* mtd: Build nand_util.o for CONFIG_ENV_IS_IN_NAND in SPLTom Rini2014-04-17-0/+3

* mtd: Add a CONFIG_SPL_MTD_SUPPORT for a more full NAND subsystem in SPLTom Rini2014-04-17-27/+33
| | | | | | | | This mainly converts the am335x_spl_bch driver to the "normal" format which means a slight change to nand_info within the driver. Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Tom Rini <trini@ti.com>
* env_mmc.c: Remove NULL check on tmp_env1/2Tom Rini2014-04-17-6/+0
| | | | | | | With 452a272 we moved to allocating these variables on the stack. So they will never now be NULL so remove these checks. Signed-off-by: Tom Rini <trini@ti.com>
* env_mmc.c: Allow environment to be used within SPLTom Rini2014-04-17-8/+37
| | | | | | | | Inside of SPL we only concern ourself with one MMC device, so instead of being able to use CONFIG_SYS_MMC_ENV_DEV we need to use 0 in SPL. Switch the code to use a 'dev' variable to facilitate this. Signed-off-by: Tom Rini <trini@ti.com>
* fw_env.c: Switch get_config to use '%ms' in sscanfTom Rini2014-04-17-5/+8
| | | | | | | | | | We currently limit ourself to 16 characters for the device name to read the environment from. This is insufficient for /dev/mmcblk0boot1 to work for example. Switch to '%ms' which gives us a dynamically allocated buffer instead. We're short lived enough to not bother free()ing the buffer. Signed-off-by: Tom Rini <trini@ti.com>
* OMAP3: beagle-xm: generate fake USB ethernet MAC address from dieidNishanth Menon2014-04-17-0/+12
| | | | | | | | Similar to OMAP5uEVM, PandaBoard, BeagleBoard-XM has a USB based ethernet without MAC address embedded. So fake a MAC address following the similar strategy used on OMAP5 and PandaBoard family. Signed-off-by: Nishanth Menon <nm@ti.com>

* OMAP: common: consolidate fake USB ethernet MAC address creationNishanth Menon2014-04-17-32/+37
| | | | | | | | | | | | | | TI platforms such as OMAP5uevm, PandaBoard, use equivalent logic to generate fake USB MAC address from device unique DIE ID. Consolidate this to a generic location such that other TI platforms such as BeagleBoard-XM can also use the same. NOTE: at this point in time, I dont yet see a need for a generic dummy ethernet MAC address creation function, but if there is a need in the future, this can be further abstracted out.

* ARM: OMAP: replace custom sr32() by standard I/O accessorsWolfgang Denk2014-04-17-163/+205
| | | | | | | | | | | | | | | | | | Replace the custom bit manipulation function sr32() by standard I/O accessors. A major motivation for this cleanup was the fact, that a number of calls of that function resulted in 32 bit wide shift operations on u32 data, which according to the C-ISO/IEC-9899-Standard provokes undefined behaviour: 6.5.7 Bitwise shift operators ... If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behavior is undefined.

For instance, $ make tricoder_config all [ build complete ] ... modify include/configs/tricoder.h $ make spl/u-boot-spl.lds should be updated in this case, but it wasn't.

| * ahci: Fix data abort on multiple scsi resets.Roger Quadros2014-04-02-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
