  3. Subject: sunxi: sysupgrade: sync with x86
  4. sunxi sysupgrade was based on the x86 implementation; sync fixes and other
  5. changes from the current x86 version:
  6. x86: fix sysupgrades on disks with 4k block size
  7. x86: sysupgrade: move partition table change check to platform_check_image
  8. x86: sysupgrade: refactor platform_do_upgrade
  9. x86: sysupgrade: explicitly rescan disk after writing partition table
  10. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
