Hi again,
Ok, so I tried mapping to in_be32( ) and out_be32( ) by changing:
#define XIo_In32(InputPtr) (*(volatile u32 *)(InputPtr)); SYNCHRONIZE_IO;
to
#define XIo_In32(InputPtr) in_be32(InputPtr)
and
#define XIo_Out32(OutputPtr, Value) \
{ (*(volatile u32 *)(OutputPtr) = Value); SYNCHRONIZE_IO; }
to
#define XIo_Out32(OutputPtr, Value) out_be32(OutputPtr, Value)
I made sure to include asm-ppc/io.h, too. However, I still get the same
unresolved symbol error message... Did I do the mapping correctly?
Thanks again for your help!

Hi,
Thanks for your reply! I am new to creating loadable kernel modules, so
I hope you do not mind some more questions... How can I get the XIo_*
helper routines to compile into the kernel or export them with
EXPORT_SYMBOL( )? In my c file (my driver file from which I create the
object file), I made sure to include xio.h, which is where XIo_In32 and
XIo_Out32 are defined (see below section from xio.h).
Add an EXPORT_SYMBOL() line to the location where the io accessors are
implemented. However, you'd probably be better just to replace xio.h
implementation with macros that just map them to the in_be32() and
out_be32() macros.
