Subject: atheros: ar2315-pci: update host bridge resources
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=94efeaa51f4e4f00160559c53ca6f601f2864560;p=librecmc%2Flibrecmc.git

atheros: ar2315-pci: update host bridge resources

It seems that the PCI controller does not support I/O ports, so remove
the ports range. Also correct the beginning of the memory range and its
size.
