lpc55

Goals

• demystify the LPC55 ROM bootloader (at least for people who know Rust), by
  • modeling "protected flash" settings and other sparsely documented data as Rust types
  • implementing its protocol, removing leftover details for older chips
  • clarifying the cryptographic details
• unify
  • NXP's elftosb, blhost and spsdk projects
  • molejar's pyMBoot
  • ergonomic corresponding TOML-based config files
• library-first (independent of CLI), and an HTTP interface
• support for non-file based signing keys (via PKCS #11 URIs)
