At the moment, bcm63xx creates one patch for each board to add to board_bcm963xx.c. While this is not really helpful to get an overview in the first place, it is particularly painful if you want to change something for an early file and have to refresh all the later patches accordingly. Since it does not look like these board patches are upstreamed either, this commit consolidates all board additions into one patch per "board". By this, both adding and editing boards should become much simpler, and we drop about 1300 lines of "code" from patches as well. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
