This has been mirrored for the platform driver. The last -references to the bcma core struct have been changed into a generic -function call. These function calls are wrappers to either the original -bcma code or new platform functions that access the same areas via MMIO. -This necessitated adding function pointers for both platform and bcma to -hide which backend is being used from the generic bgmac code. - -Signed-off-by: Jon Mason <jon.mason@broadcom.com> -Acked-by: Arnd Bergmann <arnd@arndb.de> -Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> -Tested-by: Florian Fainelli <f.fainelli@gmail.com> -Signed-off-by: David S.
