Normally users use +* XScuGic instance and call XScuGic_Enable or +* XScuGic_Disable to enable/disable interrupts. These +* new macros are provided when user does not want to +* use an instance pointer but still wants to enable or +* disable interrupts. +* Function prototypes for functions (present in newly +* added file xscugic_hw.c) are added. +* 1.03a srt 02/27/13 Moved Offset calculation macros from *_hw.c (CR +* 702687). +* 1.04a hk 05/04/13 Fix for CR#705621. Moved function prototypes +* XScuGic_SetPriTrigTypeByDistAddr and +* XScuGic_GetPriTrigTypeByDistAddr here from xscugic.h +* 3.0 pkp 12/09/14 changed XSCUGIC_MAX_NUM_INTR_INPUTS for +* Zynq Ultrascale Mp +* 3.0 kvn 02/13/14 Modified code for MISRA-C:2012 compliance. +* 3.2 pkp 11/09/15 Corrected the interrupt processsor target mask value +* for CPU interface 2 i.e. XSCUGIC_SPI_CPU2_MASK +* 3.9 mus 02/21/18 Added new API's XScuGic_InterruptUnmapFromCpuByDistAddr +* and XScuGic_UnmapAllInterruptsFromCpuByDistAddr, These +* API's can be used by applications to unmap specific/all +* interrupts from target CPU. It fixes CR#992490. +* 3.10 aru 08/23/18 Resolved MISRA-C:2012 compliance mandatory violations +* 4.1 asa 03/30/19 Removed macros for XScuGic_EnableIntr, and +* XScuGic_DisableIntr. These are now C functions. This +* change was to fix CR-1024716. +* 4.1 mus 06/12/19 Updated XSCUGIC_MAX_NUM_INTR_INPUTS for Versal. +* 4.6 sk 06/07/21 Delete the commented macro code to fix the MISRA-C warning. +* 4.6 sk 08/05/21 Fix Scugic Misrac violations. +* 4.7 sk 12/10/21 Update XSCUGIC_SPI_INT_ID_START macro from signed to unsigned +* to fix misrac violation. +* 4.7 mus 03/17/22 GICv3 coupled with A72 has different redistributor for +* each core, and each redistributor has different address, +* Updated #define for re-distributor address to have correct +* value based on the cpu number.
