We have almost all pieces needed to support RISC-V UEFI binaries in place already. The only missing piece are ELF relocations for runtime code and data. This patch adds respective support in the linker script and the runtime relocation code. It also allows users to enable the EFI_LOADER configuration switch on RISC-V platforms.

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.

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.
