2014-11-24cmd_sata: implement sata stop commandNikita Kiryanov
Implement sata stop command. This introduces the __sata_stop() weak function, which mirrors the weak __sata_initialize() function, giving users the option of undoing the custom steps performed in overrides of sata_initialize().

2014-11-24sata: implement reset_sata for dwc_ahsataNikita Kiryanov
Add reset_sata() to the sata driver interface and implement it for dwc_ahsata. This function cleans up after sata_init(), and therefore accepts a device number like sata_init() does. A dummy implementation is provided for the rest of the drivers. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Cc: Simon Glass <sjg@chromium.org> Cc: Stefano Babic <sbabic@denx.de>
2014-09-09sata: dwc_ahsata: implement sata_port_statusNikita Kiryanov
Define the new common function sata_port_status() which can be used to query the sata driver for the state of ports, and implement it for dwc_ahsata.

2012-10-15sata.h: Make all sata/ata drivers include <sata.h>Pavel Herrmann
- block_dev_desc_t says that block_(read|write) take lbaint_t for blkcnt not ulong. - We also move the extern of sata_dev_desc into <sata.h> - Remove now duplicate declarations from driver-specific headers.

2009-01-27SATA: do not auto-initialize during bootMike Frysinger
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().

2008-03-26ata: merge the ata_piix driverDave Liu
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. Signed-off-by: Dave Liu <daveliu@freescale.com>

2007-05-15Add driver for S-ATA-controller on Intel processors with Southmushtaq khan
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.
