Add driver for S-ATA-controller on Intel processors with South
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.

Add driver for S-ATA-controller on Intel processors with South
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.
