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.
