[MIPS] Only build r4k clocksource for systems that work ok with it.

In particular as-is it's not suited for multicore and mutiprocessors systems where there is on guarantee that the counter are synchronized or running from the same clock at all.

[MIPS] Handle R4000/R4400 mfc0 from count register.

2007-11-26T17:26:14Z

The R4000 and R4400 have an errata where if the cp0 count register is read in the exact moment when it matches the compare register no interrupt will be generated. This bug may be triggered if the cp0 count register is being used as clocksource and the compare interrupt as clockevent. So a simple workaround is to avoid using the compare for both facilities on the affected CPUs. This is different from the workaround suggested in the old errata documents; at some opportunity probably the official version should be implemented and tested. Another thing to find out is which processor versions exactly are affected. I only have errata documents upto R4400 V3.0 available so for the moment the code treats all R4000 and R4400 as broken. This is potencially a problem for some machines that have no other decent clocksource available; this workaround will cause them to fall back to another clocksource, worst case the "jiffies" source.

[MIPS] time: Code cleanups

2007-11-02T16:13:46Z

* Do not include unnecessary headers. * Do not mention time.README. * Do not mention mips_timer_ack. * Make clocksource_mips static. It is now dedicated to c0_timer. * Initialize clocksource_mips.read statically. * Remove null_hpt_read. * Remove an argument of plat_timer_setup. It is just a placeholder.
