QEMU support using RustSBI

Compile and run with:

cargo qemu

When running cargo qemu, the test kernel will build and run. Expected output should be:

xtask: mode: Debug

Run test kernel

Requirements

cargo-binutils and llvm-tools-preview are needed

cargo install cargo-binutils
rustup component add llvm-tools-preview

Run

Run with:

cargo test

It will run RustSBI-QEMU with a test kernel. The test kernel will test all SBI functions, its command emulation and other features. If it succeeds, there would be output like:

running 1 test
    Finished dev [unoptimized + debuginfo] target(s) in 0.14s
   Compiling test-kernel v0.1.0 (D:\RustProjects\rustsbi-qemu\test-kernel)
    Finished dev [unoptimized + debuginfo] target(s) in 0.61s
test run_test_kernel ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 2.31s
