* bsps/arm: Use shared empty bsp_start_hook_0()Sebastian Huber2024-01-151-0/+42
| | | | Update #4982.
* bsps/arm: BSP_START_VECTOR_ADDRESS_TABLE_ALIGNMENTSebastian Huber2023-12-061-0/+4
| | | | | Add the BSP option BSP_START_VECTOR_ADDRESS_TABLE_ALIGNMENT to optionally define an alignment of the vector address table begin.
* bsps/arm: Use interrupt entry for IPISebastian Huber2023-05-261-6/+10
| | | | Avoid a dynamic memory allocation for the inter-processor interrupt.
* Update company nameSebastian Huber2023-05-207-7/+7
| | | | | The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
* bsps/arm: Fix wordingSebastian Huber2023-03-171-1/+1
|
* bsps/arm: Mark functions in start.SSebastian Huber2022-09-221-0/+2
| | | | | | | Add the function type to _start() and bsp_start_hook_0_done() so that the linker can generate ARM/Thumb interworking code. Update #4202.
* bsps/arm: Add comment about banked FIQ registersSebastian Huber2022-09-221-0/+1
|
* bsps: Fix .data.rel.ro placementSebastian Huber2022-08-121-1/+1
| | | | | | | The .data.rel.ro* linker input section pattern accidentally matches with writeable data those symbol name starts with "ro". Close #4701.
* bsps: Sort .noinit* sectionsSebastian Huber2022-07-151-1/+1
| | | | | | | | Sort the .noinit* input sections by name first, then by alignment if two sections have the same name. This allows the placement of begin/end symbols to initialize some areas with a special value. Update #4678.
* bsps/arm/shared: Change license to BSD-2Joel Sherrill2022-07-083-9/+66
| | | | Updates #3053.
* bsp/arm: allocate .rtemsstack on REGION_STACK instead of on REGION_WORKKarel Gardas2022-05-231-1/+1
| | | | | | | | REGION_WORK may be backed by external RAM which may not be initialized in a time we need stack to work well. E.g. code loaded in flash, stack allocated on in-cpu SRAM and data (REGION_WORK) on external SDRAM. Sponsored-By: Precidata
* bsps/arm: Fix bsp_start_memcpy() for ARMv7-ARSebastian Huber2022-03-141-0/+4
| | | | Synchronize data and instruction streams.
* bsps/arm/: Scripted embedded brains header file clean upJoel Sherrill2022-03-107-42/+0
| | | | Updates #4625.
* bsps/arm: More robust SMP startSebastian Huber2021-08-121-2/+14
| | | | | Do not continue execution on processors which are not configured to prevent the use of arbitrary memory for the initialization stack.
* bsps/arm: Fix SMP startSebastian Huber2021-07-091-0/+6
| | | | | | | | Skip the data cache initialization if we are a secondary processor. The bug was introduced by e164df5e33608576443b4cd5923a9046358ee773 and did not show up in tests using Qemu since the data cache behaviour is not emulated.
* bsps/arm: Add start up support for ARMv6 RPi ModelsPranav Dangi2021-07-071-1/+7
|
* bsps/irq: Use BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-241-1/+1
| | | | | | Use BSP_INTERRUPT_VECTOR_COUNT instead of BSP_INTERRUPT_VECTOR_MAX. Update #3269.
* bsps: Support RTEMS_NOINIT in linkcmdsSebastian Huber2021-05-021-0/+7
| | | | Update #3866.
* bsps/arm: Set MSP in ARMv7-M start codeSebastian Huber2021-04-211-0/+8
| | | | | | Set the Main Stack Pointer (MSP) to the ISR stack area end just in case we run using the Process Stack Pointer (PSP). This helps if applications are started by a boot loader.
* bsps: Add missing DWARF 5 sectionsSebastian Huber2021-01-261-3/+5
| | | | Sort alphabetically.
* bsps: Support DWARF 5 sectionsSebastian Huber2021-01-251-8/+13
| | | | GCC 11 uses DWARF 5 by default.
* bsps/arm: Invalidate TLB in start.SSebastian Huber2020-12-231-0/+9
| | | | Update #4202.
* bsps/arm: Clear SCTLR[M, I, A, C] in start.SSebastian Huber2020-12-231-2/+35
| | | | | | | Initialize the data and unified cache levels. Invalidate the instruction cache levels. Update #4202.
* bsps/arm: Remove optional start hook argumentsSebastian Huber2020-12-231-37/+26
| | | | | | | The start hook arguments are not used by a BSP. Removing them avoids the need for a stack during the very early system initialization. Update #4202.
* bsps/arm: Invalidate branch predictors earlierSebastian Huber2020-12-231-0/+11
| | | | | | | Make sure the branch predictors are invalidated before the first branch is executed. Update #4202.
