cover meta-intel misc commits

From: Nitin A Kamble <[email protected]>

Here is a commit to add a kernel parameter to crownbay BSP. It is recommended in the EMGD 1.14 User Guide for video acceleration with the EMGD driver.

Darren,
Other EMGD based BSPs like FRI2 & sys940x should add the vmalloc=256MB kernel
parameter too. (not needed for noemgd BSPs)

Thanks,
Nitin

What does this actually do? It seems to work fine without it.

I'm familiar with the user-guide and have read through it. What I'm saying is that there should be a technical reason for adding a kernel command line and we should cite it in the commit. How does this improve the current state of things?

I have seen once the EMGD kernel driver throwing unable to allocate the memory errors while playing a video file. I guess the issue is scratched only in shortage of memory conditions.
