>ignoring it apparently has a bug limiting its actual view of all system ram on the higher capacity models
AFAIK that SoC had big and little DMA engines. The little engines can't reach the upper half of memory but the bigger ones can, which means you can just use the big DMA engines to muck with any RAM you yourself can't directly see. It's annoying for practical purposes but it doesn't have any security value.
