Just leaving the CPU at 200MHz (instead of cranking it up to 400MHz in
board_init) saves 30mA, turning off the LDOs another 40mA. Almost there,
without even trying hard :-)
(The the 5s-20s segment corresponds to the measurements below.)
CPU at 200MHz:
We still seem to lose a few mA when we bring up the PMU (small step
near 6.5s). Our base consumption when just out of reset seems to be
Now, on to strangling the Glamo ...
