#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.

omap-common: Common boot code OMAP3 support and cleanup This introduces OMAP3 support for the common omap boot code, as well as a major cleanup of the common omap boot code. First, the omap_boot_parameters structure becomes platform-specific, since its definition differs a bit across omap platforms. The offsets are removed as well since it is U-Boot's coding style to use structures for mapping such kind of data (in the sense that it is similar to registers). It is correct to assume that romcode structure encoding is the same as U-Boot, given the description of these structures in the TRMs. The original address provided by the bootrom is passed to the U-Boot binary instead of a duplicate of the structure stored in global data. This allows to have only the relevant (boot device and mode) information stored in global data. It is also expected that the address where the bootrom stores that information is not overridden by the U-Boot SPL or U-Boot. The save_omap_boot_params is expected to handle all special cases where the data provided by the bootrom cannot be used as-is, so that spl_boot_device and spl_boot_mode only return the data from global data. All of this is only relevant when the U-Boot SPL is used. In cases it is not, save_boot_params should fallback to its weak (or board-specific) definition. save_omap_boot_params should not be called in that context either.
