IMHO, the 'b reset' and the 'nop nop nop' are two different issues, so
Helmut should create a formal patch for the 'b reset' issue right now,
which will fix mx31pdk (and maybe other boards) for the release. Then,
once the 'nop nop nop' issue has been resolved for TT-01 (cache issue
or something else), another formal patch should be created for this
issue, unless it is purely out of tree.

Albert, Fabio, what do you think?

Best regards,
