I'm using the SEIKO 4.3" WVGA touchscreen display on an i.MX6 board. I'm using the SabreSD development board and connects through an LCD expansion connector. The board is running a Linux image generated by the Freescale Yocto BSP. For reference I've been appending these video parameters:
to the mmcargs environmental variable.
However, this does not seem to work. I'm wondering if anyone has previously used this display module with the SabreSD board or the i.MX6 platform?

I don't remember if I ever tried touch with the iMX6 and that display. It's probably a driver you have to enable (look at the sabreSD schematics to see it's connected to an ADC).
