I understand that (at some point) we need to support part->size
uint64_t but the HEAD of u-boot [1],  u-boot-nand-flash/master [2] and
u-boot-nand-flash/next [3] have u32 for part->size. Changing this to
uint64_t would require reformatting the list_partitions size column as
a 64bit hex number -- as would treating the net_size there as a
uint64_t. This would be a change with impact of greater scope than
intended with this patchset.

I hope it will be acceptable to do the net_part_size return as uin64_t
and continue treating both the part->size and net_size as u32?
