This fix is in response to test results reported by Jerry Needell
<jerry.needell@unh.edu> for the SPARC/ERC32 and tracked as PR80.
* include/bsp.h: TM27 was not running properly because the ERC32
and LEON cannot nest interrupts at the same level. The BSP test support
had to be modified to support using two different interrupt sources.
* start.S: Modificatins to preserve the current CWP and adjust the
WIM accordingly. This improves compatibility with the remote
debugger and the mkprom prom-builder.
* erc32sonic/erc32sonic.c: Minor modifications which enable
network interface to come up and work for some time before
getting an error in the SONIC driver. The error is a bit random,
sometimes MCLGET (m, M_WAIT) tries to access memory way outside the
available ram (and traps) while sometimes there is a panic due
to RBAE/RXEN.
* ChangeLog, .cvsignore, Makefile.am, bspclean.c, bspstart.c,
gnatcommon.c, start.S: New files. Largely moved from ERC32
BSP to be able to be shared with LEON and other SPARC BSPs.
* ChangeLog, .cvsignore, Makefile.am, bspclean.c, bspstart.c,
gnatcommon.c, start.S: New files. Largely moved from ERC32
BSP to be able to be shared with LEON and other SPARC BSPs.
* Makefile.am, configure.in, gnatsupp/Makefile.am,
gnatsupp/gnatsupp.c, include/Makefile.am, include/bsp.h,
start/Makefile.am, startup/Makefile.am, startup/setvec.c,
wrapup/Makefile.am:
* erc32sonic: New directory.
* erc32sonic/Makefile.am, erc32sonic/erc32sonic.c,
erc32sonic/.cvsignore: New files.
* include/erc32.h: New file.
* startup/boardinit.S: New file.
Big update of SPARC support for ERC32 and LEON.
Added support for ERC32 without floating point.
Added SONIC support as configured on Tharsys ERC32 board.
The bsp's share various code in the shared directory:
gnat-support, start-up code, etc.
To decrease the foot-print, I removed the 16 kbyte start-up
stack that was put in .bss and never reused once the system
was up. The stack is now put between the heap and the
workspace. To reclaim it, the user can do a rtems_region_extend
to merge the stack to the heap region once the system is up.
* startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
and libcsupport.h moved from libc to lib/include/rtems and
now must be referenced as <rtems/XXX.h>. Header file order
was cleaned up while doing this.
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.
that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)
Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain:
* Modifications, (minor) corrections, cleanups to most existing
Makefile.ams
* Adds automake support to all remaining BSPs which have not yet been
converted to automake.
* Makefile.am for all remaining wrapup/Makefile.ams
that contains:
* cleanups to configuration files
* A reworked gccnewlib.spec.in: I have reformated it for enhanced
readability and added more rtems-base packages. It now should be free of
any installation conflicts (If there still remain some, they should be
regarded as bugs).
* A fix to the bin2boot RTEMS_BSP issue (make RTEMS_BSP="pc386 pc486"
now works).
* removes libbsp/bare/wrapup
* Further cleanups
