* am33xx: Correct and expand comments on CONFIG_SPL_MAX_SIZETom Rini2013-08-281-1/+1
| | | | | | | | We had been allowing the max size to be larger than actually allowed by the ROM. Expand the commentary here to explain why we set these locations. Signed-off-by: Tom Rini <trini@ti.com>

* am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h>Tom Rini2013-06-061-0/+2
| | | | | | | | | | 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.

* am33xx: Correct NON_SECURE_SRAM_START/ENDTom Rini2013-06-041-2/+2
| | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP: Make omap_boot_parameters common across socsSRICHARAN R2013-05-101-25/+0
| | | | | | | | omap_boot_parameters is same and defined for each soc. So move this to a common place to reuse it across socs. Signed-off-by: Sricharan R <r.sricharan@ti.com>

* omap4/5/am33xx: Make lowlevel_init available to all armv7 platformsTom Rini2012-09-011-1/+0
| | | | | | | | | | | | | | Make the lowlevel_init function that these platforms have which just sets up the stack and calls a C function available to all armv7 platforms. As part of this we change some of the macros that are used to be more clear. Previously (except for am335x evm) we had been setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are equivalent to simply referencing NON_SECURE_SRAM_END. On am335x evm we should have been doing this initially and do now. Cc: Sricharan R <r.sricharan@ti.com> Tested-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Rini <trini@ti.com>
* ARM:AM33XX: Add SPL support for AM335X EVMChandan Nath2012-01-161-0/+59
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.
