The OpenBlocks AX3-4 has a non-DT bootloader. It also comes with 1GB of soldered on RAM, and a DIMM slot for expansion. Unfortunately, atags_to_fdt() doesn't work in big-endian mode, so we see the following failure when attempting to boot a big-endian kernel: 686 slab pages 17 pages shared 0 pages swap cached [ pid ] uid tgid total_vm rss nr_ptes swapents oom_score_adj name Kernel panic - not syncing: Out of memory and no killable processes...

A similar failure will also occur if ARM_ATAG_DTB_COMPAT isn't selected. Fix this by setting a sane default (1 GB) in the dts file.
