Memory dt node update introduced by spl_fixup_fdt() in below commit was making DDR configuration in-appropriate to boot falcon mode. Hence added dram_init_banksize for explicit assignment of proper base and size of DDR.
"boot: fdt: Perform arch_fixup_fdt() on the given device tree for falcon boot" (sha1: 6e7585bb64b12f632681c80c4b193349e1985d92)
