This commit adds a re-implementation of hw/char/pl011.c in Rust.
How to build:
1. Configure a QEMU build with:
--enable-system --target-list=aarch64-softmmu --enable-rust
2. Launching a VM with qemu-system-aarch64 should use the Rust version
of the pl011 device

+# PL011 QEMU Device Model
+
+This library implements a device model for the PrimeCell® UART (PL011)
+device in QEMU.
+
+## Build static lib
+
+Host build target must be explicitly specified:
+
+```sh
+cargo build --target x86_64-unknown-linux-gnu
+```
+
+Replace host target triplet if necessary.
+
+## Generate Rust documentation
+
+To generate docs for this crate, including private items:
+
+```sh
+cargo doc --no-deps --document-private-items --target x86_64-unknown-linux-gnu
+```
+
+To include direct dependencies like `bilge` (bitmaps for register types):
+
+```sh
+cargo tree --depth 1 -e normal --prefix none \
+ | cut -d' ' -f1 \
+ | xargs printf -- '-p %s\n' \
+ | xargs cargo doc --no-deps --document-private-items --target x86_64-unknown-linux-gnu
