From: Yanjiang Jin <yanjiang.jin@windriver.com> I guess socfpga's other boards may need this patch, but I have Arria10 board only. So add a new function socfpga_a10_cpu_kill(), keep the old function socfpga_cpu_kill() for other boards. I also verified CPU_HOTPLUG after applying this patch, everything seems well. Test steps: 1. Enable kexec and build a SOCFPGA kernel; 2. Use zImage as 1st and 2nd kernel; 3. kexec -l /root/zImage --append="`cat /proc/cmdline`" 4. kexec -e Test env: U-Boot 2014.10 (Jan 13 2016 - 11:07:09) CPU : Altera SOCFPGA Arria 10 Platform BOARD : Altera SOCFPGA Arria 10 Dev Kit -- 1.9.1
