Looks like the NAND index is shadowed at 0xe3080 with entries in the following format:
(u64) offset, (u64) size, filename
A bit less noise in this thread would be nice though. It's cool that you want to help but if you can't resist the urge to post random bits you have found in the dump with absolutely no idea what they might be doing please at least don't ask if that could help enable <cool feature XY> - most of the time it won't.
And if you don't even know what PPC assembler is supposed to look like please don't bother installing IDA and toying around with the dump - that certainly won't lead to any significant insights.
I really don't want to sound arrogant but it would be a shame if the relevant info in this thread is buried under loads of wild but ultimately irrelevant guesses.
