Bridge, ICH-5, ICH-6 and ICH-7. Implementation: 1. Code is divided in to two files. All functions, which are controller specific are kept in "drivers/ata_piix.c" file and functions, which are not controller specific, are kept in "common/cmd_sata.c" file. 2. Reading and Writing from the S-ATA drive is done using PIO method. 3. Driver can be configured for 48-bit addressing by defining macro CONFIG_LBA48, if this macro is not defined driver uses the 28-bit addressing. 4. S-ATA read function is hooked to the File system, commands like ext2ls and ext2load file can be used. This has been tested. 5. U-Boot command "SATA_init" is added, which initializes the S-ATA controller and identifies the S-ATA drives connected to it. 6. U-Boot command "sata" is added, which is used to read/write, print partition table and get info about the drives present. This I have implemented in same way as "ide" command is implemented in U-Boot. 7. This driver is for S-ATA in native mode. 8. This driver does not support the Native command queuing and Hot-plugging.
