All,
It was found that the ubuntu-desktop is a bit memory hungry on this i.MX53 QuickStart board. There is a large chunk of memory being reserved for the graphics/video drivers, and the memory size reserved has to consider the worst case. And we have to live with this before the unified memory allocator is available.
I don't yet have a /proc/meminfo after system is right up, I'll get some statistics a bit later. However, I do want to know if we have some memory footprint evaluation of the existing ubuntu-desktop (we are using unity-2d)? And what can we do to improve on that?

There's some old data I recorded on netbook-efl which is probably the closest data I know about:
https://wiki.linaro.org/Platform/DevPlatform/MemoryFootprintSampleData#netbo...
I've been focusing on kernel work this cycle, so I don't know if the memory footprint work has been moving forward.
Steve may know who's involved now.

Mmm... this doesn't look very bad. I'll do some testing more on this later.
