* initial implementation for Tillitis TKey device * add UART implementation for TKey * add Pin interface implementation for TKey touch sensor * add RNG interface implementation for TKey * add helpful machine package functions to return identifiers such as name and version for TKey * use built-in timer for sleep timing on TKey * modify UART implementation for TKey to implement Serialer interface * implement BLAKE2s ROM function call for TKey device * handle abort by triggering TKey device fault using illegal instruction to halt CPU * simplify TKey implementation by inheriting from existing riscv32 target * return error for trying to configure invalid baudrates on UART * add tkey to builder test * be very specific for features passed to LLVM for specific config in use for TKey * handle feedback items from TKey device code review Signed-off-by: deadprogram <ron@hybridgroup.com>
