commit e27bddff4b97 ("imx8m: Restrict usable memory to space below 4G boundary") tried to adjust the usable memory limits on a 4GB boundary.

ram_top is described as 'top address of RAM used by U-Boot' and we want to preserve that. This is defined as a phys_addr_t and unfortunately its size differs across architectures. This has lead us to a weird state where 32bit boards define it 'SZ_4GB - 1' and 64bit boards as 'SZ_4GB' unless it was otherwise defined.

Applied to u-boot/master, thanks!
