* score: Add CPU counter supportSebastian Huber2014-02-141-0/+11
| | | | | | | | | 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/arm: Fix Cortex-A9 MPCore nanoseconds handlerSebastian Huber2014-02-131-1/+1
|
* bsps/arm: Use Global Timer for Cortex-A9 MPCoreSebastian Huber2014-02-103-29/+74
| | | | | | Use the Global Timer for the Cortex-A9 MPCore clock driver instead of the Private Timer. This enables a consistent nanoseconds since last context switch value across all processors.
* bsps/arm: Include missing header fileSebastian Huber2014-02-101-3/+2

* bsps: Thread-local storage (TLS) for linkcmdsSebastian Huber2014-02-041-0/+8

* bsps: Fix barrier section definitionsSebastian Huber2014-01-301-3/+3
|
* bsps/arm: Use _ARMV4_Exception_interruptSebastian Huber2014-01-141-3/+3
| | | | | This allows read-only vector tables in ROM. It avoids also an unsolved problem with MMU/cache synchronization on SMP.
* bsps/arm: Use ALIGN_WITH_INPUTSebastian Huber2014-01-133-130/+90
| | | | | | | | | | | | | The ALIGN_WITH_INPUT helps to make this linker script more reliable. See also: https://sourceware.org/ml/binutils/2013-06/msg00246.html https://sourceware.org/binutils/docs-2.24/ld/Forced-Output-Alignment.html#Forced-Output-Alignment This reverts commit 4a9e52eefc510d7022ddc61c4ecde8db6b9a0217. This reverts commit 1ab4f76900d012b5a9dbce2851add060f11ce13a.

* arm/a9mpcore: Add support to get the clock via a weak linkage function.Chris Johns2013-12-192-2/+44
| | | | | | This allows an application to provide a localised clock freq with needing to go down the BSP opts path. This is important with the Zynq where the Xilinx tools generate the frequency.

* Revert "bsps/arm: Use ALIGN_WITH_INPUT"Chris Johns2013-12-193-84/+130
| | | | | | | This reverts commit 287bbb65afd24ffc6254ae5f328733213f184205. Conflicts: c/src/lib/libbsp/arm/shared/startup/linkcmds.base

|
* bsps/arm: Use ALIGN_WITH_INPUTSebastian Huber2013-12-163-119/+88
| | | | This requires at least Binutils 2.24.

|
* doxygen: refactored doxygen in libbsp/arm/lpc32xxDaniel Ramirez2013-11-296-9/+18
| | | | | | | | This patch refactors a lot of the existing doxygen within libbsp/arm/lpc32xx. Much of this refactoring was just renaming of existing groups to conform to a more consistent naming structure. With the addition of a doxygen header for tm27.h, all files within lpc32xx belong to doxygen group now. lpc32xx should be used a reference for adding doxygen to other bsps.

|
* bsps/arm: Move some MMU bit settingsSebastian Huber2013-10-272-2/+3
| | | | | | | The function arm_cp15_start_setup_translation_table_and_enable_mmu_and_cache() must only set the MMU and cache enable flags. Configuration flags must be set elsewhere.

* Shared MMU initialization for ARM BSPs and RaspberryPi MMU supportHesham AL-Matary2013-10-032-10/+39
| | | | | | | Add support for MMU initialization for RaspberryPi. Introduce new shared MMU configuration table that can be used by other BSPs that call the arm_cp15_start_setup_translation_table_and_enable_mmu_and_cache function. Demonstrate the use of the generic table with RaspberryPi.
* bsps/arm: Fix exception entriesRic Claus2013-09-161-2/+2

* bsps/arm: Use proper default priority for GICSebastian Huber2013-08-131-1/+1
| | | | | Some GIC implementations do not have the complete range of priorities. The upper bits are RAZ/WI in this case.
* smp: Add and use _CPU_SMP_Send_interrupt()Sebastian Huber2013-07-171-2/+2
| | | | Delete bsp_smp_interrupt_cpu().
* smp: Add and use _CPU_SMP_Get_current_processor()Sebastian Huber2013-07-171-5/+0
| | | | | | | | | | Add and use _SMP_Get_current_processor() and rtems_smp_get_current_processor(). Delete bsp_smp_interrupt_cpu(). Change type of current processor index from int to uint32_t to match _SMP_Processor_count type.

* bsps/arm: Rename functionSebastian Huber2013-06-241-2/+2
| | | | | | Rename arm_cp15_start_setup_translation_table_and_enable_mmu() in arm_cp15_start_setup_translation_table_and_enable_mmu_and_cache() to emphasize that the cache is also enabled after this operation.

* bsps/arm: Move .fast_text sectionSebastian Huber2013-05-271-9/+9
| | | | | | | Move the .fast_text section after the .vector section. The .fast_test section is normally not empty in case some functions should execute from an internal SRAM. This would be also the area for the .vector section. The vector table must be the first content of such an area.
* bsps: Update due to linker changesSebastian Huber2013-05-273-81/+112
| | | | | | | In case the VMA and LMA regions differ, the LMA start address is now no longer aligned with the alignment of the input sections: http://sourceware.org/bugzilla/show_bug.cgi?id=15222
