| 10 | Select this option if you want to run EFI applications (like grub2) |
| 11 | on top of U-Boot. If this option is enabled, U-Boot will expose EFI |
| 12 | interfaces to a loaded EFI application, enabling it to reuse U-Boot's |
| 13 | device drivers. |

| 20 | Some hardware does not support DMA to full 64bit addresses. For this |
| 21 | hardware we can create a bounce buffer so that payloads don't have to |
| 22 | worry about platform details. |
