With 2a8e0fc nand_do_read_ops changed in behavior slightly (keeping in sync with the kernel which did this change in b64d39d8) such that the OOB data is always copied into oobbuf and never appended to datbuf. Within U-Boot only the nand_dump function (for the dump nand subcommand) was expecting the OOB data to only be appended to datbuf. So we now change nand_dump to not malloc extra space, correct the comment about datbuf and OOB data and switch the pointer to oobbuf before printing.
