[PATCH V2] MIPS: BCM47XX: fix position of cpu_wait disabling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hauke Mehrtens <hauke@xxxxxxxxxx>

The disabling of cpu_wait was done too early, before the detection was
done. This moves the code to a position where it actually works.
