10 * This driver supports the SATA controller of some Mavell SoC's.
11 * Here a (most likely incomplete) list of the supported SoC's:
16 * This driver implementation is an alternative to the already available
17 * driver via the "ide" commands interface (drivers/block/mvsata_ide.c).
18 * But this driver only supports PIO mode and as this new driver also
19 * supports transfer via DMA, its much faster.
21 * Please note, that the newer SoC's (e.g. Armada 38x) are not supported
22 * by this driver. As they have an AHCI compatible SATA controller
28 * Better error recovery
29 * No support for using PRDs (Thus max 64KB transfers)
31 * No port multiplier support
