mx6: Add workaround for ARM errata
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>
