MIPS: BCM47XX: Fix detected clock on Asus WL520GC and WL520GU (8eae19cc) · Commits · 戴 / test

The Asus WL520GC and WL520GU are based on the BCM5354 and clocked at 200MHz, but they do not have a clkfreq nvram variable set to the correct value. This adds a workaround for these devices. Signed-off-by:
