-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.
