Disassembler location

[Michael Morrell]

I'm working on a port to a new architecture and was noticing a discrepancy in 
where the disassembler code lives.  There is a file "target/<arch>/disas.c" for 
4 architectures (avr, loongarch, openrisc, and rx), but a file "disas/<arch>.c" 
for 14 architectures (if I counted right).  It seems the 4 architectures using 
"target/<arch>/disas.c" are more recently added so I was wondering if that is 
now the preferred location.  I couldn't find information on this, but I wasn't 
sure where to look.

Any advice?

Thanks,

   Michael
