WIP: IPU and HDMI drivers for i.MX6

[Ulrich Grey]

Hello,

I don't know whether this is related to your HDMI patches.
After some hours compiling a port, running the new system, I got this panic:
#
panic: vm_radix_insert: key 1 is already present

cpuid = 3

KDB: enter: panic

[ thread pid 53491 tid 100695 ]

Stopped at      $d.7:   ldrb    r15, [r15, r15, ror r15]!

Please see file: http://ulrich-grey.de/dl/wq20150722.txt
for further information.
