69 * We need to sacrifice first 4 bytes of RAM here to avoid triggering some
70 * strange BUG in ROM corrupting first 4 bytes of RAM when loading U-Boot
71 * binary. In case there was more of this mess, 0x100 bytes are skipped.
73 * In case of a HAB boot, we cannot for some weird reason use the first 4KiB
74 * of DRAM when loading. Moreover, we use the first 4 KiB for IVT and CST
75 * blocks, thus U-Boot starts at offset +8 KiB of DRAM start.
77 * As for the SPL, we must avoid the first 4 KiB as well, but we load the
78 * IVT and CST to 0x8000, so we don't need to waste the subsequent 4 KiB.
