[Buildroot] [PATCH v2 0/3] Add support for HiFive Unleashed board

[Mark Corbin]

Hello

I've regenerated the patches to add support for the SiFive HiFive
Unleashed board. I tried to add support for a 5.0 series kernel, but
couldn't get the system to boot. This needs further investigation,
so I've gone with my original plan to use the 4.20.17 kernel. I've
created a new github repository for the patched kernel. This will
eventually be deprecated in favour of a 5.0 or 5.1 series kernel.

Changes v1 -> v2:
  - moved generation of bbl binary file in riscv-pk.mk from
    INSTALL_CMDS to BUILD_CMDS (Arnout)
  - added new patch to modify riscv-pk build scripts to remove
    hardcoding of ABI.
  - removed the large kernel patch and replaced it with a custom
    git repository (Arnout)
  - reduced the kernel config fragment to a minimum (Arnout)
  - use a separate root filesystem instead of a linked-in
    initramfs image (Arnout)
  - changed naming convention from sifive-u540* to
    sifive_hifive* (Arnout)
  - added post-image script to generate a complete SD card image
    file (Arnout)
  - updated the default configuration to make use of compressed
    instructions and the lp64d ABI for builds.
  - updated the DEVELOPERS file.


Regards

Mark
