* mx6: Add workaround for ARM errataFabio Estevam2013-01-09-0/+10
| | | | | | | | | | | | | | | | | | Add workaround for the following ARM errata: 743622 and 751472. The motivation for this change is the following kernel commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access secure registers), which removes the errata from multiplatform kernel. Since imx has been converted to multiplatform in the kernel, we need to apply such workarounds into the bootloader. Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel. Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad" document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

Also, even though the ROUND macro is already defined in common.h, the reason for redefining it in image.h is explained by Stefano Babic: "I will remark a previous comment - even if including common.h seems a good idea to avoid duplications, it makes tools like mkimage to depend on the selected board, because <board>_config must run. Even if this is not a problem for us u-boot developers, it becomes an issue when these tools are included in distros (like u-boot-tools in Ubuntu) and cannot be packaged."

| | | | | | | | | | | | | | | | | | | | | | commit c73368150 (pmic: Extend PMIC framework to support multiple instances of PMIC devices) introduced an extra 'retval' variable, but this is not necessary since we have already the variable 'ret' in place.

| | | | | | | | | | | | | | | | | | | | | | | | | | The on-board number of available usdhc devices is something board specific. The patch moves CONFIG_SYS_FSL_USDHC_NUM out of mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd board. To keep the default mmc device for environment same as before (usdhc3), it moves CONFIG_SYS_MMC_ENV_DEV out of mx6qsabre_common.h and changes it to 1 for mx6qsabresd.
