2013-03-08am33xx: Update DDR3 EMIF configuration sequenceTom Rini
Based on http://processors.wiki.ti.com/index.php/AM335x_EMIF_Configuration_tips we need to re-work our sequence in config_sdram slightly to match what the TRM describes as the correct sequence. In our current (incorrect) sequence some edge cases may fail to initalize correctly. Signed-off-by: Tom Rini <trini@ti.com>

2013-01-09mx6: Add workaround for ARM errataFabio Estevam
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>
2013-01-08arm: move C runtime setup code in crt0.SAlbert ARIBAUD
Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2012-11-19arm: Add control over cachability of memory regionsSimon Glass
Add support for adjusting the L1 cache behavior by updating the MMU configuration. The mmu_set_region_dcache_behaviour() function allows drivers to make these changes after the MMU is set up. It is implemented only for ARMv7 at present. This is needed for LCD support, where we want to make the LCD frame buffer write-through (or off) rather than write-back.

The mx5 lowlevel_init.S contains board-specific code based on the reference design. Let's keep it since it avoids creating new lowlevel_init files and it may be used by many boards.
