* score: Rename _ISR_Disable() and _ISR_Enable()Sebastian Huber2016-05-201-2/+2
| | | | | | | | | Rename _ISR_Disable() into _ISR_Local_disable(). Rename _ISR_Enable() into _ISR_Local_enable(). Remove _Debug_Is_owner_of_giant(). This is a preparation to remove the Giant lock. Update #2555.
* score: Add CPU_MAXIMUM_PROCESSORSSebastian Huber2016-03-041-0/+2
| | | | Maximum number of processors of all systems supported by this CPU port.
* or1k: Delete superfluous _CPU_Null_fp_contextSebastian Huber2016-02-171-17/+1
| | | | Update #2559.
* score: Introduce CPU_CACHE_LINE_BYTESSebastian Huber2016-01-261-21/+3
| | | | | Add CPU_CACHE_LINE_BYTES for the maximum cache line size in bytes. The actual processor may use no cache or a smaller cache line size.

| | | | | 4e3d9a4d6c76fba8e31138d503f736405dafc213 broke or1k, cpuatomic.h has to be added to all architectures.

* or1k fix bug: Initialize thread context with higher stack address.Hesham ALMatary2014-09-291-2/+3
| | | | | | Since or1k architecture stack grows down, threads should be initialized with high stack addresses instead of lower ones. This is done in _CPU_Context_Initialize function.
* score/cpu/or1k: Follow no_cpu ISR_Handler algorithm.Hesham ALMatary2014-09-161-0/+10
| | | | | | | | This patch adjusts ISR_Handler to exactly follow the pseudo code introduced in http://rtems.org/onlinedocs/doc-current/share/rtems/html/porting/Interrupts-Interrupt-Dispatching.html It adds two new checkings on _Thread_Dispatch_disable_level and _ISR_Nest_level after returning from the C handler.
* OpenRISC: Account for red-zone (fixup printf bug).Hesham ALMatary2014-09-162-19/+22
| | | | | | | | | | | | | | This patch allocate a space in the stack to account for red-zone that gcc may utilize for the use of leaf functions. Care must be taken to handle this red-zone from many places: 1- Upon creation of a new thread stack. 2- Once an interrupt entred. Also moving the enable-thread-dispach() and increment ISR level before checking if dispatch needed was required. The previous modifications solved the printf bug which disabled ticker to output strings after context switches that arise from Thread_Delay_ended.
* or1k: Let CPU/BSP Fatal handler have access to sourceHesham ALMatary2014-09-101-2/+2
| | | | | | This patchs follows the latest commit by Daniel Hellstrom that requires _CPU_Fatal_halt to have _source passed to it along with _error number.
* Regenerate preinstall.am for score/cpu/or1kHesham ALMatary2014-09-041-3/+3
| | | | | This patch regenerates preinstall.am file after Chris fixup regarding preinstall.am files gerenration from bootstrap -p command.
* or1k: Implement context validate and context volatile clobber functions.Hesham ALMatary2014-09-024-3/+225
| | | | | | score/cpu/or1k: Add two new assembly functions: _CPU_Context_validate and _CPU_Context_volatile_clobber; their implementation follows corresponding ARM functions.
* Add missing r31 load instruction _ISR_HandlerHesham ALMatary2014-09-021-0/+1
| | | | | _ISR_Handler: r31 was not loaded in restore function. This patch adds this load.
* Add or1k tick timer register definitionsHesham ALMatary2014-08-181-2/+14

* or1k/.../preinstall.am: Add missing fileJoel Sherrill2014-08-121-0/+49

* Add support for OpenRISC - Fixed issuesHesham ALMatary2014-08-1213-0/+2261
This work is based on the old or32 port (that has been removed back in 2005) authored by Chris Ziomkowski. The patch includes the basic functions every port should implement like: context switch, exception handling, OpenRISC ABI and machine definitions and configurations.
