Michael Cardell Widerkrantz	c126199a41	fw: UDS not byte-readable ... Since UDS is not byte-readable we copy it by word to local_uds. Now UDS lives for a short while in local_uds on the stack in FW_RAM and in the internal buffer of the blake2s context (also in FW_RAM) but is very soon overwritten.	2023-03-27 16:24:02 +02:00

Michael Cardell Widerkrantz	c443ef8a3e	fw: clang-tidy and splint: New make target: check ... Add clang-tidy and splint static analytics check. For now, we use only the cert-* warnings on clang-tidy and run splint with a lot of flags to allow more things. Changes to silence these analytics: - Stop returning stuff from our debug print functions. We don't check them anyway and we don't have any way of detecting transmission failure. - Declare more things static that isn't used outside of a file. - Change types to be more consistent, typically to size_t or something or to uint32_t.	2023-03-22 11:05:32 +01:00
