Hello,
I have wrote a test for CMA, it use a board specific driver in association with a script in userland. This test allow us to test buffer allocation/release on snowball.
The test is now running (locally) on LAVA.
I have put more documentation, patches and LAVA test description here : https://wiki.linaro.org/OfficeofCTO/MemoryManagement/Validation/CMATest
The blueprint for this stuff is: https://blueprints.launchpad.net/linaro-mm-sig/+spec/engr-umm-cma-debug
Next steps are: - run this test on LAVA farm boards. - write test drivers for other boards.
Regards, Benjamin

From a quick glance, other than the board file specific part, the
driver appears to be generic (not board or SoC specific). And even the registering of the platform device could be done in a more generic way, within the driver (ie. under drivers/, not under arch/) via an arch_initcall.
