Sam Protsenko 955575c8dc disk: efi: Correct backing up the MBR boot code ... In commit e163a931af ("cmd: gpt: backup boot code before writing MBR") there was added the procedure for storing old boot code when doing "gpt write". But instead of storing just backup code, the whole MBR was stored, and only specific fields were replaced further, keeping everything else intact. That's obviously not what we want. Fix the code to actually store only old boot code and zero out everything else. This fixes next testing case: => mmc write $loadaddr 0x0 0x7b => gpt write mmc 1 $partitions In case when $loadaddr address and further memory contains 0xff, the board was bricked (ROM-code probably didn't like partition entries that were clobbered with 0xff). With this patch applied, commands above don't brick the board.
