Agreed but the situation at that point was the code was not at
all in convertible position. Looking at your below comment,
it's still not :)

We did discuss this Russell and requested your help here. I guess
you have already looked at OMAP code from generic suspend
hooks point of view and the SRAM execution, Errata's seems to
make you feel it's not going to work.
Is that what you mean here ?
