Hi,<br><br>I have gone through the kexec syscall implementation in kernel in the view of mpc83xx processor. Currently, I am testing for mpc83xx based card.<br><br>The compile error i got was:<br>kexec/arch/ppc/Makefile:4: kexec/arch/ppc/libfdt/Makefile.libfdt: No such file or directory<br>
make: *** No rule to make target `kexec/arch/ppc/libfdt/Makefile.libfdt'. Stop.<br><br>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.<br>
<br>then i got following compile error:<br>/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<br>
