* ahci: Fix 'Invaild' typoTaylor Hutt2012-11-02-1/+1

* ahci: Use sizeof(fis) instead of hardcoding '20'Taylor Hutt2012-11-02-5/+5
| | | | | | | | This cleanup replaces the hardcoded use of '20', which represents the number of bytes in the FIS, with sizeof(fis). Signed-off-by: Taylor Hutt <thutt@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* ahci: Make the AHCI code find the capacity of disks > 128 GB properlyGabe Black2012-11-02-5/+50
| | | | | | | | | | | | | | | | | | | | | | | In the structure returned by the ATA identify device command, there are two fields which describe the device capacity. One is a 32 bit data type which reports the number of sectors as a 28 bit LBA, and the other is a 64 bit data type which is for a 48 bit LBA. If the device doesn't support 48 bit LBAs, the small value is the only value with the correct size. If it supports more, if the number of sectors is small enough to fit into 28 bits, both fields reflect the correct value. If it's too large, the smaller field has 28 bits of 1s, 0xfffffff, and the other field has the correct value. The AHCI driver is implemented by attaching to the generic SCSI code and translating on the fly between SCSI binary data structures and AHCI data structures. It responds to requests to execute specific SCSI commands by executing the equivalent AHCI commands and then crafting a response which matches what a SCSI disk would send. The AHCI driver now considers both fields and chooses the correct one when implementing both the SCSI READ CAPACITY (10) and READ CAPACITY (16) commands.

* ahci: support scsi writing in AHCI driverHung-Te Lin2012-11-02-24/+30
| | | | | | | | | | | | | | | | | | The "scsi write" command requires support from underlying driver. This CL enables SCSI_WRITE10 in AHCI driver. Tested in U-Boot console, try to i/o with sector #64: scsi read 1000 40 1 md.b 1000 200 # check if things are not 0xcc mw.b 1000 cc 200 # try to fill with 0xcc scsi write 1000 40 1 mw.b 1000 0 200 # fill with zero md.b 1000 200 # should be all 0 scsi read 1000 40 1 md.b 1000 200 # should be all 0xcc Signed-off-by: Hung-Te Lin <hungte@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* ahci: Make sending the SETFEATURES_XFER command optionalGabe Black2012-11-02-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | This command doesn't really do anything when talking to a SATA device, and sending it confuses some of them. This change makes sending the command optional, and defaults to not. The situations where it should be sent are not the common case. With the standard SSD in the machine, here are some times with the option turned off: 1. 8277 2. 8273 3. 8050 And turned on: 1. 8303 2. 8155 3. 8276 Sending that command seems to have no meaningful effect on performance. This fixes problems with an SSD marked Toshiba NV6424, Taiwan 11159AE P and TC58NVG5D2FTA10.

* ahci: Optimise AHCI controller reset and start-upStefan Reinauer2012-11-02-9/+15
| | | | | | | | | | The existing code waits a whole second for the AHCI controller to reset. Instead, let's poll the status register to see if the reset has succeeded and return earlier if possible. This brings down the time for AHCI probing from 1s to 20ms. Signed-off-by: Stefan Reinauer <reinauer@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* ahci: Support splitting of read transactions into multiple chunksVadim Bendebury2012-11-02-29/+69
| | | | | | | | | | | | | With an Intel AHCI controller, the driver does not operate properly if the requested amount of blocks to read exceeds 255. It is probably possible to specify 0 as the block count and the driver will read 256 blocks, but it was decided to limit the number of blocks read at once to 128 (it should be a power of 2 for the optimal performance of solid state drives).

* remove unnecessary code in ata_piixPavel Herrmann2012-09-28-3/+0
| | | | | | | | | | We set sata_curr_device to 0 right after returning from init_sata(), so there's no point in setting it to the last scanned driver at this point. Note: there are more duplicities with cmd_sata, but those might be required, as the code seems to reset the entire controller on every scan, ignoring the requested port number.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
