The 'exception' command allows to test exception handling.
This implementation supports ARM, x86, RISC-V and the following exceptions:
- 'breakpoint' - prefetch abort exception (ARM 32bit only)
- 'unaligned' - data abort exception (ARM only)
- 'undefined' - undefined instruction exception

This needs something like Series-version: 2 (if you use patman) to set the version number in the header.
Did you look at using a uclass and driver, like sysreset?
