- Use more #defines to make the code easier to read.
- Include some links to the reversed documentation.
- Avoid overlapping dt regions by changing the existing control@d800100
node to end before the OTP registers, with some bigger dt refactoring
left for a future series.

This Hollywood register isn’t properly understood, but can allow or

isn’t previously set correctly beforehand.
