Hello,
I'm trying to compile the linux kernel (SDK 2.0) with no SMP support, since I intended to run it just on one CPU.
I disabled CONFIG_SMP in menuconfig, after that compilation fails with the following error message
CC arch/powerpc/sysdev/fsl_rcpm.o
CC arch/powerpc/sysdev/fsl_lbc.o

Does anybody knows what other step has to be taken in order to compile the linux kernel with no SMP support?
Many thank in advance,
