2005-01-20[PATCH] ppc32: System platform_device description, discovery and managementKumar Gala
On most embedded PPC systems we either have a core CPU and chipset (MPC10x, TSI10x, Marvell, etc.) or a system-on-chip device (4xx, 8xx, 82xx, 85xx, etc.). Some of these sub-archs have been using the On Chip Peripheral (OCP) driver model. The functionality that OCP provide has been replaced by the generic driver model and platform_device. Also, some of these device may exist across a number of architectures (PPC, MIPS, ARM) such that some information that is shared between the architecture and driver needs to exist outside of either. The ppc_sys changes add a standard way for PowerPC systems to describe the devices and systems that exist in the sub-arch. Additionally, we are able to discover which system we are and manage which devices are actually registered and any platform specific fixups that may be needed.

2004-11-25[PATCH] ppc32: Fix an IRQ issue with cpufreqBenjamin Herrenschmidt
The ppc32 PowerMac cpufreq code, when using the PMU to switch the frequency, would eventually lose interrupts. The solution is to raise the CPU priority at the controller level. It's also unnecessary to call the full PIC suspend/resume code in this case as the IO chip isn't reset, unlike the sleep code.

2004-11-24[PATCH] ppc32: Have the 8260 board-hook happen a bit laterTom Rini
Borut Lukic <borutlukic@email.si> brought to my attention that in platform_init() on 8260 the board hook was being called too early to allow for overrides (e.g. different memory sizings functions or rtc, or anything else). This moves the call to the end of platform_init() and I suspect fixes some unnoticed yet bugs in a number of 8260 platforms.

Here's a patch which backs out the fix Randy Vinson came up with, and makes i8259_init() and openpic_hookup_cascade() use setup_irq (tested on LoPEC). This also converts the rest of the request_irq callers that were expecting the old behavior (psurge SMP, chrp xmon, 85xx, some 82xx). This is more untested, but looks correct. I've left 8xx alone in this as it needs other changes before it would make sense.
