[ECOS] -- MPC8248 port

[anoop r]

yes, cpm_mux_cmxsmr for the SMC devices, cpm_mux_cmxscr for SCC, checked it.
now i used another board of the same config but with linux and its working.
No, no hardware handshaking.
As you said, i tried with the rattler port and the same things happening
here.

thanks.
