2018-03-19bsps/powerpc: Move exceptions support to bspsSebastian Huber1-187/+0
This patch is a part of the BSP source reorganization. Update #3285.
2016-11-18powerpc: Add up to date CPU_Interrupt_frameSebastian Huber1-216/+0
Rename ppc_exc_min_frame to CPU_Interrupt_frame. Move it and the corresponding defines to <rtems/score/cpuimpl.h>. Update #2809.
2015-01-13powerpc: AltiVec and FPU context supportSebastian Huber1-0/+148
Add AltiVec and FPU support to the Context_Control in case we use the e6500 multilib. Add PPC_MULTILIB_ALTIVEC and PPC_MULTILIB_FPU multilib defines. Add non-volatile AltiVec and FPU context to Context_Control. Add save/restore of non-volatile AltiVec and FPU to _CPU_Context_switch(). Add save/restore of volatile AltiVec and FPU context to the exception code. Adjust data cache optimizations for the new context and cache line size.
2015-01-09bsps/powerpc: ppc_exc_initialize_interrupt_stack()Sebastian Huber1-11/+1
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2014-02-19score: Add RTEMS_FATAL_SOURCE_BSPSebastian Huber1-2/+2
Merge RTEMS_FATAL_SOURCE_BSP_GENERIC and RTEMS_FATAL_SOURCE_BSP_SPECIFIC into new fatal source RTEMS_FATAL_SOURCE_BSP. This makes it easier to figure out the code position given a fatal source and code.
2014-02-19powerpc: Change interrupt disable implemetationSebastian Huber1-3/+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.
2013-06-21bsps: Move bsp_generic_fatal_code to new fileSebastian Huber1-5/+2
Add bsp_generic_fatal().
2013-06-21bsps/powerpc: Delete bsp_exceptions_in_RAMSebastian Huber1-27/+34
Delete ppc_exc_vector_base. Add and use ppc_exc_initialize_with_vector_base().
2013-02-06bsps/powerpc: Add and use ppc_cpu_is_specific_e200Sebastian Huber1-2/+5
2012-12-03bsps/powerpc: Add PPC_EXC_CONFIG_BOOKE_ONLYSebastian Huber1-1/+7
In combination with the PPC_EXC_CONFIG_USE_FIXED_HANDLER option this removes all dependencies on valid read-write data. The exception handling must be statically configured and all components reside in read-only sections.
2012-11-27powerpc: Add CPU_Exception_frameSebastian Huber1-0/+68
The powerpc port uses now a unified CPU_Exception_frame. This resulted in a CPU_Exception_frame layout change for the MPC5XX.
2012-11-15bsps/powerpc: Exception initialization error is fatalSebastian Huber1-7/+14
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.
