From: Wang Quanyang <quanyang.w...@windriver.com> Once use kexec in arm arch, it will throw out the error info as below: Could not find a free area of memory of 0xc78e744 bytes... This is because that kexec use kexec_file_load to load image by default but arm doesn't support it. So add this patch to avoid use kexec_file_load in arm platforms.
