2014-04-04arm: mxs: Add support for generating signed BootStreamMarek Vasut
This patch adds the groundwork for generating signed BootStream, which can be used by the HAB library in i.MX28. We are adding a new target, u-boot-signed.sb , since the process for generating regular non-signed BootStream is much easier. Moreover, the signed bootstream depends on external _proprietary_ _binary-only_ tool from Freescale called 'cst', which is available only under NDA. To make things even uglier, the CST or HAB mandates a kind-of circular dependency. The problem is, unlike the regular IVT, which is generated by mxsimage, the IVT for signed boot must be generated by hand here due to special demands of the CST. The U-Boot binary (or SPL binary) and IVT are then signed by the CST as a one block. But here is the problem. The size of the entire image (U-Boot, IVT, CST blocks) must be appended at the end of IVT. But the size of the entire image is not known until the CST has finished signing the U-Boot and IVT. We solve this by expecting the CST block to be always 3904B (which it is in case two files, U-Boot and the hand-made IVT, are signed in the CST block).

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.

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>

2014-04-01arm: mxs: Add serial console support into SPLMarek Vasut
Add support for serial console into the i.MX23/i.MX28 SPL. A full, uncrippled serial console support comes very helpful when debugging various spectacular hardware bringup issues early in the process. Because we do not use SPL framework, but have our own minimalistic SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not use preloader_console_init(), but instead use a similar function to start the console. Nonetheless, to avoid blowing up the size of the SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT is defined, which is disabled by default.
