why not using LLVM tools which are part of installed rust toolchain?
That's what Tock does.

For me, it looks like I always need to install something, either
apt install gcc-arm-none-eabiapt install llvmcargo install cargo-binutils && rustup component add llvm-tools(for callingcargo objcopy --)
In Tock, I find usage examples of options 1 and 2. So maybe the change in the latest commit is better?

I'm waiting for the documentation PR to #408 land, and then modify this PR to add its documentation to the right places. |

Rebase on top of the documentation changes, and added more context. |

This is the first PR containing the bootloader code. Compared to the full code, this PR misses the SHA256 computation using the Cryptocell.
It includes the full setup and infrastructure, including:
The bootloader directory is self-sufficient, it's basically independent from OpenSK. Therefore, I decided to give it its own
rust-toolchainfile. They currently run with the same toolchain for convenience, but an OpenSK toolchain upgrade should not necessarily burden is with also upgrading the bootloader toolchain (even though we can, of course).
