vices with same names in the system
and it brakes my IDT NTB driver from being loaded =) So I developed a simple
algorithm of NTB devices naming. Particulary it generates names "ntbS{N}" for
synchronous devices, "ntbA{N}" for asynchronous devices, and "ntbAS{N}" for
. Then driver initialize the outbound memory
windows (outwndw{N}). The read/write operations can be performed using the
following debug nodes:
/sys/kernel/debug/ntb_mw_test/ntbA{N}/inwndw{N}
/sys/kernel/debug/ntb_mw_test/ntbA{N}/outwndw{N}

This macro substitution is the shortcut to map cacheable IO memory
with coherent and write-back attributes. Since it is entirely unused
by kernel, lets just remove it.
