2018-04-20bsps: Move startup files to bspsSebastian Huber1-129/+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 Huber1-14/+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 Huber1-15/+1
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.
2014-10-07libchip/serial: Add alternative NS16550 driverSebastian Huber1-16/+18
Use the Termios device API.
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/+3
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.

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.
2012-04-02bsp/gen83xx: Fix console driver configurationSebastian Huber1-1/+1
2012-04-02bsps: More accurate PowerPC clock driverSebastian Huber1-3/+6
The clock driver used previously the bsp_clicks_per_usec value. For a 33333333Hz time base frequency this leads to a relative error of one per cent for example due to integer truncation.

* 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.

* Makefile.am, 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, 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.
