From: Gabor Juhos Date: Sat, 2 Dec 2017 19:15:29 +0100 Subject: [PATCH] MIPS: ath79: fix board detection with newer RouterBOOT versions Recent RouterBOOT version (at least version 3.41 on RB911G-5HPacD) use "Board=" kernel parameter instead of "board=" to pass the board name to the kernel. Due to this change the board detection code is not working on the devices shipped with the new RouterBOOT version. Because the kernel is unable to identify these boards they become unusable despite that they are supported by the current code. Update the prom_init code to convert the 'Board' kernel parameter to 'board'. After this change, the board detection works also with the new RouterBOOT versions.

Subject: [PATCH 03/10] MIPS: BCM63XX: make fallback sprom optional

Some devices do not provide enough mac addresses to populate wifi in
addition to ethernet.

Use having pci enabled as a rough heuristic which boards should have it
enabled.
