2009-04-22m68knommu: Fixed GPIO pin initialization for CONFIG_M5271 FEC.Richard Retanubun
This processor only have one FEC and its MDIO pins are located at a different offset than the code used for the current CONFIG_M527x. Tesed on M5271EVB eval platform. Without this patch the FEC driver will report no PHY attached if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

2009-03-24m68knommu: fix 5407 ColdFire UART vector setupGreg Ungerer
There is a couple of problems with the UART vector setup for the 5307 ColdFire UART. The ICR register access should be 8bit, not 32bit. The address of the UIVR register is wrong, it needs to be offset into the MBAR register region. Fix these. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2009-01-27m68knommu: use one exist from execptionSebastian Siewior
Part of the code that did not make sense to me got removed by Greg. This is part two: The first compare is to check whether the interrupts are disabled or not. Depending on the result we exectute the RESTORE_ALL macro is not only restoring the stack but also returning to caller. The test for pending softirq has been removed because it is allready done in irq_exit(). Since system_call() is allso using the SAVE_ALL macro and returning via ret_from_exception label I see no reason why we could not do this here as well. This is also handy because if we return from the timer interrupt and we need to resched than we check for this :) Signed-off-by: Sebastian Siewior <bigeasy@linutronix.de> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2008-12-13cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell
Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function. Another single-patch change.

2008-07-23m68knommu: put ColdFire head code into .text.head sectionGreg Ungerer
Switch the ColdFire head start up code to be in the .text.head segment. And make sure that segment is at the start of the final linked text segment. Fixes the linker warnings about section use mis-matches: WARNING: vmlinux.o(.text+0xa8): Section mismatch in reference from the variable _clear_bss to the function .init.text:start_kernel() The function _clear_bss() references the function __init start_kernel(). This is often because _clear_bss lacks a __init annotation or the annotation of start_kernel is wrong. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2008-07-23m68knommu: MCF5307 PIT GENERIC_CLOCKEVENTS supportSebastian Siewior
The PIT code has been changed in order to suppport GENERIC_CLOCKEVENTS. The priority of the PIT clocksource has been decreased in favor of the DMA timer. pit_cycles_per_jiffy become a constant (PIT_CYCLES_PER_JIFFY) because it is known at compile time and does not change afterwards.
