This is a very basic first cut at expanding registers with derivedFrom. This commit requires rust-embedded/svd#50
This removes any observable side effect of the --nightly switch by removing the use of unions and the untagged_unions feature gate. Unions are replaced with accessor functions that return the appropriate register block reference. Here's a playground link that shows that the pointer calculation looks reasonable: https://play.integer32.com/?version=stable&mode=debug&edition=2018&gist=cd56444abc03e6781e526bbddc7082bc This commit is a breaking change. This is based on this WIP PR branch: rust-embedded#256 It implements the easiest standalone portion of this issue: rust-embedded#218 and also makes accessing the unions "safe" too, which is requested here: rust-embedded#230

* Introduce a logging system. svd2rust now uses env_logger instead of printing directly to stderr. env_logger is currently configured to log messages >= info to stderr. * Fix import of logging macro. * Remove some noise in the generated code Struct initialisations don't need to repeat field names if they're equal to a local variable.
