* bsps/imxrt: Simplify linkcmds and make it flexibleChristian Mauderer2021-07-026-64/+60
| | | | | | | | | Calling the memory FLASH and EXTRAM instead of FLEXSPI and SDRAM makes it simpler to support other types of external RAM. This patch also removes some of the calculations and improves names and documentation to avoid pitfalls. It removes a unnecessary memory definition. Update #4180
* bsps/imxrt: Allow different ARM PLL settingChristian Mauderer2021-07-022-0/+41
| | | | Update #4180
* m68k/uC5282: linkcmds KEEP and SORT sectionsGedare Bloom2021-07-011-15/+19
| | | | | Fixes a problem with bad epilog code in _fini and to keep sections necessary with the -ffunction/data-sections.
* bsp/leon3: Move bsp_interrupt_is_valid_vector()Sebastian Huber2021-07-012-16/+14
| | | | | This function is not performance critical. There is no need to implement it inline.
* bsp/leon3: Fix bsp_interrupt_is_valid_vector()Sebastian Huber2021-07-011-3/+7
| | | | | | | | | | The fix to address CID 1399742 (NO_EFFECT) in commit f8b6359415404540864f809cbcffb8c2200261e1 introduced a bug since LEON3_IrqCtrl_EIrq == -1 in case no extended interrupts are supported by the interrupt controller. Fix this by checking for LEON3_IrqCtrl_EIrq > 0. In addition, interrupt number 0 is reserved and should not be used.
* bsps: Fix GICv3 support for AArch32Sebastian Huber2021-06-301-3/+3
| | | | | | | | | | | The GICv3 support is shared between AArch32 and AArch64. For AArch32, the new AARCH64_IS_NONSECURE is never defined. Use ARM_MULTILIB_ARCH_V4 instead. This issue was introduced by 76c6caad52244ab9a14151620a80ff0f71035b6c. There is still a change in bsp_interrupt_vector_enable() for AArch32 compared to the version before 76c6caad52244ab9a14151620a80ff0f71035b6c.
* bsps/cadence-spi: Fix moduleid offsetKinsey Moore2021-06-291-0/+1
| | | | | Move the moduleid register to the correct offset according to Cadence IP documentation.
* bsps/zynq-uart: Make post baud change kick globalKinsey Moore2021-06-293-5/+14
| | | | | | | | The existing fix for the ZynqMP UART hardware bug only caught the vast majority of instances where it could occur. To fully fix the data corruption, this fix must be applied after every baud rate change. This makes the logic reset and kick apply in any locations where the baud rate could be changed.

* sparc: Simplify trap table initializationSebastian Huber2021-06-2410-116/+64
| | | | | | | | | | | | | | | Move _ISR_Handler() to a separate file since it is now only used if a handler is installed by _CPU_ISR_install_raw_handler(). Statically initialize the traps for external interrupts to use the new _SPARC_Interrupt_trap() which directly dispatches the interrupt handlers installed by rtems_interrupt_handler_install() via the BSP-provided _SPARC_Interrupt_dispatch(). Since the trap table is now fully statically initialized, there is no longer a dependency on the Cache Manager in the default configuration. Update #4458.
* bsps: bsp_interrupt_handler_dispatch_unchecked()Sebastian Huber2021-06-241-19/+40
| | | | | | Add bsp_interrupt_handler_dispatch_unchecked() as an alternative to bsp_interrupt_handler_dispatch(). It may be used if the caller can ensure that the vector number is valid.
* bsps/sparc: Use rtems_interrupt_handler_install()Sebastian Huber2021-06-2410-31/+98
| | | | | | | Avoid using set_vector() which depends on _ISR_Vector_table(). Prepare for a statically initialized trap table. Update #4458.
* sparc: More reliable bad trap handlingSebastian Huber2021-06-2410-578/+2
| | | | | | | | | | | | | Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap() for all unexpected traps. This enables a proper RTEMS fatal error handling right from the start. Do not rely on the stack and register settings which caused an unexpected trap. Use the ISR stack of the processor to do the fatal error handling. Save the full context which caused the trap. Fatal error handler may use it for error logging. Unify the _CPU_Exception_frame_print() implementations and move it to cpukit. Update #4459.
* bsps/sparc: Add a symbol for each trap table entrySebastian Huber2021-06-241-95/+264
| | | | | | | | This makes it easier to review start.o and set break points to trap table entries. This change was checked by inspecting the trap table in start.o with objdump. Update #4458.
* bsp/atsam: Fix BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-241-1/+1
| | | | | | Fix an off by one error. Update #3269.
* bsps/irq: Default BSP_INTERRUPT_VECTOR_COUNT == 0Sebastian Huber2021-06-241-2/+5
| | | | | | | Change the default value of BSP_INTERRUPT_VECTOR_COUNT so that no interrupt vectors are supported and all related directives return RTEMS_INVALID_ID. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-2455-65/+0
| | | | | | This define is no longer used. Update #3269.
* bsps/irq: Use BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-2415-21/+21
| | | | | | Use BSP_INTERRUPT_VECTOR_COUNT instead of BSP_INTERRUPT_VECTOR_MAX. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_NUMBERSebastian Huber2021-06-242-4/+2
| | | | | | Replace it with BSP_INTERRUPT_VECTOR_COUNT. Update #3269.
