2000-08-01Patch rtems-rc-20000801-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-1/+1
that switches the sparc from targopts.h to cpuopts.h.
2000-07-27Port of RTEMS to the ARM processor family by Eric ValetteJoel Sherrill15-0/+1771
<valette@crf.canon.fr> and Emmanuel Raguet <raguet@crf.canon.fr> of Canon CRF - Communication Dept. This port includes a basic BSP that is sufficient to link hello world.
2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill22-3/+69
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.
2000-07-25Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-2/+0
that removes an unnecessary inclusion of @RTEMS_BSP@.cfg.

2000-07-17Update from Philip Quaife <rtemsdev@qs.co.nz> that was hand-merged.Joel Sherrill2-34/+75
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.
2000-07-13Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-2/+0
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 :)
2000-07-11Removed no cpu references.Joel Sherrill13-15/+15
2000-07-11Reworked score/cpu/sparc so it can be safely compiled multilib. AllJoel Sherrill12-660/+31
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.
2000-07-11Added Hitachi H8/300 to the list of CPUs that should be OK withJoel Sherrill1-0/+1
using cpuopts.h and not targopts.h.
2000-07-11Reworked score/cpu/i960 so it can be safely compiled multilib. AllJoel Sherrill6-851/+31
routines and structures that require CPU model specific information are now in libcpu. This required significant rework of the score/cpu header files and the creation of multiple header files and subdirectories in libcpu/i960.
2000-07-11Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill5-6/+13
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.
2000-07-10Patch rtems-rc-20000709-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill3-53/+16
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/
2000-07-10Patch rtems-rc-20000708-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill13-39/+0
that is another small step toward multilibs: Changes: * Eliminate RTEMS_CHECK_CUSTOM_BSP from all configure.ins below exec/ * Add RTEMS_CHECK_CUSTOM_BSP to the multilib-disabled branch in RTEMS_ENV_RTEMSCPU to preserve the old per-BSP building scheme functional. Notes: * --enable-multilibs is still non-functional * This patch should not have any influence on the old building scheme (--disable-multilib should silently fall back to the old building scheme). * running ./bootstrap is required after applying the patch
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill4-28/+10
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.
2000-07-07Moved __RTEMS_APPLICATION__ conditional to include the use of theJoel Sherrill1-1/+1
static inline routine _CORE_mutex_Seize_interrupt_trylock since static routines are not included when in an application.
2000-07-06Patch rtems-rc-20000705-3.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill14-15/+16
that is a somewhat experimental, multilib-related patch: Changes: * Use RTEMS_ENV_RTEMSCPU instead of RTEMS_ENV_RTEMSBSP in configure.ins below exec/. At the moment, RTEMS_ENV_RTEMSCPU is more or less an optical change to emphasize that these subdirectories shall not depend on RTEMS_BSP than a real behavioral change. * Add AC_DEFINE_* to several aclocal/*.m4 macros to prepare autoheader/autoconf generated targopts.h and similiar configuration headers. * c/src/configure.in: remove exec from cfg_subdirs if multilibs are enabled (c/src is build per bsp, exec shall be build per cpu in c/ or from the toplevel in future, when multilibs are enabled.) Notes: * This patch should not have any impact on the current building scheme. * --enable-multilib still does not work. * running bootstrap from the toplevel directory is required.

2000-06-29This is the initial addition of the port of RTEMS to theJoel Sherrill16-0/+2025
Hitachi H8 family. This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill <joel@OARcorp.com>. While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity.
2000-06-29Added RTEMS_CPU_HAS_16_BIT_ADDRESSES constant to disable codeJoel Sherrill1-0/+4
that breaks when the target has 16 bit address space. One of the H8 multilibs is a 16-bit address space CPU. When a real attempt is made to support this CPU model, the code that assumes an address is 32 bits will have to change. This constant is probably not flagging all impacted code.

2000-06-15Patch rtems-rc-20000615-1-cvs.diff from Ralf CorsepiusJoel Sherrill1-1/+1
<corsepiu@faw.uni-ulm.de> to fix a bad file reference.
2000-06-14Patch rtems-rc-20000614-sh.tar.gz from Ralf CorsepiusJoel Sherrill10-1824/+14
<corsepiu@faw.uni-ulm.de> that migrates the SH port to multilib'ing. This patch involved moving a number of files in the CVS repository, adding new files, and deleting files from their previous location. Ralf gave good instructions (not repeated here) and here are his notes: Note 1: In this version, I did not change the installation points of the headers which are moved inside of the source-tree. This is a temporary hack for not breaking compatibility with 4.5 based BSPs, but will probably not last once having real multilibs (We would have include file conflicts when several BSPs/CPU_MODELS share a common installation prefix). Note 2: I hope not to have broken too much, but I would not be astonished if something goes wrong. Note 3: There are more patches to come :)
2000-06-14Moved PowerPC cache management code to libcpu. Also compiledJoel Sherrill2-302/+0
mpc8xx libcpu support for the first time and remove includes of bsp.h, references to BSP_Configuration, and Cpu_table. All of these can be obtained directly from RTEMS now.
2000-06-14Thread iterator and libgjc support submitted too early.Joel Sherrill5-215/+9
2000-06-13Added crude i960ka support.Joel Sherrill3-6/+38
2000-06-13Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill2-306/+0
now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.
2000-06-12Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill1-61/+0
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart <Darlene.Stewart@nrc.ca> to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860.
