* ahci: Perform SATA flush after disk write.Marc Jones2012-11-02-1/+54
| | | | | | | | | | Writes in u-boot are so rare, and the logic to know when is the last write and do a flush only there is sufficiently difficult. Just do a flush after every write. This incurs, usually, one extra flush when the rare writes do happen. Signed-off-by: Marc Jones <marc.jones@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* ahci: Adjust SATA timeouts for hard disk (spinup delay & command timeout)Walter Murphy2012-11-02-4/+10
| | | | | | | | | | | | | | | Note: These are timeout values and not delay values, so the event being timed out will complete whenever it is actually ready, with a measurement granularity of 1 millisecond, up till the timeout value. Therefore, there is no effect on SSD booting. The values were determined by instrumenting the code and measuring the actual time taken by several different models of HDD for each of the parameters and then adding 50% more for the spinup value and just doubling the command timeout value.

* ahci: flush / invalidate dcache around SATA commandsTaylor Hutt2012-11-02-0/+39

* ahci: Use virt_to_phys() to denote physical addresses for DMATaylor Hutt2012-11-02-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Update the assignment of various physical memory buffers used by the SATA controller to explicitly be denoted as physical addresses. The memory is identity-mapped, so these function calls are a nop, but they provide good semantic documentation for any maintainers. The return value of virt_to_phys() is 'unsigned long'. On machines where sizeof(unsigned long) != sizeof(pointer), a cast through (uintptr_t) is needed to appease the compiler due to the potential of losing the upper 32 bits of the address. In compilation this scenario, a physical address could be 64-bits, yet the C pointer environment only allows 32-bit addresses; the constraint is that pointers cannot address more than 4Gb of memory and if virt_to_phys() ever returns an out-of-range value for the physical address, there are issues with emmory mapping which must be solved. However, since the memory is identify mappeed, there is no problem introducing the cast: the original pointer will reside in 32-bits, so the physical address will also be within in 32-bits.

* ahci: Make the AHCI code find the capacity of disks > 128 GB properlyGabe Black2012-11-02-5/+52
| | | | | | | | | | | | | | | | | | | | | | | 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: 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.

| | | | | | | | | | 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.

* scsi: Provide support for a list of AHCI controllers.Vadim Bendebury2012-11-02-5/+35
| | | | | | | | | | | | | | | | | Many AHCI controllers are identical, the main (and often the only) difference being the PCI Vendor ID/Device ID combination reported by the device. This change allows the config file to define a list of PCI vendor ID/device ID pairs. The driver would scan the list and initialize the first device it finds. No actual multiple device list is introduced yet, this change just add the framework.

| | | | | | | | | | | | | 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).

* Add board_name to CONFIG_ENV_VARS_UBOOT_CONFIGStephen Warren2012-11-02-0/+1
| | | | | | | | | | | | | | CONFIG_ENV_VARS_UBOOT_CONFIG creates environment variables indicating which configuration U-Boot was built for. Some U-Boot binaries run on multiple boards, and hence this information may not uniquley describe the HW that U-Boot is actually running on. Another patch introduces environment variable board_name to represent that. In order to avoid scripts having to check $board_name, use it if set, and then fall back to using $board, make CONFIG_ENV_VARS_UBOOT_CONFIG also set a default value for board_name, so that variable is always available.

This makes sense in a real OS where a NULL pointer must never be dereferenced, but this is a bootloader, and there are cases where accessing the data at address null makes perfect sense.

* fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}Stephen Warren2012-10-29-13/+38
| | | | | | | | | | | | | | | | | | This makes the FAT and ext4 filesystem implementations build if CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the filesystems to be built separately from the filesystem-specific commands that use them. This paves the way for the creation of filesystem-generic commands that used the filesystems, without requiring the filesystem- specific commands. Minor documentation changes are made for this change. The new config options are automatically selected by the old config options to retain backwards-compatibility.
