Rust crate deforest

Efficient #![no_std] parser for devicetree blobs compliant (hopefully) with version 0.4 of the specification.

The crate tries to be efficient by avoiding allocations (it can be used without alloc) and only iterating over nodes once, but I have no realistic benchmarks. On the downside, the interface isn't the most ergonomic.

Alternatives

• fdt-rs: can even build an index to interact with DTBs faster
• fdt: comes with extra types for a couple of common nodes

lib.rs:

Derive macro for deforest, a #![no_std] devicetree parser.
