* psim: Rework device tree so devices do not conflict with 256MB RAMJoel Sherrill2020-03-054-15/+12
| | | | updates #3849.
* bsp/mpc5643l_*: Exclude some testsSebastian Huber2020-02-272-0/+4
| | | | These tests do not fit into the available memory.
* bsps: Rework work area initializationSebastian Huber2020-02-045-45/+128
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.
* bsps: Add RTEMS_SYSINIT_BSP_EARLYSebastian Huber2020-02-045-38/+48
| | | | | | | Add new BSP system initialization step for work to be performed before the work areas are initialized. Update #3838.
* bsps: Add RamEnd to linker command filesSebastian Huber2020-02-047-0/+7
| | | | Update #3838.
* bsps/powerpc: Fix warningSebastian Huber2020-01-021-3/+1
| | | | Update #3834.

| | | | Close #3339.
* clock: Simplify driver initializationSebastian Huber2019-12-114-29/+4
| | | | | | Use a system initialization handler instead of a legacy IO driver. Update #3834.
* clock: Remove Clock_exit() from APISebastian Huber2019-12-114-24/+2
| | | | | | | This function is no longer supported by the standard clock driver implementation (clockimpl.h). Update #3436.
* bsp/mpc55xxevb: Remove obsolete linker cmd fileSebastian Huber2019-11-251-1/+0
| | | | Update #3818.
* bsp/gen83xx: Remove obsolete linker command fileSebastian Huber2019-11-251-19/+0
| | | | Update #3818.
* bsp/t32mppc: Rename linker command fileSebastian Huber2019-11-141-0/+0
| | | | | | | This BSP family uses only one linker command file. Use the standard name. Update #3818.
* bsp/motorola_powerpc: Fix linker command fileSebastian Huber2019-06-271-1/+2
| | | | | | | | Fix the __size symbol value to reflect the total size of the bootloader. This prevents a bootloader crash with application images above a certain threshold (e.g. fileio sample program). Update #3727.
* bsps/powerpc: Adjust ppcboot.ldsSebastian Huber2019-05-271-10/+14
| | | | | | | | | | | | | | | | The GNU ld had a couple of changes which resulted in a broken bootloader image generation. Recent linker versions tie assignments to their nearest output section statement. Place all absolute symbols which are used with @sectoff relocations into a special section. See also: "Binutils 2.28 on PowerPC: dangerous relocation: generic linker can't handle R_PPC_SECTOFF_HA" https://www.sourceware.org/ml/binutils/2019-05/msg00183.html Update #3727
* bsps: Always build generic interrupt supportSebastian Huber2019-05-168-0/+12
| | | | | | | This makes it possible to write tests for the generic interrupt controller support. Update #3269.
* bsps/powerpc: Fix constructors with prioritySebastian Huber2019-05-071-19/+8
| | | | Update #3339.
* bsps/powerpc: Fix C++ exception handlingSebastian Huber2019-05-071-2/+3

| | | | Update #3122.
* score: Rename _SMP_Get_processor_count()Sebastian Huber2019-04-111-1/+1
| | | | | | | Rename _SMP_Get_processor_count() in _SMP_Get_processor_maximum() to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
* score: Rename _SMP_Processor_countSebastian Huber2019-04-111-1/+1
| | | | | | | Rename _SMP_Processor_count in _SMP_Processor_maximum to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-091-1/+1
| | | | | | | | | | | Add rtems_scheduler_get_processor() as a replacement for rtems_get_current_processor(). The rtems_get_current_processor() is a bit orphaned. Adopt it by the Scheduler Manager. This is in line with the glibc sched_getcpu() function. Deprecate rtems_get_current_processor(). Update #3731.
* Set the small data section size to max. for beatnik BSPs.Goetz Pfeiffer2019-04-041-0/+2
| | | | | This applies changes similar to patch 294c6f46a6 to the beatnik BSP. This is a board support for the mvme5500 and mvme6100 CPU.
* Set the small data section size to max. for mvme5500 and mvme2100 BSPsChris Johns2019-03-302-0/+4
| | | | Closes #3728
* bsps/powerpc: Initialize stack earlierSebastian Huber2019-03-151-9/+9
| | | | | | The __eabi() call may use the stack. Update #3459.

| | | | | Move the .rtemsstack section from a read-only to a read-write area, see page table setup in __BSP_default_pgtbl_setup().
* bsps/powerpc: Fix PAGE_ALIGN() macrosSebastian Huber2019-03-043-3/+3
| | | | | Previous warning fixes which include <sys/param.h> broke this macro. The definition of PAGE_MASK changed.

* bsps/powerpc: Fix small data area sectionSebastian Huber2019-02-115-20/+26
| | | | | | | | | | Fix small data area in case no fixed size is desired. Rename bsp_section_set_sdata_sbss_size into bsp_section_small_data_area_size since this symbol reflects the overall small data area size (including space for libdl). Do not use bsp_section_sbss_size before definition in linker command file. Add new symbols to <bsp/linker-symbols.h>. Update #3687.
* libdl: Add powerpc large memory and small data support.Chris Johns2019-02-094-2/+25
| | | | | | | | | | | | | | | | | - Add support for architecure sections that can be handled by the architecture back end. - Add trampoline/fixup support for PowerPC. This means the PowerPC now supports large memory loading of applications. - Add a bit allocator to manage small block based regions of memory. - Add small data (sdata/sbss) support for the PowerPC. The support makes the linker allocated small data region of memory a global resource available to libdl loaded object files. Updates #3687 Updates #3685
* powerpc/psim: Increase the psim memory to 256MChris Johns2019-02-093-4/+9
