Using ARM CMSIS in Zephyr

Piotr Mienkowski <piotr.mienkowski@...>

I should have asked this question some time ago. Most of the software out there in the wild which was developed for ARM Cortex-M processors is using CMSIS standard. In Zephyr we include core CMSIS files provided by ARM in ext/hal/cmsis folder however never use them.

Could someone who was there at the beginning shine more light on the following issues:
- What was the rationale to bypass CMSIS in Zephyr?
- What are the long term plans on using CMSIS?

Thanks and regards,
