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.

||
