Indeed weak semantics are not really needed - even now we have what u r
suggesting
- the missing part was existing conditional definition which will simply go away
if I implement the fdt parsing in that singly defined function. Thx for the tip
:-)
In that case this requires no change to driver and I can fixup the platform -
perhaps ur Ack on next version will be nice.
Also what do u think of the early IER optimization ?
