* bsp/x86_64: Minimal bootable BSPAmaan Cheval2018-07-116-0/+97
| | | | | | | | | | | | | | | | Current state: - Basic context initialization and switching code. - Stubbed console (empty functions). - Mostly functional linker script (may need tweaks if we ever want to move away from the large code model (see: CPU_CFLAGS). - Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for UEFI-awareness. In short, the current state with this commit lets us boot, go through the system initialization functions, and then call user application's Init task too. Updates #2898.

* bsp/riscv_generic: New linker command fileSebastian Huber2018-06-271-0/+1
| | | | | | | This linker command file is based on the "riscv64-rtems5-ld --verbose" output. Update #3433.
* Rework initialization and interrupt stack supportSebastian Huber2018-06-274-22/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Statically initialize the interrupt stack area (_Configuration_Interrupt_stack_area_begin, _Configuration_Interrupt_stack_area_end, and _Configuration_Interrupt_stack_size) via <rtems/confdefs.h>. Place the interrupt stack area in a special section ".rtemsstack.interrupt". Let BSPs define the optimal placement of this section in their linker command files (e.g. in a fast on-chip memory). This change makes makes the CPU_HAS_SOFTWARE_INTERRUPT_STACK and CPU_HAS_HARDWARE_INTERRUPT_STACK CPU port defines superfluous, since the low level initialization code has all information available via global symbols. This change makes the CPU_ALLOCATE_INTERRUPT_STACK CPU port define superfluous, since the interrupt stacks are allocated by confdefs.h for all architectures. There is no need for BSP-specific linker command file magic (except the section placement), see previous ARM linker command file as a bad example. Remove _CPU_Install_interrupt_stack(). Initialize the hardware interrupt stack in _CPU_Initialize() if necessary (e.g. m68k_install_interrupt_stack()). The optional _CPU_Interrupt_stack_setup() is still useful to customize the registration of the interrupt stack area in the per-CPU information. The initialization stack can reuse the interrupt stack, since * interrupts are disabled during the sequential system initialization, and * the boot_card() function does not return. This stack resuse saves memory. Changes per architecture: arm: * Mostly replace the linker symbol based configuration of stacks with the standard <rtems/confdefs.h> configuration via CONFIGURE_INTERRUPT_STACK_SIZE. The size of the FIQ, ABT and UND mode stack is still defined via linker symbols. These modes are rarely used in applications and the default values provided by the BSP should be sufficient in most cases. * Remove the bsp_processor_count linker symbol hack used for the SMP support. This is possible since the interrupt stack area is now allocated by the linker and not allocated from the heap. This makes some configure.ac stuff obsolete. Remove the now superfluous BSP variants altcycv_devkit_smp and realview_pbx_a9_qemu_smp. bfin: * Remove unused magic linker command file allocation of initialization stack. Maybe a previous linker command file copy and paste problem? In the start.S the initialization stack is set to a hard coded value. lm32, m32c, mips, nios2, riscv, sh, v850: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. m68k: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. powerpc: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. * Used dedicated memory region (REGION_RTEMSSTACK) for the interrupt stack on BSPs using the shared linkcmds.base (replacement for REGION_RWEXTRA). sparc: * Remove the hard coded initialization stack. Use the interrupt stack for the initialization stack on the boot processor. This saves 16KiB of RAM. Update #3459.
* arm: Simplify CPU counter supportSebastian Huber2018-06-1519-19/+0
| | | | | | | | | | Use the standard ARMv7-M systick module for the ARMv7-M CPU counter instead of DWT counter since the DWT counter is affected by power saving states. Use an inline function for _CPU_Counter_difference() for all ARM BSPs. Update #3456.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-1512-0/+12
| | | | | | | | | | Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456.
* tools: Remove install-if-change programSebastian Huber2018-06-152-20/+7
| | | | | | | | | | | | | | | | | | | | | | | | The last installed tool in RTEMS repository is the install-if-change script. It is not used to build/install BSPs. This script does the same as the standard "install" program with an additional feature to install variants via the -V command line option. This script is used by the standard Makefile support: c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change The INSTALL_CHANGE is used by: c/src/make/host.cfg.in:ifndef INSTALL_CHANGE c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change c/src/make/host.cfg.in:INSTALL_VARIANT=$(INSTALL_CHANGE) -V "$(LIB_VARIANT)" Remove the support for variant installation and instead use the standard "install" program. This breaks application Makefiles using the standard Makefile support of RTEMS. Close #3455.

* make: Remove CFLAGS_DEBUG_OPTIMIZE_VSebastian Huber2018-06-151-4/+0
| | | | Do not document CFLAGS_DEBUG_OPTIMIZE_V, since this flag is not used.
* tools: Remove packhexSebastian Huber2018-06-151-3/+0
| | | | | | | | | | | | All tools should be removed from the RTEMS source repository at some point in time. Tools with a BSD-style license will be moved to the RTEMS tools repository. Unfortunately, this tool has no license information. Remove all uses of this tool from the code base. Users of HEX files should consider to use ELF instead. Close #3379.
* tools: Remove rtems-bin2cSebastian Huber2018-06-141-1/+1
| | | | | | This tool is now included in the RTEMS tools repository. Close #3380.
* tools: Remove shgenSebastian Huber2018-06-114-27/+4
| | | | | | | | | | | | All tools should be removed from the RTEMS source repository at some point in time. Tools with a BSD-style license will be moved to the RTEMS tools repository. Unfortunately, the shgen tool is GPL licensed. Remove all uses of this tool from the code base. Replace generated files with stub functions. If users of this BSP still exist, they can reimplement the functionality using a BSD-style license. Close #3443.
