* build: Remove subdir-objects from BSP configure.acSebastian Huber2018-04-121-1/+1
| | | | | | | The subdir-objects do not work currently due to BSP sources in bsps and c and the existing build tree layout. Update #3387.
* bsps: Remove empty gnatinstallhandler.cSebastian Huber2018-04-121-1/+0
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Move bootcard.c to bspsSebastian Huber2018-04-121-1/+0
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Remove headers from librtemsbsp_a_SOURCESSebastian Huber2018-04-121-1/+0
| | | | | | | | This was used by the not supported "make dist". This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Avoid line continuation in Makefile.amSebastian Huber2018-04-121-1/+2
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Move legacy console driver to bspsSebastian Huber2018-04-122-5/+3
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* configure: Add subdir-objects to all automake flags.Chris Johns2018-04-111-1/+1
| | | | | | | | | | | This option silences warning with automake-1.16.1 allowing us to upgrade to that version. This change has been tested with automake-1.12.6 and automake-1.16.1. It seems version 1.16.1 configures slower than 1.12.6 for the same source and BSP. The newer versions is 6 second slower. Close #3387.
* build: Remove DISTCLEANFILESSebastian Huber2018-04-091-1/+0
| | | | | A "make distclean" is not supported. So, it makes no sense to have pure "make distclean" related stuff in the Makefile.am.
* bsps: Move generic IRQ support to bspsSebastian Huber2018-04-091-5/+1
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.

* bsps: Move config macros to RTEMS_BSP_CONFIGURESebastian Huber2018-04-041-7/+0
| | | | | | | | Provide HAS_NETWORKING and HAS_SMP Automake conditionals for all BSPs. This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Add shared-sources.amSebastian Huber2018-04-041-0/+1
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* build: Remove EXTRA_DISTSebastian Huber2018-04-041-2/+0
| | | | | A "make dist" is not supported. So, it makes no sense to have pure "make dist" related stuff in the Makefile.am.
* bsps: Rework cache manager implementationSebastian Huber2018-01-311-4/+1
| | | | | | | | | | | | | | | | | | The previous cache manager support used a single souce file (cache_manager.c) which included an implementation header (cache_.h). This required the use of specialized include paths to find the right header file. Change this to include a generic implementation header (cacheimpl.h) in specialized source files. Use the following directories and files: * bsps/shared/cache * bsps/@RTEMS_CPU@/shared/cache * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILY/start/cache.c Update #3285.
* bsps: Move network define to source filesSebastian Huber2018-01-311-20/+1
| | | | | Define __INSIDE_RTEMS_BSD_TCPIP_STACK__ in the network interface driver source files to avoid some build system magic.
* Remove make preinstallChris Johns2018-01-2517-1571/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* bsps: Add EXTRA_DIST to all BSP Makefile.amSebastian Huber2018-01-021-0/+1
| | | | | | | | | | This makes it possible to easily use EXTRA_DIST += foobar in fragments. Update #3254.

* libbsp/*/*/configure.ac: Remove references to bsp_specs in AC_CONFIG_SRCDIRJoel Sherrill2017-11-271-1/+1
| | | | Updates #3250.
* bsps: Provide <tm27.h> in each BSPSebastian Huber2017-11-273-2/+3
| | | | | | | | | Since the <tm27.h> is highly BSP-dependent and used only by the tm27 test program we must provide this header file for each BSP. Without the preinstall build target each header file must have a unique source header file. Update #3254.
* Remove coverhd.hSebastian Huber2017-11-242-6/+1
| | | | | | | This header file contained timing overhead values which are hard to maintain. Update #3254.
* bsps: Simplify RTEMS_BSP_CLEANUP_OPTIONSSebastian Huber2017-11-221-1/+1
| | | | | | | | | Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify the BSP configuration and documentation. Change defaults to: BSP_PRESS_KEY_FOR_RESET=0 BSP_RESET_BOARD_AT_EXIT=1 BSP_PRINT_EXCEPTION_CONTEXT=1
* getentropy: Add cpu counter based implementation.Christian Mauderer2017-11-171-0/+1

* bsps: Clock_driver_support_install_isr()Sebastian Huber2017-09-181-5/+2
| | | | | | | Remove old ISR parameter since is not used by the clock driver shell. Make an implementation optional. Update #3139.
* Simplify and unify BSP_output_charSebastian Huber2017-09-121-3/+0
| | | | | | | | The BSP_output_char should output a char and not mingle with high level processing, e.g. '\n' to '\r\n' translation. Move this translation to rtems_putc(). Remove it from all the BSP_output_char implementations. Close #3122.
* Include missing <string.h>Sebastian Huber2017-08-253-0/+5
| | | | Update #2133.
* bsps: Improve interrupt vector enable/disable APISebastian Huber2017-06-201-12/+4
| | | | | | Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable() to not return a status code. Add bsp_interrupt_assert() and use it to validate the vector number in the vector enable/disable implementations.

* arm/raspberrypi: framebuffer driver checks for initialization and tries ↵Pavel Pisa2016-07-311-1/+11
| | | | | | | | | | | | | | | runtime init if required. Code works but there is problem how to setup caching for the regions (arm_cp15_set_translation_table_entries arguments). If ARMV7_MMU_DATA_READ_WRITE_CACHED is used then CPU accesses are noncoherent with VideoCore and some part of image update are not visible until pushed from cache by other activities. If ARMV7_MMU_DATA_READ_WRITE is used then access is extremely slow. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* arm/raspberrypi: VideoCore access corrections in cache operation and more ↵Pavel Pisa2016-07-316-48/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | error checking. The first, mistake in buffer size computation for cache flush and invalidate has been corrected. GCC __attribute__( ( aligned( 64 ) ) ) should work and works for local variables. Code ensures right stack alignment. But attribute has to be moved to type declaration to ensure that structure size is affected by attribute. But even this seems to not work reliably for some reason. May it be, the stack area between frame start and end of local variable buffer accessed during context switch or some stack prefetch during resturn such way that some cache lines belonging to buffer are filled to cache. Extending buffer by one more cache line padding helps there. In the longer term perspective, buffer should be moved to some static area or cache aligned dynamic memory allocated. Concurrent calls to the VideoCore operations and access serialization should be added too but problem is that some calls are required during workspace and MMU setup so variant without need of mutex would be required as well. Framebuffer setup code and other VideoCore calls check more precisely for errors and do not proceed forward with incorrect data now. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>

* arm/raspberrypi: remove duplicate setup of IRQ handler in the main ARM ↵Pavel Pisa2016-07-232-21/+0
| | | | | | | | | | | | | | | | | | | | | | | exception table. Exception table setup is processed by common CPU architecture support. For ARM architecture, it can be found in the file rtems/c/src/lib/libbsp/arm/shared/start/start.S and ends by bsp_vector_table_copy_done label. The actual tabel content can be found at bsp_start_vector_table_begin For ARMv7-A and even other variant with hypervisor mode support, it is even not necessary to copy table to address 0 at all because CP15 register can be used to specify alternative table start address arm_cp15_set_vector_base_address(&)bsp_start_vector_table_begin; ARMv7-M have register to set exception table base as well.
