2010-10-21microblaze: Clear return value in pt_regsMichal Simek
Signal code uses r3 value which saved in restore_sigcontext to rt_sigframe but it require to be zeroed. If is not zero rt_sigframe contains wrong values. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-10-21microblaze: Fix sys_rt_sigreturn_wrapperMichal Simek
Do not save return registers before rt_sigreturn is called. _user_exception(syscall handler) already setup return address that's why it is removed from rt_sigreturn_wrapper. Signed-off-by: Michal Simek <monstr@monstr.eu>

2010-10-21microblaze: Remove old user debugging gdb stubMichal Simek
Old gdb uses priviledged exception handler to handle gdb exception. New gdb uses brki r16, 0x18 that's why we can remove old gdb support. Signed-off-by: Michal Simek <monstr@monstr.eu>

2010-10-21m68knommu: support the external GPIO based interrupts of the 5272Greg Ungerer
The external GPIO interrupts of the ColdFire 5272 SoC are edge triggered, unlike the internal interrupt sources (which are level triggered). Add proper support for these interrupts. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68knommu: mask of vector bits in exception word properlyGreg Ungerer
The vector field of the processors exception frame actually contains both the vector exception number and fault status field bits. The exception processing code was not correctly masking out the fault status field bits before switching on the vector number. The default case was catching the bad check, but we are reporting the wrong kind of exception in some cases.

2010-10-21m68knommu: Fix MCFUART_TXFIFOSIZE for m548x.Philippe De Muyter
Serial lines on the MCF548x have really big fifos : 512 bytes. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68knommu: add basic mmu-less m548x supportPhilippe De Muyter
Add a very basic mmu-less support for coldfire m548x family. 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.

2010-10-21m68knommu: stop using __do_IRQGreg Ungerer
The use of __do_IRQ is deprecated, so lets stop using it. 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). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68knommu: rename PT_OFF_VECTOR to PT_OFF_FORMATVEC.Philippe De Muyter

2010-10-21m68knommu: add support for Coldfire 547x/548x interrupt controllerPhilippe De Muyter
The Coldfire MCF547x/MCF548x have the same interrupt controller as the MCF528x e.g., but only one, not two as in the MCF528x. Modify intc-2.c to support only one interrupt controller if MCFICM_INTC1 is not defined. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68k{nommu}: Remove unused DEFINE's from asm-offsets.cPhilippe De Muyter

2010-10-21m68knommu: Document supported chips in intc-2.c and intc-simr.c.Philippe De Muyter
The chips lists were in commit logs, but should also be in source files. This way it is easier to choose the right source file for a not yet supported Coldfire. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68knommu: fix strace support for 68328/68360Philippe De Muyter
strace enabled is marked using the `flags' field of the `thread_info' struct. 68360 version of entry.S did test a wrong bit in a wrong structure (task_struct). 68328 version of entry.S did test the right bit in the right structure, but wrongly, because the `flags' field is 32 bit wide, while the used assembler insn (btst) only accesses a 8 bit byte in memory. Fix both using code already used in the coldfire version of entry.S Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-10-21m68knommu: fix default starting datePhilippe De Muyter
Currently m68knommu boards without RTC chip start with an unexpected default date of 1999-11-30 (Actually the source asks for 2000-00-00) Make that 1970-01-01 instead, as expected. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
