Add the Silicon Image series PCI Express to
Serial ATA controller support, including Sil3132,
Sil3131 and Sil3124.
The SATA controller can be used to load kernel.
The features list:
- Supports 1-lane 2.5 Gbit/s PCI Express
- Supports one/two/four independent Serial ATA channels
- Supports Serial ATA Generation 2 transfer rate of 3.0 Gbit/s
- Supports LBA28 and LBA48
