On all TI platforms the ROM defines a "downloaded image" area at or near the start of SRAM which is followed by a reserved area. As it is at best bad form and at worst possibly harmful in corner cases to write in this reserved area, we stop doing that by adding in the define NON_SECURE_SRAM_IMG_END to say where the end of the downloaded image area is and make SRAM_SCRATCH_SPACE_ADDR be one kilobyte before this. At current we define the end of scratch space at 0x228 bytes past the start of scratch space this this gives us a lot of room to grow. As these scratch uses are non-optional today, all targets are modified to respect this boundary.
Tested on OMAP4 Pandaboard, OMAP3 Beagle xM
