This crate can be use in other projects that target different devices and should contain things like:

Wrappers around assembly to:
- do common operations: bkpt, wfi, enable/disable interrupts
- access CPU registers like lr, msp, etc.
Access to Cortex-M peripherals like NVIC, ITM, etc.
struct that represent common data structures like the vector table

Look at the x86 crate for inspiration.

cortex-m now exists.
