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

Ping? Looking forward to someone applying patches too :)

Hey,

Sorry for late reply but I was not able to review the patches due to
other important work and holiday season. Now I am taking a stab at it
and I hope that it will land soon in the GRUB git tree.

May I ask you to rebase the patch set on the latest upstream? Patch #9
does not apply. Additionally, git complain in the following way on the
patch #05: new blank line at EOF.

How to build this target? Where I can find compiler and binutils need
to build it?

Daniel

SiFive has a precompiled toolchain that I just use for testing:

  https://www.sifive.com/boards/

I'm sure your distro of choice may also have compilers available.
