| 6 | Select this option if you want to run EFI applications (like grub2) |
| 7 | on top of U-Boot. If this option is enabled, U-Boot will expose EFI |
| 8 | interfaces to a loaded EFI application, enabling it to reuse U-Boot's |
| 9 | device drivers. |

| 15 | help |
| 16 | Some hardware does not support DMA to full 64bit addresses. For this |
| 17 | hardware we can create a bounce buffer so that payloads don't have to |
| 18 | worry about platform details. |
