* ehci-mxc: Fix host power mask bit for i.MX25Benoît Thébaudeau2012-11-19-1/+1
| | | | | | | | | | | | | The correct bit for H1_PM is 16, not 8, which is the DP pull-up impedance selection bit. This issue has been reported by Eric Bénard <eric@eukrea.com> and fixed by Christoph Fritz <chf.fritz@googlemail.com> on Linux, from which these #define-s had been copied.

* spi: mxc_spi: Fix spi clock glitch durant resetFabio Estevam2012-11-19-2/+2
| | | | | | | | | | | Measuring the spi clock line on a scope shows a 'glitch' during the reset of the spi. Fix this by toggling only the MXC_CSPICTRL_EN bit, so that the clock line becomes always stable. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>
* spi: mxc_spi: Fix handling of chip selectFabio Estevam2012-11-19-2/+3
| | | | | | | | | In decode_cs() function the polarity of the chip select must be taken into account. Also, for the case of low active chip select, the CS was activated too early. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* ehci-mx5/6: Make board_ehci_hcd_init() optionalBenoît Thébaudeau2012-11-16-3/+10
| | | | | | | | | | | | A custom board_ehci_hcd_init() may be unneeded, so add a weak default implementation doing nothing. By the way, use simple __weak from linux/compiler.h for board_ehci_hcd_postinit() instead of weak alias with full attribute.

| | | | | | | | | | Some MXC SoCs like the i.MX35 have hosts located at unusual offsets, so prepare to the introduction of i.MX35 support by defining the ehci-mxc hosts offsets at SoC level.

| * | | | usb gadget ether: Fix warning in is_eth_addr_valid()Tom Rini2012-11-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gadget ethernet driver needs to keep copies of the MAC address (at both endpoints) as strings so it needs a custom function for validation of the MAC. It was not however performing a totally correct check and also was emitting a warning about a set but unused variable. The solution to both is that after checking the string contents we use the standard test for a valid MAC.

This change allows supporting drives up to about 2TB. Testing this is a bit difficult. There is test code that can be inserted into U-Boot that will write test patterns into certain unused blocks. These patterns can be manually checked using 'dd' after boot. Another way is to confirm the original error that exposed this bug is fixed. IOW: see if AU (Auto Update) will now work on the drive. Also, check that there are no warning messages from the 'cgpt' utility. Signed-off-by: Walter Murphy <wmurphy@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

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.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | | 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).
