Subject: sh: fix pci io access for r2d boards
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=123100cf4fff3e8ffa375df2c74c7f2cb29ab17a;p=deliverable%2Flinux.git

sh: fix pci io access for r2d boards

Use generic_io_base to point out the pci io window, and make sure the
highest port address used is SH7751_PCI_IO_SIZE - 1.

This patch fixes pci io port access for the r2d boards - CONFIG_8139TOO_PIO
now works as expected. So does the alsa driver for CMI8738.
