fdt

A pure-Rust #![no_std] crate for parsing Flattened Devicetrees, with the goal of having a very ergonomic and idiomatic API.

Example

```rust static MYFDT: &[u8] = includebytes!("../test.dtb");

fn main() { let fdt = fdt::Fdt::new(MY_FDT).unwrap();

println!("This is a devicetree representation of a {}", fdt.root().model());
println!("...which is compatible with at least: {}", fdt.root().compatible().first());
println!("...and has {} CPU(s)", fdt.cpus().count());
println!(
    "...and has at least one memory location at: {:#X}\n",
    fdt.memory().regions().next().unwrap().starting_address as usize
);

let chosen = fdt.chosen();
if let Some(bootargs) = chosen.bootargs() {
    println!("The bootargs are: {:?}", bootargs);
}

if let Some(stdout) = chosen.stdout() {
    println!("It would write stdout to: {}", stdout.name);
}

let soc = fdt.find_node("/soc");
println!("Does it have a `/soc` node? {}", if soc.is_some() { "yes" } else { "no" });
if let Some(soc) = soc {
    println!("...and it has the following children:");
    for child in soc.children() {
        println!("    {}", child.name);
    }
}
