* bsps: Fix TLS support in linker command filesSebastian Huber2014-04-221-1/+3
| | | | | The TLS section symbols had wrong values in case of an empty TLS data section and a nonempty TLS BSS section.
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* powerpc: Change interrupt disable implemetationSebastian Huber2014-02-191-5/+1
| | | | | | | | | | | | 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.
* score: Add CPU counter supportSebastian Huber2014-02-141-0/+4
| | | | | | | | | 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.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+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.

| | | | | | * console/console.c, console/ns16550cfg.c, console/polled_io.c, include/bsp.h, include/tm27.h, startup/bspstart.c: Use "__asm__" instead of "asm" for improved c99-compliance.

* 2009-10-20 Till Straumann <strauman@slac.stanford.edu>Till Straumann2009-10-201-1/+3
| | | | | | | | | * startup/bspstart.c: let 'save_boot_params()' return a pointer to the commandline saved by the BSP which is NULL in this case. This pointer could be passed on to 'boot_card()' as it is done by other BSPs. This 'start/start.S' file however, passes a NULL pointer directly to boot_card() (w/o ever calling save_boot_params()).
* 2009-10-16 Ralf Corsépius <ralf.corsepius@rtems.org>Ralf Corsepius2009-10-161-3/+3

| | | | | | * Makefile.am, include/bsp.h, startup/bspstart.c: Use PowerPC level shared bsp_get_work_area() implementation. * startup/bspgetworkarea.c: Removed.

| | | | | | | * Makefile.am, configure.ac, console/rsPMCQ1.h, include/bsp.h, startup/bspstart.c: Create bsp_get_work_area() into its own file and use BSP Framework to perform more initialization. * startup/bspgetworkarea.c: New file.
* 2008-09-10 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill2008-09-101-1/+0
| | | | | | * startup/bspstart.c: Review of all bsp_cleanup() implementations. In this phase, all prototypes were removed from bsp.h and empty implementations were removed and made to use the shared stub.

| | | | | | | | | | | | | | * 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.
* 2008-05-12 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill2008-05-121-1/+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.

| | | | | | | * Makefile.am, 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.
* 2007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill2007-12-031-8/+0
| | | | | | | | | * 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.
