As part of the plan for total world domination, we would like to make sure
that booting on RISC-V is in a sane state before anyone goes and does quick
hacks "just because".

For that reason, U-Boot supports UEFI booting on RISC-V for a while now.
This patch set is the second part of the puzzle, with grub learning how to
deal with a UEFI enabled RISC-V target.

The third bit (still missing) is to actually make a working Linux UEFI port.
But that will come, I'm sure :).

Looking forward to review feedback and testing,

v1 -> v2:

  - adapt to new grub_open_file() API
  - adapt to new grub_create_loader_cmdline() API

v2 -> v3:

  - fix riscv32 target

v3 -> v4:

  - Rebase onto current git master
  - Change copyright from 2013 to 2018
  - Coding style fixes
  - Add spec reference
  - Resurrect time reading code

v4 -> v5:

  - Mark grub_arch_sync_dma_caches args as unused
  - Whitespace fix
  - Add spec link to mkimagexx.c
  - Remove curly braces
  - Use GRUB_EFI_LINUX_FDT_EXTRA_SPACE
  - Fix whitespace
  - s/failure/fail
  - Remove blank line at EOF
  - Add blank lines before and after license tag
  - New patch: RISC-V: Add libgcc helpers for clz

v5 -> v6:

  - Remove most linux loading logic

Alexander Graf (11):
  efi: Rename armxx to arch
  PE: Add RISC-V definitions
  elf.h: Add RISC-V definitions
  RISC-V: Add setjmp implementation
  RISC-V: Add early startup code
  RISC-V: Add Linux load logic
  RISC-V: Add awareness for RISC-V reloations
  RISC-V: Add auxiliary files
  RISC-V: Add libgcc helpers for clz
  RISC-V: Add to build system
  fdt: Treat device tree file type like ACPI

Successfully tested on the HiFive Unleashed.

Great! Thank you for testing GRUB on RISC-V.
