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 does the following:
Changes:
Remove $(SED) and $(CP) from make/custom/*.cfg
Motivation:
* autoconf and automake presuppose sed and cp to be present.
* make/host.cfg.in already contains SED = sed hard-coded into it for
a long time.
* Elimination of make-variables
* Eliminate make/*.cfg files or at least reduce their complexity :)
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.
that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
- Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and
cpuopts.h.
- Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE
(aclocal/rtems-test-no-pause.m4).
- Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins
and tmtests/configure.in. These are the only subdirectories which
currently apply RTEMS_TEST_NO_PAUSE.
- Add autoconf-DEFS support to all test subpackages' configure.ins
below tests/. I.e. AC_DEFINES now get explicitly propagated as
preprocessor defines into Makefiles, cf. AM_CPPFLAGS in
tests/*/*.am, instead of using a global config-files.
- Remove NDEBUG from custom/*.cfg.
* AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in
exec/configure.in, only.
- All other sources now should relay on the values from cpuopts.h
and should not define them themselves.
- Several related changes to many configure.ins
* Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to
quoting bugs in autoconf).
Notes:
* This patch is rather immature and only tested for a small subset
of BSPs (requires the tests to be enabled and therefore takes an
tremendous amount of disc space and time.)
* The patches to *cfg were generated by a script. Expect file
formating changes :)
that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_DEBUG a global per-cpu configuration option
* Remove RTEMS_DEBUG from targopts.h
* Add a global --enable-rtems-debug option disabled by default.
* Add RTEMS_DEBUG to cpuopts.h
* Remove all references to RTEMS_DEBUG from custom/*.cfg
Notes:
* RTEMS_DEBUG is set in c/src/exec/configure.in only
(RTEMS_CHECK_RTEMS_DEBUG) and should be defined in cpuopts.h only.
BSPs should not redefine it, but use the value being provided by
cpuopts.h.
=> With multilibs, users have to choose: Either enable RTEMS_DEBUG
for all BSPs and CPU_MODELs of a cpu or not.
* Only few BSPs had RTEMS_DEBUG enabled, therefore I set the default
to disabled.
* This patch influences the per-BSP building scheme. Existing BSPs
which set RTEMS_DEBUG in their make-target-options rule might have
problems at runtime.
