In the dtb of mainline linux: /* Will be filled by the bootloader */ memory@0 { device_type = "memory"; reg = <0 0 0>; }; In uboot I have: static struct mm_region bcm2711_mem_map[] = { { .virt = 0x00000000UL, .phys = 0x00000000UL, .size = 0xfe000000UL, .attrs = PTE_BLOCK_MEMTYPE(MT_NORMAL) | PTE_BLOCK_INNER_SHARE }, { .virt = 0xfc000000UL, .phys = 0xfc000000UL, .size = 0x03800000UL, .attrs = PTE_BLOCK_MEMTYPE(MT_DEVICE_NGNRNE) | PTE_BLOCK_NON_SHARE | PTE_BLOCK_PXN | PTE_BLOCK_UXN }, { /* List terminator */ 0, } }; But I dont know if uboot use that for filling the memory node. Booting the rpi4 with efi=debug give: EFI stub: Booting Linux Kernel...
