Hi Kevin,
Just fyi, I tested pm-core(no patches of mine) against SDP3430(ES3.1)
and Beagle Rev C1(ES3.0) (that is the only board I could dig up): both
fail - I think basically <3630 is broken atm!.
Beagleboard:
with omap2plus_defconfig + MLO, u-boot.bin from
http://www.angstrom-distribution.org/demo/beagleboard/
filesystem is a minimal busybox that I had built and init=/bin/sh to
prevent any other apps running in the background - I use the same on
SDP3630 and 3430 platforms.
branch: pm-core (from your tree).
defconfig: omap2plus_defconfig - no changes other than disable RM680
board - currently causes a build failure.
test script - same one I had send to ML earlier today
