Subject: console.rs: write entire strings without a loop
X-Git-Url: https://git.kitaultman.com/?a=commitdiff_plain;h=a915a2977f20b45de0a115e399113206a258f919;p=riscv_baremetal.git

console.rs: write entire strings without a loop

The MmioSerialPort already has a write_str() function, so there's no
need to loop the bytes.

Actually, given that MmioSerialPort also has a fmt::Write trait, it's
possible that we don't actually need to implement it for Console at all.
