The sbi command should be able to detect it.

The command 'exception' can be used to test the handling of exceptions.
Currently the exception command only allows to create an illegal
instruction exception on RISC-V.
Provide a sub-command 'exception unaligned' to cause a misaligned load
address exception.
Adjust the online help for 'exception undefined'.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

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
