IOMUX in tz_vmm

I assume you're trying to activate the TZASC of the i.mx6. I've had some
issues with this myself. In the end I never really managed to make it work
using the IOMUX (it also stopped executing when I tried to change the Gpr9
register) but it's possible to enable it using fuse programming. If you are
actually trying to enable the TZASC and are willing to blow a fuse to do so
you can execute "fuse prog 0 6 0x10000000" in uboot.
and the fusemap in the imx6 reference manual for some more info on the
This will blow the fuse and automatically enable the TZASC each time you
reset the board. I had to wait some time before my board really worked 100%
after executing that command so keep that in mind if something funky
happens right after blowing the fuse.

Best regards,
