Steps to Reproduce

1. Build project

$ setup.sh --machines xilinx-zynqmp --templates=feature/kexec,feature/kdump --dl-layers --all-layers --accept-eula=yes
$ source environment-setup-x86_64-wrlinuxsdk-linux 
$ source oe-init-build-env
$ bitbake wrlinux-image-std

2. Load images to the ZCU102 board (#29041)

3. Run the following commands

kexec:
root@xilinx-zynqmp:~# cat /proc/cmdline > args
root@xilinx-zynqmp:~# cp /boot/Image /boot/kernel_kexec
root@xilinx-zynqmp:~# kexec -l /boot/kernel_kexec --append="`cat args`"
root@xilinx-zynqmp:~# kexec -e
 
kdump:
root@xilinx-zynqmp:~# cat /proc/cmdline > args
root@xilinx-zynqmp:~# cp /boot/Image /boot/kernel_kdump
root@xilinx-zynqmp:~# mv /etc/sysconfig/kdump.conf /etc/sysconfig/kdump.orig
root@xilinx-zynqmp:~# kexec -p /boot/kernel_kdump --append="`cat args`"
root@xilinx-zynqmp:~# echo c > /proc/sysrq-trigger
