pflash change: https://github.com/spbrogan/edk2/pull/12

Logging change - I actually switched OVMF to use stdio since the log is captured either way and now it shows up in the web log output. https://github.com/spbrogan/edk2/pull/13

Do you have instructions for the cmdline for Qemu for Arm?  Is it something you would like to run?
