77 * We need to sacrifice first 4 bytes of RAM here to avoid triggering some

81 * In case of a HAB boot, we cannot for some weird reason use the first 4KiB
82 * of DRAM when loading. Moreover, we use the first 4 KiB for IVT and CST
83 * blocks, thus U-Boot starts at offset +8 KiB of DRAM start.
84 *
85 * As for the SPL, we must avoid the first 4 KiB as well, but we load the
86 * IVT and CST to 0x8000, so we don't need to waste the subsequent 4 KiB.
