* mcf52235/README, mcf52235/gdb-init, mcf52235/clock/clock.c,
mcf52235/console/console.c, mcf52235/include/bsp.h,
mcf52235/include/coverhd.h, mcf52235/start/start.S,
mcf52235/startup/bspclean.c, mcf52235/startup/bspstart.c,
mcf52235/startup/linkcmds, mcf52235/timer/timer.c: Cleaned up
white space and code formmated to adhere to RTEMS standards. Fixed
a bug in the nano seconds since last tick support. Fixed a bug
with the location of the start stack (no longer within
.bss). Removed double definition of IPSBAR and some type defs
etc.. Added timing test overhead results.
* mcf52235/include/mcf52235.h: Removed. Moved to the more generic
mcf5223x.h.
* mcf5223x/include/mcf5223x.h: New. Was mcf52235.h.
* Makefile.am, configure.ac, preinstall.am: Changed from mcf52235
to mcf5223x.
* sapi/include/confdefs.h: When you disabled newlib reentrancy, it
still reserved memory for the reentrancy structure. This is about 1K
per task. On psim, we now reserve only 1936 bytes and only 240 remain
after all allocations. Further analysis will be required to narrow
that down. In addition, the new constant CONFIGURE_CONFDEFS_DEBUG can
be defined and the structure named Configuration_Memory_Debug will be
instantiated. This structure contains many of the component values
that go into the memory reservation computation. This is helpful when
tracking down problems.
* sapi/include/confdefs.h: The math in the _Configure_Object_RAM macro
was always adding heap overhead even when the number of objects
configured was zero and we would not do an allocation. This resulted
in an over estimation of the amount of Workspace required (~2K on
minimum.exe on PowerPC).
* cpukit/sapi/include/confdefs.h: Add missing quote to string to
remove warning.
* cpukit/score/cpu/m68k/rtems/score/m68k.h: Add the default
priority level for large memory Coldfires.
* minimum/init.c: Exerise new ability for application to configure
minimum stack size. This test still runs the same with a 7.5K stack
on the powerpc but reserves 15K less Workspace on the PowerPC.
* user/bsp.t, user/conf.t, user/task.t: Add ability for application to
configure minimum stack size. Add RTEMS_CONFIGURED_MINIMUM_STACK_SIZE
constant so user can clearly indicate they want the configured as
opposed to the recommended minimum stack size.
* posix/include/rtems/posix/pthread.h, posix/src/pthread.c,
posix/src/pthreadcreate.c, rtems/include/rtems.h, rtems/src/attr.c,
sapi/include/confdefs.h, sapi/include/rtems/config.h,
score/inline/rtems/score/stack.inl, score/src/isr.c,
score/src/mpci.c, score/src/threadcreateidle.c,
score/src/threadinitialize.c, score/src/threadstackallocate.c: Add
ability for application to configure minimum stack size. Add
RTEMS_CONFIGURED_MINIMUM_STACK_SIZE constant so user can clearly
indicate they want the configured as opposed to the recommended
minimum stack size.
* cpu_asm.S: Add Coldfire FPU support.
* rtems/score/m68k.h: Change the Coldfire CPU defines to be based
on the instruction set. Add Tiny RTEMS support to the small memory
model RTEMS processors.
* rtems/score/cpu.h: Handle the new Tiny RTEMS support.

custom/mvme167.cfg, custom/ods68302.cfg, custom/sim68000.cfg,
custom/simcpu32.cfg, custom/uC5282.cfg: Change CCFLAGS to use the
-mcpu= option for Coldfires now supported in GCC 4.3.0.
2008-06-10 Matthew Riek <matthew.riek@ibiscomputer.com.au>
* custom/mcf52235.cfg: New.
* shared/m68kbspgetworkarea.c: Fix extern type to RamSize.
* shared/m68kpretaskinghook.c: Do not handle the RAM allocation if
the BSP is handling it.
* acinclude.m4: Add the mcf52235 BSP.
