 * U-Boot full is now encapsulated within a decompressing piggy.
 * u-boot-piggy loads at sram + 0x0, jumped to from the bootrom.
 * In the bootloader stage1 (piggy), the start of sram is text, data, bss,
 * with the piggy stack at the end of sram.
 * u-boot-piggy will decompress u-boot-full into the stage2 offset, since
 * the piggy cannot overwrite it's own text or data during decompression.
 * Once decompressed, piggy will jump to u-boot full. U-boot full will use
 * the sram previously occupied by the piggy text/data/bss as stack + heap.
 *
 * Piggy: SRAM: [text, data, bss, <--gap-->, stack, muc_stack, crumbs, <--gap-->]
 * Decompresses u-boot-full into second gap right after muc_stack and crumbs, jumps to gap.
 * Full:  SRAM: [heap, stack, <--unused-->, muc_stack, crumbs, text, data, bss]
