From b8b47bfbe4eb1ae0e6891e49c86a5f4fb00413be Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 11 Mar 2009 15:41:51 +0900 Subject: sh: pass along struct pci_channel These patches rework the pci code for the sh architecture. Currently each board implements some kind of ioport to address mapping. Some boards use generic_io_base others try passing addresses as io ports. This is the first set of patches that try to unify the pci code as much as possible to avoid duplicated code. This will in the end lead to fewer lines board specific code and more generic code. This patch makes sure a struct pci_channel pointer is passed along to various pci functions such as pci_read_reg(), pci_write_reg(), pci_fixup_pcic(), sh7751_pcic_init() and sh7780_pcic_init().
