Subject: [PATCH] brcmfmac: use bar1 window size as provided by pci subsystem
|
||
|
|
|
||
|
|
The PCIE bar1 window size is specified by chip. Currently the
|
||
|
|
ioremap of bar1 was using a define which always matched the size
|
||
|
|
of bar1, but newer chips can have a different bar1 sizes. With
|
||
|
|
this patch the ioremap will be called with the by chip provided
|
||
|
|
window size.
