    TI: Rework SRAM definitions and maximums · fa2f81b0
    Tom Rini authored
    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.
