cmd support.
