2012-02-20MIPS: Alchemy: Increase minimum timeout for 32kHz timer.Manuel Lauss
Since a clocksource change post 3.2-rc1, tasks on my DB1500 board hang after random amounts of time (from a few minutes to a few hours), regardless of load. Debugging showed that the compare-match register value is a few seconds lower than the current counter value. The minimum value of 8 was initialy determined by a trial-and-error approach. Currently it is sufficient for all Alchemys (without PCI apparently), independent of CPU clock; only the DB1500 and DB1550 boards experience these timer-related tasks hangs now. This patch increases the minimum timeout by 1 (to 9 counter ticks) which seems sufficient since the systems are still working perfectly fine after over 24 hours.

2011-12-08MIPS: Alchemy: db1200: Improve PB1200 detection.Manuel Lauss
The PB1200 has the CPLD located at an address which on the DB1200 is RAM; reading the Board-ID sometimes results in a PB1200 being detected instead (especially during reboots after long uptimes). On the other hand, the address of the DB1200's CPLD is hosting Flash chips on the PB1200. Test for the DB1200 first and additionally do a quick write-test to the hexleds register to make sure we're writing to the CPLD.

2011-12-07MIPS: irq: Remove IRQF_DISABLEDYong Zhang
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.
