-Pin Multiplex(hwconfig setting)
--------------------------------
-Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex
-via hwconfig, i.e:
-'setenv hwconfig usb2' to enable USB2 and disable eTsec2
-'setenv hwconfig tdm' to enable TDM and disable Audio
-'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz)
- and disable TDM
-'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio
-'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources
- is 11MHz), disable eTsec2 and TDM
-
-Warning: TDM and AUDIO can not enable simultaneous !
-and AUDIO codec clock sources only setting as 11MHz or 12MHz !
-'setenv hwconfig 'audclk:12;tdm' --- error !
-'setenv hwconfig 'audclk:11;tdm' --- error !
-'setenv hwconfig 'audclk:10' --- error !
