2010-02-24x86, apbt: Moorestown APB system timer driverJacob Pan
Moorestown platform does not have PIT or HPET platform timers. Instead it has a bank of eight APB timers. The number of available timers to the os is exposed via SFI mtmr tables. All APB timer interrupts are routed via ioapic rtes and delivered as MSI. Currently, we use timer 0 and 1 for per cpu clockevent devices, timer 2 for clocksource.

2010-02-23x86/PCI: Moorestown PCI supportJesse Barnes
The Moorestown platform only has a few devices that actually support PCI config cycles. The rest of the devices use an in-RAM MCFG space for the purposes of device enumeration and initialization. There are a few uglies in the fake support, like BAR sizes that aren't a power of two, sizing detection, and writes to the real devices, but other than that it's pretty straightforward. Another way to think of this is not really as PCI at all, but just a table in RAM describing which devices are present, their capabilities and their offsets in MMIO space. This could have been done with a special new firmware table on this platform, but given that we do have some real PCI devices too, simply describing things in an MCFG type space was pretty simple.

Different boards benefit differently from the available seven C-states for cpu idle. In most cases, only few, properly spaced (in terms of consumption and latency) C-states are required to make the power management optimal.

The CPUidle C state latencies and thresholds are dependent on various board specific details.

If the board files do not use this function to pass the params default values are used which might cause higher consumption dur to wrong state selection by the governor. This patch only updates the 3430sdp board files to use omap3_pm_init_cpuidle().
