| | | | | | | | Embedding struct ata_ioports into struct ide_port saves us an allocation. Making it available to client drivers is necessary to give them access to struct ata_port which is needed in the next patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* driver: Attach info callback to device, not to driverSascha Hauer2013-05-302-2/+2
| | | | | | | | Since the info is device specific and not driver specific, attach the callback to the device. This makes it possible to have a info callback for a device which does not have a driver attached. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | ata device usually take a long time to spin up, so it makes sense to only spend this time when the device is actually used. This adds a logical ata device and attaches a 'probe' parameter to it, similar to what MMC does. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | ata: Add i.MX AHCI driverSascha Hauer2012-12-073-0/+160
| | | | | | | | | | | | | | | | | | This adds the glue code for the i.MX SATA controller. This controller needs some i.MX specific setup and some SoC specific setting outside the controller itself. The code for setting up the correct clock source for the SATA phy has been taken from U-Boot. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ata: Add ahci supportSascha Hauer2012-12-074-0/+866
| | | | | | | | | | | | | | | | This adds ahci controller support based on U-Boot ahci support. Unlike U-Boot we do not push the SCSI layer in between, but use the ata interface directly. Tested on a Freescale i.MX53. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ata: Use dma_alloc for bufferSascha Hauer2012-12-071-1/+2

| | | | | | | | | | | | | | | | | | | | Currently we only support oldschool IDE SFF devices. This is done by registering a register layout struct and everything else is done by the generic IDE SFF driver. Since modern ATA devices still use ATA, but not the SFF interface anymore, split out the IDE SFF support to a separate file to allow for other types of ata interfaces.

* | ata: register disks as /dev/ata*Sascha Hauer2012-12-071-2/+4
| | | | | | | | | | | | | | | | | | Using /dev/disk* for every type of device is not helpful. It increases the chance that the user doesn't know which file corresponds to which device. So rename ata device files to /dev/ata*. Also add a dev_info about which device just has been registered. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Change byte order detection mechanism to kernel styleSascha Hauer2012-06-281-1/+1
| | | | | | | | | | | | | | | The Linux Kernel defines only one of __LITTLE_ENDIAN and __BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then be tested with #if __BYTE_ORDER == __xx_ENDIAN. As we tend to use a lot of Kernel code in barebox we switch to use the kernel way of determing the byte order. As this always causes a lot of confusion add a check to include/common.h to make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
