Yes, but since the lower 64KB will not be available on non-GP device and
only A8 can access it, for now we make use of the higher 64KB which is referred
to as the OCMC RAM in the TRM. This will also enable SRAM usage by other drivers
like PRU and McASP.

You are right in saying that the dummy function is needed to avoid 34xx SRAM init.
We'll have some PM related code coming in soon and hopefully the SRAM code won't change
Without us noticing ;)
