Deviations from Risc-V spec about sp1

[pgrinaway]

It seems like this is actually allowed:

When an EEI does not
guarantee misaligned loads and stores are handled invisibly, the EEI must define if exceptions caused
by address misalignment result in a contained trap (allowing software running inside the execution
environment to handle the trap) or a fatal trap (terminating execution).

-p32 of the above linked spec (51 using the PDF file's numbering), which seems to suggest terminating on unaligned access is ok.

Yes. But you might want to document that somewhere.
