2018-04-20bsps: Move startup files to bspsSebastian Huber4-668/+0
Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
2018-03-12misc sh: Remove includes of rtems/score/types.hJoel Sherrill1-1/+0
2018-01-25Remove make preinstallChris Johns1-0/+9
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.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

* Makefile.am, configure.ac: Use standardized bsp_cleanup() which can optionally print a message, poll for user to press key, and call bsp_reset(). Using this eliminates the various bsp_cleanup() implementations which had their own implementation and variety of string constants. * startup/bspclean.c: Removed.
2008-09-162008-09-16 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-1/+2
* Makefile.am, startup/linkcmds: Use top level shared bsp_get_work_area() implementation.
2008-09-152008-09-15 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill2-109/+4
* Makefile.am, configure.ac, include/bsp.h, startup/linkcmds: Use shared bsp_get_work_area() in its own file and rely on BSP Framework to perform more initialization. After factoring this out, it turned out that all SuperH BSPs has the same bsp_start() implementation so this was made shared. * startup/bspstart.c: Removed.
2008-05-152008-05-15 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-4/+0
* startup/bspstart.c: Add capability for bootcard.c BSP Initialization Framework to ask the BSP where it has memory for the RTEMS Workspace and C Program Heap. These collectively are referred to as work area. If the BSP supports this, then it does not have to include code to split the available memory between the two areas. This reduces the amount of code in the BSP specific bspstart.c file. Additionally, the shared framework can initialize the C Library, call rtems_debug_enable(), and dirty the work area memory. Until most/all BSPs support this new capability, if the BSP supports this, it should call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When the transition is complete, this autoconf macro can be removed.
2008-05-122008-05-12 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-1/+0
* startup/bspstart.c: Refactored and renamed initialization routines to rtems_initialize_data_structures, rtems_initialize_before_drivers, rtems_initialize_device_drivers, and rtems_initialize_start_multitasking. This opened the sequence up so that bootcard() could provide a more robust and flexible framework which is easier to explain and understand. This also lays the groundwork for sharing the division of available memory between the RTEMS workspace and heap and the C library initialization across all BSPs.
2008-03-032008-03-03 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-1/+1
* startup/linkcmds: Add wildcard to gcc_except_table section so programs compiled with gcc 4.3.x can link.
2007-12-112007-12-11 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-11/+2
* include/bsp.h, startup/bspstart.c: Eliminate copies of the Configuration Table. Use the RTEMS provided accessor macros to obtain configuration fields.
2007-12-042007-12-04 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-12/+0
* include/bsp.h, startup/bspstart.c: Move interrupt_stack_size field from CPU Table to Configuration Table. Eliminate CPU Table from all ports. Delete references to CPU Table in all forms.
2007-12-032007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-3/+0
* Makefile.am, startup/bspstart.c: Moved most of the remaining CPU Table fields to the Configuration Table. This included pretasking_hook, predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace, extra_mpci_receive_server_stack, stack_allocate_hook, and stack_free_hook. As a side-effect of this effort some multiprocessing code was made conditional and some style clean up occurred.
2007-11-262007-11-26 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-1/+3
* startup/bspstart.c: Eliminate the clicks_per_microsecond field in the SuperH CPU Table and define another mechanism for drivers to obtain this information.
