* | efi_loader: Always flush in cache line size granularity | Alexander Graf | 2016-04-18 | -1/+9 |
| | | | | | | | | | | | | The cache line flush helpers only work properly when they get aligned start and end addresses. Round our flush range to cache line size. It's safe because we're guaranteed to flush within a single page which has the same cache attributes.

* | efi_loader: Add runtime services | Alexander Graf | 2016-03-15 | -0/+290 |
After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.
