2018-04-20bsps: Move startup files to bspsSebastian Huber1-113/+0
Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
2017-11-22powerpc: Remove _BSP_Fatal_error()Sebastian Huber1-6/+0
BSPs can use the bsp_fatal_extension() to provide BSP-specific fatal error handling. There is no need for a _BSP_Fatal_error(). Close #3246.
2017-11-22powerpc: Replace BSP_panic() with rtems_panic()Sebastian Huber1-6/+0
Due to a new rtems_panic() implementation, it is possible to replace the PowerPC-specific BSP_panic() with rtems_panic(). Remove BSP_panic() implementations. Close #3245.
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2014-02-19powerpc: Change interrupt disable implemetationSebastian Huber1-1/+0
Instead of SPRG0 (= special purpose register 272) use the new global symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask. The benefit is that it is now possible to disable interrupts without further run-time initialization in boot_card(). At least on Freescale e500 cores this leads also to a faster execution since the mfmsr and mfspr instruction require four cycles to complete. The instructions to load the mask value can execute while the mfmsr is in progress.
2014-02-14score: Add CPU counter supportSebastian Huber1-0/+2
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.
2013-07-05bsp/psim: Fix declarationRalf Kirchner1-2/+2
It declares a symbol defined in the linker command file.
2013-06-21bsps/powerpc: Delete bsp_exceptions_in_RAMSebastian Huber1-7/+3
Delete ppc_exc_vector_base. Add and use ppc_exc_initialize_with_vector_base().
2013-03-19bsp/psim: Use shared linkcmds.baseSebastian Huber1-11/+3
Several GCC tests faild due to the outdated previous linker command file.
2012-11-15bsps/powerpc: Exception initialization error is fatalSebastian Huber1-5/+1
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

* include/bsp.h, include/tm27.h, startup/bspstart.c: Use "__asm__" instead of "asm" for improved c99-compliance.
2009-11-152009-11-15 Till Straumann <strauman@slac.stanford.edu>Till Straumann1-3/+6
* startup/bspstart.c: use normal get_ppc_cpu_type() for determining PPC flavor. This causes the appropriate 'feature' bits to be set and should work as long as the PVR is set to 0xfffe0000 in the device tree. * startup/linkcmds: increased RAM_SIZE to 32M.

* start/start.S, startup/bspstart.c: Fix warnings.
2009-09-112009-09-11 Till Straumann <strauman@slac.stanford.edu>Till Straumann1-4/+4
* Makefile.am, preinstall.am, irq/no_pic.c (REMOVED), irq/irq.h, irq/irq_init.c: use openpic from 'shared' area instead of no_pic. * inlude/psim.h: use openpic from 'shared' area instead of no_pic. Added 'extern' declaration for (linker-script defined) RamBase and RamSize symbols. Let CPP macros expand to these symbols instead of static constants. Added register definitions for OpenPIC in the register area. Added register definitions for ethernet controller in the register area. * startup/linkcmds: Increased RamSize to 16M. Increased 'RAM' memory region to 32M (there is really no disadvantage in making this large). Added comment explaining the inter-relation between RamSize, the size of the memory region, the device-tree property "oea-memory-size" and the DBAT setting. * tools/psim-shared: Try to determine RamSize from executable and set 'oea-memory-size' accordingly. May be overridden if 'RAM_SIZE' envvar is set. Added openpic to device-tree. Added ethernet controller to device-tree (commented because a PSIM patch is currently required to use this device). * startup/bspstart: Increase DBAT0 mapping to size of 32M.

* Makefile.am, include/bsp.h, startup/bspstart.c, startup/linkcmds: Use PowerPC level shared bsp_get_work_area() implementation. * startup/bspgetworkarea.c: Removed.
2008-09-162008-09-16 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-20/+0
* Makefile.am, startup/bspstart.c: Add use of bsp_get_work_area() in its own file and rely on BSP Framework to perform more initialization. Remove unnecessary includes of rtems/libio.h and rtems/libcsupport.h. * startup/bspgetworkarea.c: New file.
2008-07-24Changed bsp_get_workarea() to bsp_get_work_area() andThomas Doerfler1-7/+10
added support for an optional separate heap area.

2008-05-152008-05-15 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-51/+13
* Makefile.am, configure.ac, startup/bspstart.c: Add capability for bootcard.c BSP Initialization Framework to ask the BSP where it has memory for the RTEMS Workspace and C Program Heap. These collectively are referred to as work area. If the BSP supports this, then it does not have to include code to split the available memory between the two areas. This reduces the amount of code in the BSP specific bspstart.c file. Additionally, the shared framework can initialize the C Library, call rtems_debug_enable(), and dirty the work area memory. Until most/all BSPs support this new capability, if the BSP supports this, it should call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When the transition is complete, this autoconf macro can be removed.
2008-05-122008-05-12 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-1/+0
* startup/bspstart.c: Refactored and renamed initialization routines to rtems_initialize_data_structures, rtems_initialize_before_drivers, rtems_initialize_device_drivers, and rtems_initialize_start_multitasking. This opened the sequence up so that bootcard() could provide a more robust and flexible framework which is easier to explain and understand. This also lays the groundwork for sharing the division of available memory between the RTEMS workspace and heap and the C library initialization across all BSPs.

* bsp_specs, include/bsp.h, startup/bspstart.c: Eliminate copies of the Configuration Table. Use the RTEMS provided accessor macros to obtain configuration fields.

* include/bsp.h, startup/bspstart.c: Move interrupt_stack_size field from CPU Table to Configuration Table. Eliminate CPU Table from all ports. Delete references to CPU Table in all forms.
2007-12-032007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-15/+0
* Makefile.am, startup/bspstart.c: Moved most of the remaining CPU Table fields to the Configuration Table. This included pretasking_hook, predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace, extra_mpci_receive_server_stack, stack_allocate_hook, and stack_free_hook. As a side-effect of this effort some multiprocessing code was made conditional and some style clean up occurred.

* startup/bspstart.c, Makefile.am: Initialize BATs and enable MMU to come closer to what other BSPs do. This allows us to use the shared irq_asm.S. No more individual assembly code :-)

1998-04-30Removed tripling of workspace API when POSIX API is enabled. confdefs.hJoel Sherrill1-1/+3
is now correct enough where this is not necessary. This was in to cover up the deficiencies in figuring out how much memory a GNAT/RTEMS application required. There is a good stab at this now.
1998-04-18psim now runs in both debug and non-debug mode.Joel Sherrill1-4/+3
1998-04-15Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1-28/+4
code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
1998-04-15Transitioned to shared bsp_libc_init() and cleaned up comments.Joel Sherrill1-52/+21
1998-04-15Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1-14/+0
to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.
