selftests/nolibc: allow specify extra arguments for qemu
The opensbi package from Ubuntu 20.04 only provides rv64 firmwares:
$ dpkg -S opensbi | grep -E "fw_.*bin|fw_.*elf" | uniq
opensbi: /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_dynamic.bin
opensbi: /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.bin
opensbi: /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_dynamic.elf
opensbi: /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.elf
To run this nolibc test for rv32, users must build opensbi or download a
prebuilt one from qemu repository:
https://gitlab.com/qemu-project/qemu/-/blob/master/pc-bios/opensbi-riscv32-generic-fw_dynamic.bin
And then use -bios to tell qemu use it to avoid such failure:
$ qemu-system-riscv32 -display none -no-reboot -kernel /path/to/arch/riscv/boot/Image -serial stdio -M virt -append "console=ttyS0 panic=-1"
qemu-system-riscv32: Unable to load the RISC-V firmware "opensbi-riscv32-generic-fw_dynamic.bin"
To run from makefile, QEMU_ARGS_EXTRA is added to allow pass extra
arguments like -bios:
$ make run QEMU_ARGS_EXTRA="-bios /path/to/opensbi-riscv32-generic-fw_dynamic.bin" ...
