[Buildroot] [PATCH 0/4] Support for the Beagle-V platform

Hello,
The beta version of the Beagle-V RISC-V 64-bit platform has been
showing up at the front door of a few lucky people around the world in
the past days.
As I happen to be one of those lucky people, the obvious first thing
to do was to get a Buildroot defconfig for this platform, and so 48
hours after receiving the board, this is what this patch series does.
This patch series is also available at:
https://github.com/tpetazzoni/buildroot/commits/beaglev
The first 3 patches are preparation patches for OpenSBI:
- Add support for version configuration, very much like we have for
the Linux kernel or U-Boot. Indeed, OpenSBI has platform-specific
code, so it is very likely that people will need to use a
non-upstream version.
- Add support for using U-Boot as an OpenSBI payload, as an
alternative to Linux.
- Add support for enabling/disabling the installation of different
OpenSBI image types, as the Beagle-V configuration doesn't build
the fw_jump and fw_dynamic images.
The final patch obviously adds the Beagle-V defconfig and related
files themselves. A slight annoyance is that the bootloader
pre-flashed on the board doesn't work as-is, just due to an incorrect
fdt_addr_r environment variable value. So reflashing the bootloader
with what has been built by Buildroot is necessary (but is trivial to
do using Xmodem).
And to conclude, the complete boot log:
bootloader version:210209-4547a8d
ddr 0x00000000, 1M test
ddr 0x00100000, 2M test
DDR clk 2133M,Version: 210302-5aea32f
0 crc flash: 06a62dd7, crc ddr: 06a62dd7
crc check PASSED
bootloader.
OpenSBI v0.9
