Crate pl011_drv

Driver for the pl011 UARTs in the QEMU implementation

This crate provides basic drivers for the UARTS exposed by QEMU. You can see the implementation of these uarts here

The QEMU target actually exposes 4 different UARTS, that can each be redirected to arbitary character devices or files. This crate allows those UARTS to be accessed in order to support more complicated use cases than can be provided by cortex_m_semihosting.
