2009-09-16m68knommu: clean up ColdFire 528x interrupt setupGreg Ungerer
With the common intc-2 interrupt controller code in place the ColdFire 528x family startup code can be greatly simplified. Remove all the interrupt masking code, and the per-device interrupt config here. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2009-09-16m68knommu: general interrupt controller for ColdFire many 52xx partsGreg Ungerer
Create general interrupt controller code for the many ColdFire version 2 cores that use the two region INTC interrupt controller. This includes the 523x family, 5270, 5271, 5274, 5275, and the 528x families. This code does proper masking and unmasking of interrupts. With this in place some of the driver hacks in place to support ColdFire interrupts can finally go away. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-09-16m68knommu: remove per device interrupt mask setting for ColdFire 520xGreg Ungerer
With general interrupt controller code in place we don't need specific unmasking code for the internal ColdFire 520x UARTs or ethernet (FEC). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-09-16m68knommu: use general interrupt controller for ColdFire 520x familyGreg Ungerer
Create general interrupt controller code for the ColdFire 520x family, that does proper masking and unmasking of interrupts. With this in place some of the driver hacks in place to support ColdFire interrupts can finally go away. Within the ColdFire family there is a variety of different interrupt controllers in use. Some are used on multiple parts, some on only one. There is quite some differences in some varients, so much so that common code for all ColdFire parts would be impossible. This commit introduces code to support one of the newer interrupt controllers in the ColdFire 5208 and 5207 parts. It has very simple mask and unmask operations, so is one of the easiest to support.

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>
