[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.
