[Question] How do I do to secure LCD on L4 Linux ?

Hi, l4hackers 

I'm try to securing LCD on L4 Linux using Freescale i.MX6Q SABRESD
board.
I succeeded in securing Ethernet on L4 Linux.
But I don't yet secure LCD on L4 Linux.

LCD(HSD100PXN1) is connected by LVDS.
I've modified as below..

1.' .io'
I've added LDB control register address to '.io' file. 

2. 'mach_setup.c'
(l4linux/arch/l4/kernel/arch-arm/mach_setup.c)
I've added code for LVDS.

Qusetion 1. Did I do wrong modification  ?
Qusetion 2. Must I do something outside of that ? 

How do I do to secure LCD on L4 Linux ? 

If you give a bit hints me, I would appreciate it .
