From df9ee29270c11dba7d0fe0b83ce47a4d8e8d2101 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 7 Oct 2010 14:08:55 +0100 Subject: Fix IRQ flag handling naming Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

Generally the interrupts on the supported processors here are level triggered, so this is strait forward to switch over to using the standard handle_level_irq flow handler. (Although some ColdFire parts support edge triggered GPIO line interrupts we have no support for them yet).

This is perhaps also valid for m547x family. The port comprises the serial, tick timer and reboot support. The gpio part compiles but is empty. This gives a functional albeit limited linux for the m548x coldfire family. This has been tested on a Freescale M548xEVB Lite board with a M5484 processor and the default dbug monitor.
