ARM:AM33XX: Add SPL support for AM335X EVM This patch is added to support SPL feature on AM335X platform. In this patch, MMC1 is configured as boot device for SPL and support for other devices will be added in the next patch series.

am33xx: add ti814x specific register definitions Support the ti814x specific register definitions within arch-am33xx. Signed-off-by: Matt Porter <mporter@ti.com> Reviewed-by: Tom Rini <trini@ti.com> 2013-03-15 10:07:06 +00:00			`#ifdef CONFIG_AM33XX`
am33xx: Correct NON_SECURE_SRAM_START/END Prior to Sricharan's cleanup of the boot parameter saving code, we did not make use of NON_SECURE_SRAM_START on am33xx, so it wasn't a problem that the address was pointing to the middle of our running SPL. Correct to point to the base location of the download image area. Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being used. As part of correcting these tests, make use of the fact that we've always been placing our stack outside of the download image area (which is fine, once the downloaded image is run, ROM is gone) so correct the max size test to be the ROM defined top of the download area to where we link/load at.

am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h> The location of valid scratch space is dependent on SoC, so move that there. On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR. On am33xx/ti814x we want to use what the ROM defines as "public stack" which is the area after our defined download image space. Correct the comment about and location of CONFIG_SPL_TEXT_BASE.
