This is a part of patchset where IBM's Flexible Service Interface is
introduced.
The scratchpad provides a set of non-functional registers. The firmware
is free to use them, hardware does not support any special management
support. The scratchpad registers can be read or written from LBUS
slave. The scratch pad is managed under FSI CFAM state.

This is a part of patchset where IBM's Flexible Service Interface is
introduced.
The LBUS is modelled to maintain mapped memory for the devices. The
memory is mapped after CFAM config, peek table and FSI slave registers.
