X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4b402c65a3a17257af45875159395278e4a2f0cd;p=openwrt%2Fstaging%2Fblogic.git [SSB]: Use ioreadX() and iowriteX() for PCI. On a PCI bus use ioreadX() and iowriteX(). We map the I/O space with pci_iomap(), so we must use the correct accessor functions, too. readX() and writeX() are not guaranteed to accept the cookie returned from pci_iomap() (though, it currently works on most architectures).
