* bsps/xilinx-zynqmp: Avoid constant UART reinitKinsey Moore2021-04-191-0/+6
| | | | | | Constantly reinitializing the Cadence UART on every character output causes data corruption/loss on some ZynqMP hardware. Only initialize the UART once for early output and give it a kick on startup.
* bsps/aarch64: Add support for EL2 startKinsey Moore2021-03-051-0/+25
| | | | | Add the stub necessary to boot on AArch64 under EL2 and drop to EL1 for normal operation.
* bsps/aarch64: RTEMS_DEBUG stack alignment faultsKinsey Moore2021-03-051-0/+8
| | | | | | Run with stack alignment faults enabled under RTEMS_DEBUG to catch any stack misalignments early. This makes it easier to track them down should they ever occur.
* bsps: Allow override of ARM TM27 IRQsKinsey Moore2021-03-051-0/+8
| | | | | | ZynqMP hardware appears to have an odd hard-wired SGI implementation in which the SGIs are permanently set as enabled or disabled. Allow the TM27 IRQs to be overridden as necessary.
* bsps/aarch64: Resolve usage of SUBALIGN()Kinsey Moore2021-03-051-4/+2
| | | | | | | | Remove usage of SUBALIGN() in aarch64 linkcmds which works around a difference in behavior on AArch64 platforms. This is no longer necessary since alignment is now enforced explicitly. Closes #4178.
* bsps/aarch64: Add missing includeSebastian Huber2021-01-281-0/+1
| | | | | | | | | Fixes: bsps/shared/dev/irq/arm-gicv2.c:53:6: warning: no previous prototype for 'bsp_interrupt_dispatch' [-Wmissing-prototypes] Close #4227.
* bsps: Add missing DWARF 5 sectionsSebastian Huber2021-01-261-3/+5
| | | | Sort alphabetically.
* bsps: Support DWARF 5 sectionsSebastian Huber2021-01-251-8/+13
| | | | GCC 11 uses DWARF 5 by default.
* bsps/aarch64: Swap primary ZynqMP UARTKinsey Moore2021-01-142-4/+4
| | | | | Both Qemu and actual hardware treat the second UART in memory map as the primary UART. This adjusts the ZynqMP BSPs to match.
* bsps: Use header file for GIC architecture supportSebastian Huber2020-12-231-3/+17
| | | | | | This avoids a function call overhead in the interrupt dispatching. Update #4202.
* bsps: Fix includesSebastian Huber2020-12-221-1/+0
| | | | Update #4202.
* bsps: Remove gicvx_interrupt_dispatch()Sebastian Huber2020-12-161-5/+0
| | | | | | Avoid one level of indirection. Update #4202.
* Add AArch64 ZynpMP BSPKinsey Moore2020-12-046-0/+426
| | | | | | | | This adds a BSP family that runs on the Xilinx Ultrascale+ MPSOC (ZynqMP) family of chips. It is configured to be usable on the Qemu ZCU102 machine definition and should be almost trivially portable to ZynqMP development boards and custom hardware. It is also configured to be usable with libbsd.
* bsps: Move ARM GICv2 driver to bsps/sharedKinsey Moore2020-12-021-1/+1
| | | | | This moves the ARM GICv2 driver to bsps/shared to be usable by AArch64 code.
* spec/aarch64: Only apply SUBALIGN(4) to ILP32Kinsey Moore2020-11-231-2/+4
| | | | | | | The SUBALIGN(4) required on rtemsroset and rtemsrwset for ILP32 builds was previously present on LP64 builds and causes no issues within RTEMS, but causes relocation/alignment issues when building libbsd. This restricts those alignment changes to ILP32 builds.
* bsps: Add Cortex-A53 ILP32 BSP variantKinsey Moore2020-10-051-0/+16
| | | | | | This adds an AArch64 ILP32 BSP variant based on Qemu's Cortex-A53 emulation with interrupt support using GICv3 and clock support using the ARM GPT.
* bsps: Add Cortex-A53 LP64 basic BSPKinsey Moore2020-10-0513-0/+2137
This adds an AArch64 basic BSP based on Qemu's Cortex-A53 emulation with interrupt support using GICv3 and clock support using the ARM GPT.
