Subject: [PATCH] of: error: 'const struct kimage' has no member named 'arch'
Date:   Thu, 18 Feb 2021 14:33:05 -0800

of_kexec_alloc_and_setup_fdt() defined in drivers/of/kexec.c builds
a new device tree object that includes architecture specific data
for kexec system call.  This should be defined only if the architecture
being built defines kexec architecture structure "struct kimage_arch".

Define a new boolean config OF_KEXEC that is enabled if
CONFIG_KEXEC_FILE and CONFIG_OF_FLATTREE are enabled, and
the architecture is arm64 or powerpc64.  Build drivers/of/kexec.c
if CONFIG_OF_KEXEC is enabled.
