This patch set aims to expose 32-bit RISC-V cpu to RV64 QEMU. Thus
qemu-system-riscv64 can directly boot a RV32 Linux.
This patch set has been tested with 6.9.0 Linux Image.
And add an avocado tuxrun test in tests/avocado.
v6:
Use TUXRUN test case instead of boot_linux_console
Add any32 and max32 cpu for RV64 QEMU
v5:
Rebase to master and add tags
v4:
Drop UL completely in PATCH v3 2/7, 4/7, 5/7.
Avocado: Add "if=none" to "-drive" option in QEMU command line
v3:
Rebase to the master branch
