      m68knommu: use common interrupt controller code for older ColdFire CPU's · 33a21263
      由 Greg Ungerer 提交于 
      The old ColdFire CPU's (5206, 5307, 5407, 5249 etc) use a simple
interrupt controller. Use common setup code for them. This addition
means that all ColdFire CPU's now have some specific type of interrupt
controller code.

      m68knommu: general interrupt controller for ColdFire 532x parts · 277c5e3e
      由 Greg Ungerer 提交于 
      The ColdFire 532x family of parts uses 2 of the same INTC interrupt
controlers used in the ColdFire 520x family. So modify the code to
support both parts. The extra code for the second INTC controler in
the case of the 520x is easily optimized away to nothing.

      m68knommu: general interrupt controller for ColdFire many 52xx parts · 2fba4f0b
      由 Greg Ungerer 提交于 
      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.

      m68knommu: use general interrupt controller for ColdFire 520x family · cd3dd406
      由 Greg Ungerer 提交于 
      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.

      m68knommu: use one exist from execption · c7bcd0df
      由 Sebastian Siewior 提交于 
      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 :)
