Currently different drivers requiring to access cpu device node are
parsing the device tree themselves. Since the ordering in the DT need
not match the logical cpu ordering, the parsing logic needs to consider
that. However, this has resulted in lots of code

This patch moves the generalized implementation of of_get_cpu_node from
PowerPC to DT core library, thereby adding support for retrieving cpu
node for a given logical cpu index on any architecture.
The CPU subsystem can now use this function to assign of_node in the

Hi,
This series needs to be prepended with the original series[1][2][3]
Except the first patch in the original series(which is merged into this
as last patch), there is no other change(apart from function signature)
I am posting only this part for feedback separately

This patch removes the declaration of the function 'of_get_cpu_node'
which is not defined for openrisc. This is in preparation to move
it's definition from PPC to DT common code.
Again it could be there as it was originally copied from powerpc.

Yes that's the idea, see the last paragraph in the commit log.
