address to which U-Boot has relocated itself
reloc off
relocation offset, difference between *relocaddr* and the text base
Build
bitness of the system
current eth
name of the active network device
IP addr
network address, value of the environment variable *ipaddr*
fdt_blob
address of U-Boot's own device tree, NULL if none
new_fdt
location of the relocated device tree
fdt_size
space reserved for relocated device space
lmb_dump_all
available memory and memory reservations
devicetree
source of the device-tree
arch_number