* bsps/arm: Set VBAR in start.SSebastian Huber2020-12-231-1/+27
| | | | | | | | | | Set the VBAR to the vector table in the start section before bsp_start_hook_0() is called to earlier handle exceptions in RTEMS. Set the VBAR to the normal vector table in start.S for the main processor. Secondary processors set it in bsp_start_hook_0(). Update #4202.
* bsps: Remove ARM GIC SGI target filterSebastian Huber2020-12-101-1/+0
| | | | | | | Remove the target filter for software-generated interrupts since this feature is not supported by the affinity routing in GICv3. Update #4202.
* bsps: Fix GICv3 arm_gic_trigger_sgi()Sebastian Huber2020-12-101-1/+1
| | | | | | | | Use the targets parameter to determine the targets of the SGI. Change targets parameter type to 32-bit to ease the parameter passing. GICv3 supports up to 16 targets. Update #4202.
* bsps/arm: Sort fast text/data sectionsSebastian Huber2020-10-211-2/+2
|
* bsps/arm: Add support for MPU region alignmentSebastian Huber2020-10-211-0/+21
| | | | Update #3910.
* bsps/arm: Use _Assert()Sebastian Huber2020-08-201-3/+2
|
* arm: ARMv7-M statically initialized vector tableSebastian Huber2020-04-031-5/+5
| | | | | | | Statically initialize the ARMv7-M vector table to allow a placement in ROM with read-only MPU settings. Change licence to BSD-2-Clause in some files.
* score: Statically allocate idle/MPCI stacksSebastian Huber2020-02-121-3/+7
| | | | | | | Place idle and MPCI stacks into extra linker sections. This can be optionally used by applications to control the placement of the stacks. Update #3835.
* bsps: Add RamEnd to linker command filesSebastian Huber2020-02-041-0/+1
| | | | Update #3838.
* bsps/arm: Export bsp_start_hook_0_doneSebastian Huber2019-12-191-5/+8
| | | | Close #3789.
* bsps/arm: Add zImage boot headerJeff Kubascik2019-12-051-0/+11
| | | | | Xen currently only supports the zImage loader for 32 bit guests on ARM targets.
* bsps/arm: Move HYP to SVC change to start.SSebastian Huber2019-07-262-78/+40
| | | | | | | | | This fixes the corruption of r3 by the call to bsp_start_arm_drop_hyp_mode(). Moving the code makes it easier to review changes in start.S. Close #3773.
* bsps/arm: Move register init to start.SSebastian Huber2019-07-262-109/+55
| | | | | | This makes it easier to review changes in start.S. Update #3773.
* bsps/arm: Remove register init for ARMv7-MSebastian Huber2019-07-261-12/+1
| | | | | | There are no known ARMv7-M chips with a dual lockstep mode. Update #3773.
* Remove superfluous <rtems/system.h> includesSebastian Huber2019-03-142-2/+0
|
* Remove explicit file names from @fileSebastian Huber2019-02-281-1/+1
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* bsps/arm: Move device tree copySebastian Huber2019-02-181-23/+24
| | | | | | Move device tree copy operation after the mode initialization so that bsp_fdt_copy() uses the initialization stack and not the stack provided up by the boot loader.
* bsps/arm: Remove unused bsp_stack_irq_sizeSebastian Huber2019-01-211-3/+0
| | | | Update #3459.
* bsps/arm: Avoid short range branch in start.SSebastian Huber2018-11-211-14/+13
|
* bsps/arm: Use local labels in start.SSebastian Huber2018-11-211-44/+40
|
* bsps/arm: Simplify start.SSebastian Huber2018-11-211-12/+0
| | | | The boot_card() function does not return.
* score: Rename interrupt stack symbolsSebastian Huber2018-11-081-4/+4
| | | | | | | | | | | | | Rename * _Configuration_Interrupt_stack_area_begin in _ISR_Stack_area_begin, * _Configuration_Interrupt_stack_area_end in _ISR_Stack_area_end, and * _Configuration_Interrupt_stack_size in _ISR_Stack_size. Move definitions to <rtems/score/isr.h>. The new names are considerable shorter and in the right namespace. Update #3459.
* bsps/arm: Recognize .tm_clone_table input sectionSebastian Huber2018-10-151-0/+3
|
* bsps/arm: Fix ctor/dtor invocation orderSebastian Huber2018-10-091-31/+4
| | | | Remove obsolete .ctor and .dtor output sections.
* score: _SMP_Inter_processor_interrupt_handler()Sebastian Huber2018-07-251-1/+1
| | | | | Pass current processor control via parameter since it may be already available at the caller side.
