[U-Boot] [PATCH v3 0/8] riscv: Enable efi_loader support

[Alexander Graf]

We now have RISC-V support in U-Boot - which is great!

However, not that we're finally making progress to converge on
efi_loader and distro boot for booting on ARM platforms, we
really want to make sure there is no technical reason not to
do the same on RISC-V as well.

So this patch set introduces distro boot and efi_loader support
for RISC-V!

So far, I've only tested it with the selftest and hello world
target in U-Boot, as the number of target binaries to run is
still slim. But it should at least give us a good starting point.

v1 -> v2:

  - Allow 32bit target
  - Also save/restore ra, sp
  - Use edk2 default boot file names
  - Enable hello world binary
  - remove patch: efi_loader: selftest: Do not build relocation tests for risc-v
  - new patch: riscv: Add EFI application infrastructure

v2 -> v3:

  - Add missing crt0 source
  - Use official values for vci

Alexander Graf (8):
  riscv: Add setjmp/longjmp code
  riscv: Enable function sections
  riscv: Add EFI application infrastructure
  riscv: Add board_quiesce_devices stub
  efi_loader: Use EFI_CACHELINE_SIZE in the image loader too
  distro: Extend with RISC-V defines
  riscv: nx25: Enable distro boot
  efi_loader: Enable RISC-V support
