There is a bug in the SMC init code, wher the base address for the SMC's
is not reinitialized by the kernel, so if the SMC is not initialized by
the bootloader, it will not work.

If that is the case, try this patch.

Subject: [PATCH] ppc32: Fix baseaddress for SMC 1 and 2

Base addess register for SMC 1 and 2 are never initialized. 
This means that they will not work unless a bootloader already
configured them.
The DPRAM already have space reserved, this patch just makes sure 
the base addess register is updated correctly on initialization.
