=== Highlights ===
* Completed the power measurement with and without memory regions patches,
but did not find any savings in power consumed.
* Did further testing at hardware level (with only u-boot executing, no linux)
and found a issue with memory controller settings. After fixing the issue,
there is about 60mA of savings when all the banks of the 4 DDR3 modules
connected to one memory controller are kept in precharge power-down
mode versus when read/write activity are active on them.
* Submitted third version of the clkdev patches.
=== Plans ===
* Re-run the tests with memory regions patches. Also find a test
equipment that can provide average power consumed when a
test case is executed.
