* Added generic Micro FrameBuffer interface for MicroWindows.
This interface allows MicroWindows to under RTEMS. A sample
driver has been developed for the pc386 BSP. See
pc386/fb_vga.c as a sample.
* Added Uniform Input Device interface for MicroWindows.
See PC386 bsp for sample drivers for mouse and keyboard (console).
* mw-bf: New directory.
* Makefile.am, configure.in, wrapup/Makefile.am: Account for mw-fb.
* mw-fb/Makefile.am: New file.
* mw-fb/mw_fb.c: New file.
* mw-fb/mw_fb.h: New file.
* mw-fb/mw_uid.c: New file.
* mw-fb/mw_uid.h: New file.
* taskstart.c: Removed 1st cut at rtems_task_start_main_style.
Only committed this so it could be easily revisited as we
discussing moving main() to user space from BSP space.
* cpu.c: Spacing issues.
* rtems/score/cpu.h: Removed warning by setting _level.
2000-08-29 Joel Sherrill <joel.sherrill@OARcorp.com>
* Makefile.am: Added S_O_FILES to list of objects.
* rtems/score/no_cpu.h: Modified so there are fewer and
more consistent variations on "no cpu" so it is easier
to sed the source as the starting point for a new port.
* inline/rtems/posix/timer.inl, include/rtems/posix/timer.h,
inline/rtems/posix/Makefile.am, src/ptimer1.c: Redid the
style of src/ptimer1.c. Continued effort to make the
POSIX Timer implementation match that of other managers.
Added data structures required to use SuperCore Object Handler.
the correct circumstances of DMA buffer size, serial
line interrupts, and ethernet interrupts the termios osend routine would
lock up waiting for the raw output buffer semaphore.
That BSP now has a stub clock driver so the tests can link even
if they won't execute. A handful of Makefiles had to be updated
and we had to account for printk.c being a shared file now.

of Canon CRF - Communication Dept. This port includes a
basic BSP that is sufficient to link hello world.
a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.

This update addresses the following:
+ the ISR enable/disable/flash macros now work with old gcc versions.
+ the UI CCR bits are now masked since other example code did so
+ _ISR_Dispatch disables interrupts during call setup
Together these removed the instabilities he was seeing.
routines and structures that require CPU model specific information
are now in libcpu. This primarily required moving erc32 specific
information from score/cpu files to libcpu/sparc and the erc32 BSP.
routines and structures that require CPU model specific information

score/cpu header files and the creation of multiple header files
and subdirectories in libcpu/i960.
that decouples exec/ for the sh, m68k and i960 from targopts.h.
NOTE: The change to system.h is a hack to enable cpuopts.h
for some targets, but keep using targopts.h for others - I know it
does *not* work for sparc, mips, i386 and ppc. This will have
to be addressed as work continues on multilibing.
that addresses aspects of the targopts.h multilib related
issues.
Changes:
* Move targopts.h to libbsp/include, because the current targopts.h
actually is a per-BSP-header and therefore can not stay below exec/.
* Introduce an autoheader generated header file
(exec/score/include/rtems/score/cpuopts.h), which shall take per-cpu
configuration options only.
* Move all autoconf-detectable/configure specified per-cpu
option-defines from targopts.h to cpuopts.h.
* Add Makefiles to the libbsp/shared directory hierarchy.
Notes:
* The new per-bsp targopts.h in libbsp includes the per-cpu
cpuopts.h. This way, the new targopts.h is kept backward compatible
to the old targopts.h and existing BSPs which (carelessly) include
targopts.h (i386, ppc) should be kept working when using the
multilib-disabled configuration scheme.
* cpuopts.h is not yet complete, because the per-BSP make-targopts
rules from custom/<BSP>.cfg files can not be applied to files below
exec/ when building multilibs.
* All files below exec/ should not include targopts.h anymore, but
should include cpuopts.h instead. However, eliminating inclusion of
targopts.h currently triggers further structural / header file inclusion
related issues, because several ports apply BSP or CPU_MODEL specific
defines from targopts.h below exec/
from score/cpu to libcpu because the determination of which to use is
based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on
multilib information.
where alarm() did not correctly account for the watchdog start_time
and stop_time fields being based on ticks not seconds. This resulted
in alarm() returning a bogus number of seconds remaining.
