2014-04-02ahci: Fix data abort on multiple scsi resets.Roger Quadros
Commit 2faf5fb82ed6 introduced a regression that causes a data abort when running scsi init followed by scsi reset. There are 2 problems with the original commit 1) ALLOC_CACHE_ALIGN_BUFFER() allocates memory on the stack but is assigned to ataid[port] and used by other functions. 2) The function ata_scsiop_inquiry() tries to free memory which was never allocated on the heap. Fix these problems by using tmpid as a temporary cache aligned buffer. Allocate memory separately for ataid[port] and re-use it if required.

2014-04-02mmc: fsl_esdhc: fix calculation of timeout for data transactionsAndrew Gabbasov
Calculation of the timeout value should be based on actual clock value, written to controller registers. Since mmc->tran_speed is either the maximum allowed speed, or the preliminary value, that is be not yet set to registers, the actual timeout, taken by the controller, based on its clock settings, may be much longer than expected, based on mmc->tran_speed value. In particular it happens at early initialization stage, when typical value of mmc->tran_speed is 20MHz or 26MHz, while actual clock setting, configured in the controller, is 400kHz. It's more correct to use mmc->clock value for timeout calculation instead. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com> Acked-by: Pantelis Antoniou <panto@antoniou-consulting.com>

2014-03-31ARM: mxs: Add OCOTP driverMarek Vasut
Add yet another OCOTP driver for this i.MX family. This time, it's a driver for the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too different from the i.MX6 one that I could not use the mxc_ocotp.c driver without making it into a big pile of #ifdef . This driver implements the regular fuse command interface, but due to the IP blocks' limitation, we support only READ and PROG functions.

2014-03-24dfu: mmc: Replace calls to u-boot commands with native mmc APIŁukasz Majewski
For some time we have been using the run_command() with properly crafted string. Such approach turned to be unreliable and error prone. Switch to "native" mmc subsystem API would allow better type checking and shall improve speed. Also, it seems that this API is changing less often than u-boot commands.

2014-03-24mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou
The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

2014-03-23usb: dfu: introduce dfuMANIFEST stateHeiko Schocher
on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.

Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right thing, since if ec_command() returns a -ve number we will consider this be success. Adjust all comparisons to avoid this problem. This error was found with sandbox, which gives a segfault in this case. On ARM we may instead silently fail. We should also consider turning on -Wsign-compare to catch this sort of thing in future.
