With the implementation of the system reset controller we lost a setting
that is currently applied by the bootloader and which configures the IMP
port for 2Gb/sec, the default is 1Gb/sec. This is needed given the
number of ports and applications we expect to run so bring back that
setting.

I applied this, but I should have checked the Fixes: tag before pushing
it out as it's invalid. What tree did you get that SHA1-ID from? :-/