* bsps/irq: Add BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-2455-0/+67
| | | | | | | | | | | | | Assert BSP_INTERRUPT_VECTOR_MAX + 1 == BSP_INTERRUPT_VECTOR_COUNT. After building all BSPs with this patch, BSP_INTERRUPT_VECTOR_MAX can be removed and replaced by BSP_INTERRUPT_VECTOR_COUNT. The BSP_INTERRUPT_VECTOR_COUNT allows a default implementation which supports no interrupt vector at all. Using COUNT instead of MAX may avoid some interpretation issues, for example is the maximum value a valid vector number or not. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-2460-106/+15
| | | | | | | | | | Remove BSP_INTERRUPT_VECTOR_MIN and unconditionally let interrupt vector numbers start with zero. The BSP_INTERRUPT_VECTOR_MIN == 0 invariant was tested by the previous commit and building all BSPs. Update #3269.
* bsps/irq: Assert BSP_INTERRUPT_VECTOR_MIN == 0Sebastian Huber2021-06-241-0/+4
| | | | | | | After building all BSPs with this patch, this BSP-specific define can be removed to simplify the implementation. Update #3269.
* bsp/generic_or1k: Remove incomplete IRQ supportSebastian Huber2021-06-242-45/+1
| | | | Update #3269.
* bsp/genmcf548x: Change BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-241-1/+9
| | | | | | | | | This BSP uses a customized implementation of the interrupt extension API. It was the only BSP which defined BSP_INTERRUPT_VECTOR_MIN to a value other than zero. Define it to zero and use a custom bsp_interrupt_is_valid_vector() function instead. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_NO_HEAP_USAGESebastian Huber2021-06-243-40/+3
| | | | | | | Remove the support for BSP_INTERRUPT_NO_HEAP_USAGE. This was only used by one BSP and provides no real benefit. Update #3269.
* grlib: Register system console as /dev/consoleSebastian Huber2021-06-241-1/+5
| | | | Close #4461.
* bsps/powerpc, bsps/shared: Move remaining legacy networking header filesVijay Kumar Banerjee2021-06-238-2359/+0

* bsp/leon3: Fix compile errorSebastian Huber2021-06-231-1/+1
| | | | Fix compile error with RTEMS_DRVMGR_STARTUP = True.
* bsps/i386: Update calibration of TSC to be more accurateJan Sommer2021-06-211-33/+38
| | | | Closes #4455
* bsps/irq: Change license to BSD-2-ClauseSebastian Huber2021-06-1711-97/+242
| | | | | | | Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* grlib: Simplify apbuart_inbyte_nonblocking()Sebastian Huber2021-06-171-5/+5
|
* grlib: Fix apbuart_outbyte_polled() prototypeSebastian Huber2021-06-172-2/+2
| | | | Callers usually want to output a character.
* grlib: Add apbuart_outbyte_wait()Sebastian Huber2021-06-176-24/+24
|
* grlib: Remove NL -> CR in apbuart_outbyte_polled()Sebastian Huber2021-06-176-12/+4
| | | | This is already done in rtems_putc().
* bsps/leon3: Auto initialization for printk()Sebastian Huber2021-06-171-28/+14
| | | | | | Get rid of the hack to output into the idle stack during the early system initialization. This fixes also a couple of test program failures which fail due to missing output.
* grlib: Add ambapp_plb()Sebastian Huber2021-06-1719-63/+96
| | | | | Replace the global variable ambapp_plb with a function to allow an automatic on demand initialization.
* grlib: Customizable allocation in ambapp_scan()Sebastian Huber2021-06-172-26/+42
| | | | | Make the memory allocations in ambapp_scan() customizable via the new struct ambapp_context parameter which generalizes the memory copy handler.
* bsps/sparc: Simplify memory initializationSebastian Huber2021-06-102-34/+39
| | | | | | | | | | | | | Directly initialize the memory in the start sequence defined by start.S instead of using a system initialization handler. This avoids using the global variable rdb_start which used a memory location which was shared with _ERC32_MEC_Timer_Control_Mirror. This change makes it possible to use _Memory_Allocate() even before the system initialization is started. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* bsps/sparc: Simplify stack initializationSebastian Huber2021-06-101-28/+21
| | | | | | Initialize the stacks for all processors in one place. Do not rely on Per_CPU_Control::interrupt_stack_high and directly use the statically allocated interrupt stack area.
* bsps/sparc: Unify stack initializationSebastian Huber2021-06-101-8/+6
| | | | | Initialize the stacks in start.S in one place and identical to _CPU_Context_Initialize().
* bsps/sparc: Remove support to load data sectionSebastian Huber2021-06-101-32/+4
| | | | | | | | | | | | | | | | | | Remove the support to load the data section and rely on the boot loader. The code is an artifact from the old erc32 days, when we would boot and execute from ROM and the .data had to be copied over to RAM. With leon1/2/3, this is not used anymore as a boot loader is made from the RAM image using a custom tool (mkprom). In SMP configurations, this support was also broken since LEON3_Boot_Cpu (in the data section due to the -1 initialization value) was used quite early in the start sequence. If the data copy is really necessary, then an application can still add this step as a very early system initialization step, since boot_card() and the system initialization loop does not use initialized read-write data (only read-only and BSS data). However, the SMP startup would still not work in this case. A boot loader is a better place to load the sections.
