I never trust the dts in the kernel wrt memory size, at least for TI
platforms as it's always 128MB and we've always gotten by with a
run-time fixup (or people not noticing their board had less memory than
it really does).  And, aside, they ought to adapt the PowerPC convention
of saying 0 for memory size so it's clear that the value is fixed up
elsewhere.

Yup.
