MIPS: Alchemy: Increase minimum timeout for 32kHz timer.

2012-02-20T17:33:18Z

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.

MIPS: Alchemy: db1200: Improve PB1200 detection.

2011-12-08T10:42:16Z

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.

MIPS: Alchemy: merge Au1000 and Au1300-style IRQ controller code.

2011-12-08T10:42:16Z

With a generic plat_irq_dispatch (for Alchemy at least) code for both interrupt controller types can coexist in a single kernel image and be autodetected at runtime.

MTD: nand: make au1550nd.c a platform_driver

2011-12-08T10:42:10Z

Transform the au1550nd.c driver into a platform_driver and hook it up in the PB1550 board (gen_nand works fine on the DB1550, but since I don't have a PB1550 to test this driver stays for now).
