In general this is possible. However, as TrustZone is _no_
virtualization solution, it is not transparent to the non-secure guest
that it runs in the "normal world". So it is likely that you need to
first modify u-boot so it runs smoothly in the normal world. For
instance you have to check that it does not touch memory it does not
own, as well as devices. Moreover, u-boot should not try to access
system registers (coprocessor 15) that are TrustZone sensitive, like SCR
register.
