| * | m68knommu: remove the common interrupt controller structureGreg Ungerer2009-09-161-25/+0
| | | | | | | | | | | | | | | | | | | | | | | | Each different m68knommu CPU interrupt controller type has its own interrupt controller data structures now. Remove the old, and now not used, common irq structs and init code from here. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| | | | | | | | | | | | | | | | | | | | | | | | Define the interrupt controller structures along with the interrupt controller code for the 68360 CPU. This brings the interrupt setup and control into one place for this CPU family. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| * | m68knommu: use common interrupt controller code for older ColdFire CPU'sGreg Ungerer2009-09-164-28/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
| * | m68knommu: clean up ColdFire 532x interrupt setupGreg Ungerer2009-09-161-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | With the common intc-simr interrupt controller code in place the ColdFire 532x family startup code can be greatly simplified.

| * | m68knommu: general interrupt controller for ColdFire 532x partsGreg Ungerer2009-09-163-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| * | m68knommu: general interrupt controller for ColdFire many 52xx partsGreg Ungerer2009-09-163-4/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * | m68knommu: remove per device interrupt mask setting for ColdFire 520xGreg Ungerer2009-09-161-21/+0
| | | | | | | | | | | | | | | | | | | | | 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>
| * | m68knommu: use general interrupt controller for ColdFire 520x familyGreg Ungerer2009-09-163-1/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | linker script: unify usage of discard definitionTejun Heo2009-07-091-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Discarded sections in different archs share some commonality but have considerable differences. This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390.

Also, .discard is not thrown away while linking modules. Make every arch and module linking throw it away. This will be used to define dummy variables for percpu declarations and definitions.
