As it stands, the memory node in the u8540 Device Tree is ignored and memory is actually stipulated by the bootloader via ATAGS. ARM core architecture code then extracts the memory ATAG and inserts it into the Device Tree. In the u8540 the LittleKernel bootloader only stipulates 512MB of memory; however, the u8540 actually has 2GB. We're taking the responsibility to register the remainder from Device Tree here.
