Description
I am trying to use svd2ada for the nrf52833.svd file which is in the nRF5_SDK_17.0.2_d674dde sdk package.
It generates a couple of warnings and then fails.
raised CONSTRAINT_ERROR : Invalid access value read-writeonce
I found the culprit, the nrf52833.svd uses lower case for the register access type and this fails here:
https://github.com/AdaCore/svd2ada/blob/861c829c994e5192081bcd742532a147a25a1289/src/base_types.adb#L270

Research direction
Start with src/base_types.adb around line 270, then run svd2ada against nrf52833.svd from nRF5_SDK_17.0.2_d674dde. Check how register access values are parsed and verify that the lowercase read-writeonce value no longer raises CONSTRAINT_ERROR during conversion.
