Hi
We have only 256M RAM on our board. When I start QML Application I get mxsfb 2220000.lcdif: Unable to allocate framebuffer memory

Preemptible hierarchical RCU implementation.
RCU restricting CPUs from NR_CPUS=4 to nr_cpu_ids=1
I increase the CMA memory to 160M (on EVK) and than it works. But on our board I can configure only 96M otherwise I get kernel panic.
Is the GPU Memory on a fix address or why does it not work with less then 160M CMA memory?
