The differences from ARMv7-M NVIC are:
   * ARMv6-M only supports up to 32 external interrupts
    (configurable feature already). The ICTR is reserved.
   * Active Bit Register is reserved.
   * ARMv6-M supports 4 priority levels against 256 in ARMv7-M.

v2:
     * Added num_prio_bits field
     * AIRCR.PRIGROUP is set as RAZ/WI for Baseline

Applied to target-arm.for-3.1, thanks.

It seems like you applied the first version of this patch.
Can you check this, please?

Best regards, Julia Suvorova.
