* bsp/powerpc: Move libcpu timer to bspsSebastian Huber2018-03-221-4/+0
| | | | | | | | | Use only one timer driver variant based on the standard PowerPC time base. This patch is a part of the BSP source reorganization. Update #3285.
* bsps/powerpc: Remove bsp_timer_internal_clockSebastian Huber2018-03-221-2/+0
| | | | | | | | | | | | | The only consumer of this variable was the ppc403 clock driver used by the * haleakala, * virtex, and * virtex4 BSPs which set bsp_timer_internal_clock unconditionally to true. Update #3285.
* Remove make preinstallChris Johns2018-01-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* virtex5: Simplify bsp_specsJoel Sherrill2017-12-201-0/+2
| | | | Updates #3520.
* powerpc: Remove _BSP_Fatal_error()Sebastian Huber2017-11-221-12/+0
| | | | | | | BSPs can use the bsp_fatal_extension() to provide BSP-specific fatal error handling. There is no need for a _BSP_Fatal_error(). Close #3246.
* powerpc: Replace BSP_panic() with rtems_panic()Sebastian Huber2017-11-221-12/+0
| | | | | | | | Due to a new rtems_panic() implementation, it is possible to replace the PowerPC-specific BSP_panic() with rtems_panic(). Remove BSP_panic() implementations. Close #3245.
* Simplify and unify BSP_output_charSebastian Huber2017-09-121-1/+1
| | | | | | | | 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.

* powerpc: Change interrupt disable implemetationSebastian Huber2014-02-191-3/+1
| | | | | | | | | | | | Instead of SPRG0 (= special purpose register 272) use the new global symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask. The benefit is that it is now possible to disable interrupts without further run-time initialization in boot_card(). At least on Freescale e500 cores this leads also to a faster execution since the mfmsr and mfspr instruction require four cycles to complete. The instructions to load the mask value can execute while the mfmsr is in progress.
* score: Add CPU counter supportSebastian Huber2014-02-141-0/+4
| | | | | | | | | Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.
* bsps: Thread-local storage (TLS) for linkcmdsSebastian Huber2014-02-041-0/+17

* score: rtems_initialize_start_multitasking()Sebastian Huber2012-12-071-7/+1
| | | | | | | | | Do not return from rtems_initialize_start_multitasking() and call rtems_fatal() instead with a fatal source of RTEMS_FATAL_SOURCE_EXIT and a fatal code with the exit status. Remove all bsp_cleanup() functions. The boot_card() is now a no return function.
* Virtex5 BSP: Various updates and improvements.Ric Claus2012-12-013-94/+122
| | | | | This BSP now uses the MPC6xx clock driver instead of a modified PPC403 clock driver. Support for the MMU has been added, but is not enabled by default.
* bsps/powerpc: Exception initialization error is fatalSebastian Huber2012-11-151-5/+3

* score: Add RTEMS_FATAL_SOURCE_EXITSebastian Huber2012-11-151-2/+13
| | | | | | | Include <bsp/default-initial-extension.h> in all BSPs. Call rtems_fatal() with RTEMS_FATAL_SOURCE_EXIT as source and the exit() status code as fatal code in every bsp_cleanup(). Move previous bsp_cleanup() code into bsp_fatal_extension().
* bsps: Include <bsp/bootcard.h>Sebastian Huber2012-11-141-2/+2
| | | | | Use <bsp/bootcard.h> to get prototype for bsp_cleanup(). Fix bsp_cleanup() definition if necessary.
* Add Virtex4 and Virtex5 BSPsRic Claus2012-03-305-0/+1124
This commit covers at least PR2020, 2022, and 2023. This patch adds all of the code for both BSPs, modifications to libcpu/powerpc for the ppc440, and some updates to the BSPs from follow up review and testing. These BSPs should be good baselines for future development. The configurations used by Ric are custom and have a non-standard NIC. They also do not have a UART. Thus the current console driver just prints to a RAM buffer. The NIC and UART support are left for future work. When the UART support is added, moving the existing "to RAM" console driver to a shared location is likely desirable because boards with no debug UART port are commonly deployed. This would let printk() go to RAM.
