Hi,
I am started with freescale LTIB but I decided to make a clone of Linus'
kernel tree mainly to have the latest and fixed mscan driver.
Linux is uncompressed and starts right, but when DIU driver probe function
is called (exactly when first framebuffer device is registered) linux
restarts. This behaviour repeats indefinitely.
(same behaviour with denx kernel tree).
I am using .dts that comes in the Linus’kernel tree. Maybe this .dts board
revision dependent?
I updated u-boot to with the denx one but similar results.
Maybe basic questions. Sorry for that.
Regards, Moises.

DIU support patch hasn't been merged yet, you can either
disable DIU frame buffer driver or use the DIU patch [1].

DTS in 2.6.34-rc1 is ok for DIU if you use the patch. Note
that you need to rebase it as it depends on USB support patches
which haven't been merged yet.
DIU frame buffer support is work in progress, it hopefully will
be included in 2.6.35.
