It depends on what you plan to do with the DDR state and if
you want to preserve it. I have never tired it, but it should be possible.
You need to look at the datasheet for the TPS65217C for the
power sequencing and power down modes available.

on the software side of this, where might I find the code that does this
now. for instance if I type shutdown at the prompt how does this actually
work? is the power sequencing all in the shutdown binary, or the kernel,
some of each, or where exactly? there is a shutdown command but what does

Can the beagle bone (black/white) be powered down to the point where
only the on chip RTC continues to run? If this is the case then the
need for an external RTC would seem nil. where can I find more info
about the power sequencing of the bones? The SRM shows the order in
which the rails are
