* ata: ahci: refactor init functionsSascha Hauer2013-03-081-78/+58
| | | | | | Fold ahci_host_init and __ahci_host_init into ahci_add_host Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ata: ahci: implement init callbackSascha Hauer2013-03-082-39/+30
| | | | | | | | Now that we have framework support for delayed probing of ata devices implement it in the ahci driver to actually make use of it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ata: add ata logical device to defer probeSascha Hauer2013-03-081-8/+49
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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>

* x86 ATA: Don't touch the size entry for the BIOS disk based deviceJuergen Beisert2011-03-101-1/+0
| | | | | | | Only the platform sets this entry to setup the correct size or signals the driver to guess the size of the attached disk. Signed-off-by: Juergen Beisert <jbe@pengutronix.de>
* Don't try to guess the size of a disk if its size value is already givenJuergen Beisert2010-10-111-9/+18
| | | | | | | | | | | | | | | | | Guessing the size of an attached harddisk (access via x86 BIOS) was needed due to the fact, barebox can't query this information from the BIOS easily. But with the SD/MMC cards, there will be a second user of the generic disk handling routines. And with this media it is very easy to know its size. This patch provides a workaround to keep the guessing feature if the size of the registered disk is 0. If it is not 0, the given value will be used instead. Note: This is in preparation to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Don't use a sector buffer on stackJuergen Beisert2010-10-111-5/+12
| | | | | | | | | | | | | | | Using a temp. buffer for a disk sector on the stack, seems not work. Doing so lets the system run crazy (the stack seems to be destroyd). Don't know the correct stack handling on ARM, but (IMHO) I also can exclude any writing across the buffer boundaries. Using a temp. buffer via malloc() runs also on ARM. Note: This patch was required to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Make the disk driver less noisyJuergen Beisert2010-10-111-1/+2
| | | | | | | | | | | | In real life this output is only a "nice to have", but most of the time its useless and confusing. So, make it a debug feature for the interested developer. Note: This is in preparation to add MCI card support, which mostly come with a partition table and can be handled like a disk drive.
