riscv: create a loader.bin boot image for Kendryte SoC (2020-04-03 10:50:17 -0700)
----------------------------------------------------------------
RISC-V Patches for the 5.7 Merge Window, Part 1
This tag contains the patches I'd like to target for 5.7. It has a handful of
new features:
* Partial support for the Kendryte K210. There are still a few outstanding
issues that I have patches for, but I don't actually have a board to test
them so they're not included yet.
* SBI v0.2 support.
* Fixes to support for building with LLVM-based toolchains. The resulting
images are known not to boot yet.
This builds and boots for me. There is one merge conflict, it's just a Kconfig
merge issue. I can publish a resolved branch if you'd like.
I don't anticipate a part two, but I'll probably have something early in the
RCs to finish up the K210 support.
