Subject[PATCH RESEND 5/5] MIPS: Loongson64: Mark RS780 HPET as broken
Date
This driver is using some dangerous hack to set MMIO address for HPET,
which might break systems with other kinds of PCH.

Also, as Loongson-3 cpufreq driver never appeared in mainline,
this driver rarely got used.

So we temporarily mark it as broken until we find a better solution.

This option enables the hpet timer of AMD RS780/SBX00.

- If you want to enable the Loongson3 CPUFreq Driver, Please enable
- this option at first, otherwise, You will get wrong system time.
