Script to allow rustc-only builds without cargo.
6 years ago
25ccdf6731
Update and cleanup makefile.
...
* Change few places from riscv64 to riscv32. Previously it was rv64
because the code author does not have a 32bit toolchain and used a
64bit one instead.
* Add new board type 'none', for running on qemu.
