* bsps: Move startup files to bspsSebastian Huber2018-04-204-193/+0
| | | | | | | | Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
* Remove make preinstallChris Johns2018-01-251-0/+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.

* bsp/csb336: Memory map update and jump to start at image start provided.Pavel Pisa2013-08-141-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CSB336 i.MX1/i.MXS memory map organization - SDRAM starts at address 0x08000000 but 2 MB are reserved for boot-block/loader (or other use) before RTEMS image origin/load address (that is kept from previous setup) - Caching of 30 MB of SDRAM used for RTEMS (start at 0x08200000) is changed to writeback mode which provides higher throughput. - The first 1 MB of RTEMS dedicated SDRAM is remapped to address 0 to provide area for ARM CPU exceptions table. - Internal registers and rest of the Flash (above 1 MB) are mapped one to one. Registers region is extended to 2 MB to cover eSRAM found on i.MX1 chip variant. - The first two megabytes of SDRAM unused by RTEMS are mapped with attributes to allow specific purposes. - the first MB (at address 0x08000000) is nocached to allow directly set some values read by booot-block after warm reset - the second MB (at address 0x08100000) is set for write-through caching. That allows to use memory for LCD frame-buffer without need to flush cache after each redraw. Jump to start provided at address 0x08200000 allows to load application image even as plain binary file and start it by jump to image start address. Signed-off-by: Pavel Pisa <ppisa@pikron.com>
* bsp/csb336: Fix MMU _ttbl_base location to not overlap with exception vectors.Pavel Pisa2013-08-091-3/+4
| | | | | | | | | | | | | The initial region (64 bytes) of SDRAM RTEMS image is remapped to provide overlay of the initial/ROM exceptions table. This area cannot be used for MMU mapping table. Different correctly aligned block has to be used for MMU table. Remapping of SDRAM (address 0x08200000) to address 0 is supported only on 1 MB block granularity and that is why SDRAM_VEC area has to be 1 MB aligned too but unused part of remapped region can be freely used for other purposes (as MMU tables).

* bsps: Replace NIRVANA regionSebastian Huber2012-06-121-1/+0
| | | | | Replace the "NIRVANA" region with the more verbose "UNEXPECTED_SECTIONS" region. Move the region definition into the "linkcmds.base" files.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-112-4/+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.
* General - Remove extraneous blank line in license messageJoel Sherrill2012-05-031-1/+0
| | | | | | | | | | | | | Many files had an extra blank line in the license text found in the file header. This patch removes that line. * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * * http://www.rtems.com/license/LICENSE. The script that did this also turned off execute permission when it was turned on incorrectly.

| | | | | | | | | | * Makefile.am, configure.ac, console/uart.c, startup/bspclean.c, startup/bspstart.c: 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/bspreset.c: New file.
* 2008-09-19 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill2008-09-191-0/+4

| | | | | | | * Makefile.am, configure.ac, startup/bspstart.c: Split out bsp_get_work_area() into its own file and user BSP Framework to perform more initialization. Let edb7312 and csb336 shared the implementation.
* 2008-08-21 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill2008-08-211-0/+0

| | | | | | | | | | | | | | | | | * csb336/startup/bspstart.c, csb337/startup/bspstart.c, edb7312/startup/bspstart.c, gba/startup/bspstart.c, gp32/startup/bspstart.c, rtl22xx/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.

| | | | | | | | | | | | * 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.

| | | | | | * 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.

| | | | | | | | | | * 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.

| | | | | | * startup/bspstart.c: Eliminate maximum_drivers configuration parameter since it was used to configure a no longer used feature. Device names are now part of the filesystem not in a table.
