* gen5200, gen83xx, gen83x, mpc55xxevb, psim, qoriq, t32mppc, tqm8xx, virtex: ↵Joel Sherrill2017-12-202-5/+3
| | | | | | | | | | Simplify bsp_specs These BSPs all use shared/startup/linkcmds.base and thus needed to be modified at the same time. Variations in the arguments were reflected into the BSP specific portions of the linkcmds. Updates #3520.
* virtex/bsp_specs: Reorder and improve consistencyJoel Sherrill2017-11-291-2/+1
| | | | Updates #3520.
* REVERT */*/bsp_specs: Increase similarity to ease futureJoel Sherrill2017-11-271-1/+2
| | | | | | Patch was not intended to be pushed yet. Updates #3520.
* */*/bsp_specs: Increase similarity to ease future analysisJoel Sherrill2017-11-271-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Done: arm bfin epiphany i386 lm32 m32c mips moxie nios2 or1k powerpc riscv sh sparc sparc64 v850 To do: m68k Differences noted: + endfile was sometimes before startfile + endfile sometimes was hard-coded and did not have -qrtems version + Should -e XXX (e.g. entry point) be in linkcmds? + Should -u XXX (e.g. undefined symbols) be in linkcmds? + Typos: Odd spacing, "old_endfiles" typo, and *(old_endfiles) (not %) + nios2: Referenced crtnn.o not crtn.o (error) Need to revisit: + m32c, moxie, sparc64 includes !nostdlib which is not used elsewhere + sh has -EL/-EB mapping. Why needed? + sparc64 didn't include crti.o/crtn.o but it is part of toolset + v850 uses something like this for link and end_file: "%{qrtems: %(old_link)}" This means that these are unnecessary. Try this on all. + mips uses old_link all the time also. + arm/tms750 adds -EB. + powerpc: Why do we have rtems_crt* and not use something from GCC? Updates #3520.
* libbsp/*/*/configure.ac: Remove references to bsp_specs in AC_CONFIG_SRCDIRJoel Sherrill2017-11-271-1/+1
| | | | Updates #3250.
* bsps: Provide <tm27.h> in each BSPSebastian Huber2017-11-273-2/+3
| | | | | | | | | Since the <tm27.h> is highly BSP-dependent and used only by the tm27 test program we must provide this header file for each BSP. Without the preinstall build target each header file must have a unique source header file. Update #3254.
* Remove coverhd.hSebastian Huber2017-11-243-142/+0
| | | | | | | This header file contained timing overhead values which are hard to maintain. Update #3254.
* bsps: Simplify RTEMS_BSP_CLEANUP_OPTIONSSebastian Huber2017-11-221-1/+1
| | | | | | | | | Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify the BSP configuration and documentation. Change defaults to: BSP_PRESS_KEY_FOR_RESET=0 BSP_RESET_BOARD_AT_EXIT=1 BSP_PRINT_EXCEPTION_CONTEXT=1
* powerpc: Remove _BSP_Fatal_error()Sebastian Huber2017-11-221-12/+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.
* getentropy: Add cpu counter based implementation.Christian Mauderer2017-11-171-0/+1
| | | | Update #3239.
* Simplify and unify BSP_output_charSebastian Huber2017-09-121-3/+0
| | | | | | | | The BSP_output_char should output a char and not mingle with high level processing, e.g. '\n' to '\r\n' translation. Move this translation to rtems_putc(). Remove it from all the BSP_output_char implementations. Close #3122.
* bsps: Improve interrupt vector enable/disable APISebastian Huber2017-06-201-22/+10
| | | | | | Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable() to not return a status code. Add bsp_interrupt_assert() and use it to validate the vector number in the vector enable/disable implementations.
* bsp: Fixes due to header file changesSebastian Huber2017-06-132-16/+18
| | | | Update #2833.
* powerpc/virtex/include/bsp.h: Do not include <rtems/iosupp.h>Joel Sherrill2016-03-301-1/+0

* powerpc/virtex: Remove include of <rtems/console.h> from <bsp.h> and fix ↵Joel Sherrill2016-03-291-2/+0
| | | | warnings
* powerpc/virtex/include/bsp.h: Do not include <rtems/clockdrv.h>Joel Sherrill2016-03-271-1/+0

* Use linker set for libio initializationSebastian Huber2016-02-031-2/+2
| | | | Update #2408.

* bsps: Delete superfluous bsp_pretasking_hook()Sebastian Huber2015-12-101-1/+1
| | | | | | Use the bsp_predriver_hook() instead. Update #2408.
* Most bsp.h: Switch to LIBBSP_@CPU@_@BSP_FAMILY@_H for guardJoel Sherrill2015-07-161-2/+2

* bsps: Move extern "C" to not cover includesSebastian Huber2014-10-231-6/+6
| | | | Some includes may use C++ and this conflicts if surrounded extern "C".
* powerpc/virtex: Fix unused variable warningsJoel Sherrill2014-10-161-1/+1

* Regenerate all preinstall.am files.Chris Johns2014-08-291-3/+3
| | | | | With this patch the preinstall.am files are in a set order and not dependent on now perl implements a hash.
* Regenerate all preinstall.am files.Joel Sherrill2014-08-281-7/+7
| | | | | Apparently, at some point automake output changed and these were not updated.
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-219-10/+10

* bsps/powerpc: Use System V small-data areaSebastian Huber2014-02-241-1/+1
| | | | | | The 32-bit ABIs for thread-local storage (TLS) and EABI read-only small-data area have a conflicting register (r2) usage. Use the System V small-data instead (here r2 is system reserved).
* powerpc: Change interrupt disable implemetationSebastian Huber2014-02-191-1/+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.
* 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.
* libbsp powerpc: Add Doxygen file header to coverhd.hCynthia Rempel2014-01-141-1/+7

* Use $(EXEEXT) [defaults to "exe"] to generate binariesNick Withers2013-08-091-1/+1
|
* bsp/virtex: Use #if instead of #ifdefSebastian Huber2013-07-101-9/+9
| | | | | This allows VIRTEX_CONSOLE_USE_INTERRUPTS=0 on the configure command line to disable the interrupt mode.
* bsp/virtex: Add VIRTEX_CONSOLE_USE_INTERRUPTSSebastian Huber2013-07-092-37/+107
| | | | Add interrupt support for console driver.
* bsp/virtex: Use ppc_count_leading_zeros()Sebastian Huber2013-07-091-11/+10
| | | | Use ppc_count_leading_zeros() to optimize interrupt processing.
* bsp/virtex: Fix interrupt handlingSebastian Huber2013-07-091-9/+5
| | | | | | Some modules like the XPS UART Lite use event triggered interrupts. If we acknowledge the interrupts after the interrupt service we may loose these events.
* bsp/virtex: Use shared clock driverSebastian Huber2013-06-243-12/+5
|
* bsp/virtex: Add console devices only if presentSebastian Huber2013-06-241-10/+11
