Hm, I thought my powerdown issues on the Jetson TK1 were for lack of CONFIG_AS3277_RESET - sounds like it could be due to EFI instead? > Unfortunately we haven't implemented that one yet.

Can't you patch the reset_cpu() declaration (common.h/sysreset.h) instead of all its implementations? We might still need to patch individual implementations but I don't see why any reset_cpu() implementation should be in a different section than others.
