I didn't see that patch, digging for unless ... bsp porting isn't an option.

I took a look into differences between imx_3.10.17_1.0.0_ga and
wandboard_imx_3.10.17_1.0.0_ga to get a picture what I have to hack to
port the bsp from 3.0.35 to 3.10.17 - but I miss the place where
previously platform initialization happened (arch/arm/mach-mx6/board-mx6q_sabresd.*)

Is there a suitable guide explaining bsp porting from imx_3.0.35_4.1.0 to
imx_3.10.17_1.0.0?

Cheers
