4 Subject: [PATCH 5/5] net: ethernet: bgmac: Add platform device support
5
6 The bcma portion of the driver has been split off into a bcma specific
7 driver. This has been mirrored for the platform driver. The last
8 references to the bcma core struct have been changed into a generic
9 function call. These function calls are wrappers to either the original
10 bcma code or new platform functions that access the same areas via MMIO.
11 This necessitated adding function pointers for both platform and bcma to
12 hide which backend is being used from the generic bgmac code.
