commit: https://git.buildroot.net/buildroot/commit/?id=58d7c712d7d1ef5b439ead455a4ed2ca659b60fb
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This commit adds a new package for a prebuilt bare-metal toolchain for
RISC-V 64-bit. Indeed, some bootloader/firmware for the BeagleV (and
potentially later for other platforms?) do not build with a
Linux-capable toolchain.
This uses a pre-built toolchain from SiFive, precompiled for x86-64,
so all packages using this toolchain must have the appropriate
BR2_HOSTARCH dependency.
This package is modeled after package/arm-gnu-a-toolchain/, which
package a pre-built ARM32 bare-metal toolchain.
