| | | | Update #3090.
* Optional Clock_driver_support_shutdown_hardware()Sebastian Huber2017-08-048-32/+37
| | | | | Make Clock_driver_support_shutdown_hardware() optional. This avoids the atexit() support on memory constrained targets.
* bsps/powerpc: Add PPC_EXC_INTERRUPT_FRAME_SIZESebastian Huber2017-08-015-9/+11
| | | | | | Use a specific define for the interrupt exception frame size. Update #3082.
* bsps/powerpc: Rename ppc_exc_wrap_async_normalSebastian Huber2017-08-014-10/+10
| | | | | | | Rename ppc_exc_wrap_async_normal to ppc_exc_interrupt to avoid a bit of obfuscation. Update #3082.
* bsps/powerpc: Do not set ouput format and archSebastian Huber2017-07-311-4/+0
| | | | | | | | There is no need to explicitly set the output format and architecture in the linker script. This enables the usage of this linker script with the ELFv2 ABI (64-bit). Update #3082.
* bsp/qoriq: Simplify fatal exceptionsSebastian Huber2017-07-318-109/+420
| | | | | | | Avoid use of small-data area, since it is not supported in the ELFv2 ABI by GCC. Update #3082.

* bsp/qoriq: New BSP namesSebastian Huber2017-07-2813-49/+28
| | | | | | | | Due to the FDT support we can now reduce the BSP variants. Use the processor core to define the BSP variants. Update #3082. Update #3085.
* bsp/qoriq: Simplify initializationSebastian Huber2017-07-282-48/+7
| | | | | | | | | Do not flush/invalidate the caches. Instead enable the cache during the low-level initialization and perform an explicit cache flush for the read-only and fast-text sections. Update #3082. Update #3085.
* sparc: Add lazy floating point switchSebastian Huber2017-07-256-13/+203
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPARC ABI is a bit special with respect to the floating point context. The complete floating point context is volatile. Thus, from an ABI point of view nothing needs to be saved and restored during a context switch. Instead the floating point context must be saved and restored during interrupt processing. Historically, the deferred floating point switch was used for SPARC and the complete floating point context is saved and restored during a context switch to the new floating point unit owner. This is a bit dangerous since post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context. The floating point unit is disabled for interrupt handlers. Thus, in case an interrupt handler uses the floating point unit then this will result in a trap (INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT). In uniprocessor configurations, a lazy floating point context switch is used. In case an active floating point thread is interrupted (PSR[EF] == 1) and a thread dispatch is carried out, then this thread is registered as the floating point owner. When a floating point owner is present during a context switch, the floating point unit is disabled for the heir thread (PSR[EF] == 0). The floating point disabled trap checks that the use of the floating point unit is allowed and saves/restores the floating point context on demand. Update #3077.
* INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNITSebastian Huber2017-07-253-0/+12
| | | | | | Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT. Update #3077.
* sparc: Rename SPARC_USE_SAFE_FP_SUPPORTSebastian Huber2017-07-251-3/+3
| | | | | | | Rename SPARC_USE_SAFE_FP_SUPPORT in SPARC_USE_SYNCHRONOUS_FP_SWITCH. Update comment. Update #3077.

* 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.
