Sparc - Leon - New driver creation

[Yannick SARTHOU]

Ok I agree, in this particular an simple API will do the job fine but I 
still wanted to know if it is possible to register a "soft device" (more 
complicated than my simple MRAM register) to link with a driver or if it 
has to be linked with a hardware device ?
