soc/cores/hyperbus: Full rewrite of HyperRAM core.
...
Rewriting the HyperRAM core to improve its design and functionality. The
old core grew complex over time without a clear structure. This new version
offers:
- IO registers on all signals for better performance.
- Flexible clocking options.
- Simplified architecture.
- Easier to extend with new features.
This rewrite provides a base for future development.

json2dts_zephyr: omit disable handler
...
omit disable handler for the sdcard peripherals,
as they still don't have a driver in zephyr and are not in the board dts.
This way the build in zephyr will not fail.
