Hello ,
I am compiling a kernel for powerpc. I can successfully compile it if I
dont enable the * Support for console on serial port option in the
config file.But if I enable that option then I get the following error
for make zImage command

.../common/ns16550.c: In function `serial_init':
.../common/ns16550.c:63: error: `XPAR_UARTNS550_0_CLOCK_FREQ_HZ'
undeclared (first use in this function)
.../common/ns16550.c:63: error: (Each undeclared identifier is reported
only once../common/ns16550.c:63: error: for each function it appears
make[2]: *** [../common/ns16550.o] Error 1
make[2]: Leaving directory `/ker/arch/ppc/boot/simple'
make[1]: *** [zImage] Error 2
make[1]: Leaving directory `/ker/arch/ppc/boot'
make: *** [zImage] Error 2

I need the support for console on serial port option enabled.
