Subject: m68knommu: fix default starting date

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.

Subject: m68knommu: fix strace support for 68328/68360

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

Subject: m68knommu: add support for Coldfire 547x/548x interrupt controller

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.

Subject: m68knommu: stop using __do_IRQ

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).

Subject: m68knommu: add basic mmu-less m548x support

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.

Subject: m68knommu: mask of vector bits in exception word properly

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.

Subject: m68knommu: support the external GPIO based interrupts of the 5272

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.

Break up syscall_trace() into separate entry and exit routines that use
tracehook_report_syscall_entry() and tracehook_report_syscall_exit().
