Updates #3937.
2021-01-28bsps: Replace bsp_specs with an empty fileSebastian Huber1-9/+0

2018-04-20bsps: Move startup files to bspsSebastian Huber1-0/+0
Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
2018-01-25Remove make preinstallChris Johns1-0/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

Simplify bsp_specs These BSPs all use shared/startup/linkcmds.base and thus needed to be modified at the same time. Variations in the arguments were reflected into the BSP specific portions of the linkcmds. Updates #3520.

1999-04-06Patch from Andrew Bray <andy@chaos.org.uk>:Joel Sherrill1-0/+3
In your various bsp_specs files, even when ecrti.o is defined as a startfile, ecrtn.o is not defined as an endfile. Instead it seems to be in the library list - untidy.

Finally I am through: I have found the last bugs that made RTEMS- 4.0-beta3 start on my ppc403 board from ROM. So now the '403 support is up to date again. Roughly I have added the following features: - support for the on-chip interrupt controller (in a separate module) - interrupt support for the console device - termios support for the console device ============================================== Since the BSP behaivour changed in some details (console no longer is polling, other memory layout etc) I have created a new BSP "helas403" rather than changing the "papyrus" BSP. The old "polled" console driver still sticks around in "console.c.polled" To get the BSP up and running, I had to create the new BSP files (derived from papyrus). Besides that, the following source areas have been changed: - c/src/lib/libcpu/powerpc/ppc403: changes to console driver, small changes to clock driver, new "ictrl" interrupt controller driver - c/src/exec/score/cpu/powerpc/ppc.h: some small changes (added ppc403 characteristics like a exception vector prefix register, some special register definitions). I am quite sure, they are compatible with the existing sources, although I did not check - c/src/exec/score/cpu/powerpc/cpu.c: There is one severe limitation in the exception entries: Due to the current code arrangement, the "branch absolute" to the ISR handler may only jump to the first 128MByte or the last 128MByte of the 4GByte address range. When the ppc403 is running out of ROM, the ROM functions are located in the last 128MByte (0xFFF00000 and up). These addresses were not handled correctly (sign reduced) in "install_raw_handler". The change I added should work on existing ppc BSPs aswell... - c/src/lib/libc/termios.c: During my tests, I added one change you sent me, so this patch will already be incorporated in the current source tree. There are some smaller changes, see the attached diff file. ========================================= Concerning the GNU toolchain: I tried several tool chains. Finally I almost succeeded with egcs-1.0.3a with patch egcs-1.0.3-rtems-diff-19980527 I had to add the following lines to the egcs files. Without them configure complaint that the cross compiler could not generate executable output. - additional lines needed in egcs distribution in file gcc/config/rs6000/rtems.h: +++ lines start #undef STARTFILE_DEFAULT_SPEC #define STARTFILE_DEFAULT_SPEC "ecrti.o%s" #undef ENDFILE_DEFAULT_SPEC #define ENDFILE_DEFAULT_SPEC "ecrtn.o%s" ++++ lines end As far as I have seen in the Changelog of egcs, you have recently sent two patches affecting the powerpc support, but they were added in the wrong order.... :-( egcs-19980628 with patch egcs-19980628-rtems-diff-19980707 does not work! I used binutils 2.9.1 with patch binutils-2.9.1-rtems-diff-19980515 (binutils 2.8.1 does not work, internal error in gas) and newlib-1.8.0 with patch newlib-1.8.0-rtems-diff-19980707 Finally I had to poke a line in the "bit" script, since, on my LINUX machine, the GNU make is only available as "make", not as "gmake"... For all the tools and newlib I selected configuration "powerpc- rtems". -------------------------------------------- IMD Ingenieurbuero fuer Microcomputertechnik Thomas Doerfler Herbststrasse 8 D-82178 Puchheim Germany email: td@imd.m.isar.de

1997-12-20Moved -qnolinkcmds option so arguments passed on the command line areJoel Sherrill1-2/+2
interpreted at the right point per Eric Norum's discovery: The problem with the my previous `fix' for adding linker commands was with the ordering of the options to the linker. For example, to make a larger heap size, the application Makefile would CFLAGS_LD = -Wl,--defsym -Wl,HeapSize=0x40000 The command passed to the linker would be : m68k-rtems-ld .... -T xxx/linkcmds .... --defsym HeapSize=0x40000 ..... This doesn't work because the script in linkcmds inserts a default value for HeapSize if HeapSize is not defined by the time the linker looks at the linkcmds script. The solution seems to be to move the -T linkcmds%s in the bsp_specs file out of the link specfication and into the lib specification -- a little unorthodox, perhaps, but it seems to work!
