- 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.
