AW: [oc] ARM Equivalent instructions of IN and OUT in x86

["Thilo Jeremias" <jeremias@optushome.com.au>]

All IO on the arm is memory mapped,

you write 8b/16b or word quantities to the desired io-port.

See the relevant ARM (the implementation you are using), docs for
information on where to find the IO-PORTS.

in <-> ld reg,addr (32bit)
ins <-> ldb .... (8bit)

See the arm docu

Nice:
'C'
volatile unsigned long *mem= ...addr...

will do I/O in C

cheers
