-Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
-
-The bgmac driver is using the bcma provides device ID and revision, as
-well as the SoC ID and package, to determine which features are
-necessary to enable, reset, etc in the driver. In anticipation of
-removing the bcma requirement for this driver, these must be changed to
-not reference that struct. In place of that, each "feature" has been
-given a flag, and the flags are enabled for their respective device and
-SoC.
