[RFC PATCH 3/5] powerpc and pseries updates for new OF dynamic code
Nathan Fontenot
nfont at austin.ibm.com
Thu Nov 5 09:18:35 EST 2009
Updates to powerpc generic and powerpc/pseries. This patch removes the
dynamic device tree updating code from prom.c and deletes the no longer
neccessary pSeries_reconfig.h file, all of the functionality is now in the
generic OF code.
The remaining changes deal with updating code for name changes with using
the OF code.
