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

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