Hi,
I have gone through the kexec syscall implementation in kernel in the view
of mpc83xx processor. Currently, I am testing for mpc83xx based card.
The compile error i got was:
kexec/arch/ppc/Makefile:4: kexec/arch/ppc/libfdt/Makefile.libfdt: No such
file or directory
make: *** No rule to make target `kexec/arch/ppc/libfdt/Makefile.libfdt'.
Stop.
I have commented the rule to include Makefile.libfdt in
"kexec/arch/ppc/Makefile", becuase the rules to compile source files of
libfdt folder are already present in the arch/ppc/Makefile.
then i got following compile error:
/opt/ELDK41/usr/bin/ppc_6xx-gcc -g -O2 -fno-strict-aliasing -Wall
-Wstrict-prototypes -I./include -I./util_lib/include -Iinclude/
-I./kexec/arch/ppc/libfdt -I./kexec/arch/ppc/include -c -MD -o
kexec/arch/ppc/kexec-ppc.o kexec/arch/ppc/kexec-ppc.c
kexec/arch/ppc/kexec-ppc.c:24:31: error: crashdump-powerpc.h: No such file

'add_usable_mem_rgns'
kexec/arch/ppc/kexec-ppc.c:390: error: 'KDUMP_BACKUP_LIMIT' undeclared

kexec/arch/ppc/kexec-ppc.c:390: error: (Each undeclared identifier is

Below is the full dump of configure and make commands.
