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. + +Signed-off-by: Gabor Juhos <juhosg@freemail.hu> +--- +--- a/arch/mips/ath79/prom.c ++++ b/arch/mips/ath79/prom.c +@@ -104,6 +104,7 @@ static int __init ath79_prom_init_myload + void __init prom_init(void) + { + const char *env; ++ char *c; + + if (ath79_prom_init_myloader()) + return; +@@ -137,6 +138,15 @@ void __init prom_init(void) + } + #endif + ++ /* ++ * RouterBOOT uses "Board" kernel parameter instead of "board" since ++ * version 3.41 (or so).
