* bsps/sparc: Fix cache supportSebastian Huber2017-07-191-4/+9
| | | | | | | Fix infinite loop in rtems_invalidate_multiple_instruction_lines(). Implement this function. Close #3080.
* libchip: Fix format warningSebastian Huber2017-07-191-1/+1

* bsps: Fix warningSebastian Huber2017-07-191-0/+3
| | | | Update #3071.
* bsps/sparc: Add leon3 BSP variantsDaniel Cederman2017-07-1711-5/+134
| | | | | | | | | | | | | | | Rename NGMP to GR740 and add configs for UT699, UT700, and GR712RC The UT699 requires -mcpu=leon as it does not support the CAS instruction provided by -mcpu=leon3. It also requires -mfix-ut699 for errata fixes. UT700 and GR712RC requires the -mfix-ut700 and -mfix-gr712rc flags that have been recently added to GCC's master and 7-branch. Remove -msoft-float from the leon3 config to make the more common case of using the FPU the default. Update #3057.
* sparc: Add assembly workaround for LEON3FT B2BST errataDaniel Cederman2017-07-173-0/+87
| | | | | | | | | | | | | | | This patch adds NOP instructions to prevent instruction sequences that are sensitive to the LEON3FT B2BST errata. See GRLIB-TN-0009: "LEON3FT Stale Cache Entry After Store with Data Tag Parity Error" for more information. The sequences are only modified if __FIX_LEON3FT_B2BST is defined. The patch works in conjunction with the -mfix-ut700, -mfix-gr712rc, and -mfix-ut699 GCC flags that prevents the sensitive sequences from being generated. Update #3057.

| | | | | | | | Implement the Processor_mask via <sys/bitset.h>. Provide _Processor_mask_To_uint32_t() to enable its use in device specific routines, e.g. interrupt affinity register in an interrupt controller. Update #3059.

* bsps: Improve interrupt vector enable/disable APISebastian Huber2017-06-2036-370/+238
| | | | | | 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.

* Remove excessive locking from cache operations.Alexei Pososin2017-06-141-35/+9
| | | | | | | | According to manual, the used operations (Clean Line by PA, Clean and Invalidate Line by PA, Cache Sync) are atomic and do not require locking. Update #3007.

* Simplify TLS support in context switchSebastian Huber2017-06-092-2/+5
| | | | | | There is no need to save the thread pointer in _CPU_Context_switch() since it is a thread invariant. It is initialized once in _CPU_Context_Initialize().
* bsps/arm: Fix ARMv7-M interrupt suppportChristian Mauderer2017-06-071-2/+6
| | | | | | Enable/disable vector routines now check for a valid vector. Without these guards, the enable/disable vector routines will not work with the interrupt server.

* bsp/motorola_powerpc: Fix for Binutils 2.28+Sebastian Huber2017-06-016-0/+6
| | | | | | | | | | There are mismatched sections in the bootloader input: ld: Warning: ticker.exe uses hard float, ticker.ralf uses soft float ld: ticker.exe: compiled normally and linked with modules compiled with -mrelocatable ld: failed to merge target specific data of file ticker.exe Suppress this error explicitly.
* bsps/powerpc: Set output format in linker scriptSebastian Huber2017-06-011-1/+1
| | | | | | Set the proper output format in the linker script for the bootloader. Otherwise the generic linker is used since Binutils 2.28 which does not understand the PowerPC-specific relocations.

* sparc: only define start if it is different from SYM(start)Jacob Hansen2017-05-141-0/+2
| | | | | | | | The SYM define concatenates the input with the compiler set __USER_LABEL_PREFIX__ define. This define appears to be '_' in GCC but empty in Clang. Therefore when compiling with Clang/LLVM 'SYM(start)' and 'start' defines the same symbol, and the compiler complains that the symbol is defined twice.
* sparc: Adjust assembly to improve compability with LLVMJacob Hansen2017-05-145-13/+13
| | | | | | | | | | | | | - All references of %0 changed to %g0 - 'call label,0' changed to 'call label'. According to the sparc specification call does not take any registers - '.seg "text"' changed to '.section ".text"' - the synonym stub is replaced with stb - the synonym stuh is replaced with sth

* leon, grtc: updated overrun condition handlingDaniel Hellstrom2017-05-141-11/+33
| | | | | | | | The following functions now reports to the user that an overrun has occured by returning errno EIO: * grtc_read, on overrun and no more data in the DMA buffer * ioctl(GRTC_IOC_RECV), on overrun and no more frames in the DMA buffer * ioctl(GRTC_IOC_ISSTARTED), EIO is returned on overrun
