[PATCH] ppc64: PCI reset support routines
13-eeh-recovery-support-routines.patch
EEH Recovery support routines
This patch adds routines required to help drive the recovery of
EEH-frozen slots. The main function is to drive the PCI #RST
signal line high for a qurter of a second, and then allow for
a second & a half of settle time.
