SATA: do not auto-initialize during boot

2009-01-27T22:42:39+00:00

Rather than have the board code initialize SATA automatically during boot,
make the user manually run "sata init".  This brings the SATA subsystem in
line with common U-Boot policy.

Rather than having a dedicated weak function "is_sata_supported", people
can override sata_initialize() to do their weird board stuff.  Then they
can call the actual __sata_initialize().

ata: merge the ata_piix driver

2008-03-26T22:38:48+00:00

move the cmd_sata.c from common/ to drivers/ata_piix.c,
the cmd_sata.c have some part of ata_piix controller drivers.
consolidate the driver to have better framework.

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

2007-05-15T21:25:37+00:00

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.
