## Summary This adds PROTECTED mode support for QEMU emulated Cortex-R5 processor with sample config `qemu-armv7r:pnsh`: - It started with linker script name aligning with ELF programs. - Then a few build issue were fixed for armvr-r code base. - Then chip level support for CHIP_QEMU_CORTEXR5 was added. - Then board support for `qemu-armv7r:pnsh` was added, result a bootable build. - Then SYS_task_start issue is fixed so that hello app can finish smoothly. - then heap sizes were adjusted so that to run ostest program. - Then ARM_THUMB option is added to pass ostest, this is spotted with the great help of @hujun260. To run this sample, a slightly tweaked QEMU is needed, you can get it from [my github](https://github.com/yf13/qemu/tree/arm-virt-r-profile). If you are using Ubuntu 22.04 on amd64 architecuture, you can also grab this [prebuilt binary](https://gitee.com/yf1972/filexfers/releases/download/v9.2-u2204/qemu-armv7r-ubuntu.2204.tar.bz2). ## Impacts Only added sample for armv7-r protected mode, should not affect other targets. ## Testing - checked locally with qemu-armv7r:pnsh, qemu-armv7r:nsh - CI checks. -- This is an automated message from the Apache Git Service.
