First of all sorry if my question is silly,but I am trying to understand android build process. So, When I checked fstab.freescale for 7ulp evk and sabresd_7d I found following difference in the file.
/devices/platform/40000000.ahb-bridge0/40330000.usb/ci_hdrc.0* auto auto defaults voldmanaged=usb:auto
/devices/soc0/soc/30800000.aips-bus/30b20000.usb/ci_hdrc.1* auto auto defaults voldmanaged=usb:auto
After reading some documentation I understand 40000000.ahb-bridge0/40330000.usb & 30800000.aips-bus/30b20000.usb are the usb otg addresses as given in device tree.
but what I dont understand is:
1. /devices/platform/ in 7ulp and /devices/soc0/soc/ in sabresd_7d
why there is no platform in 7d and extra soc0?
2. usb/ci_hdrc.0 & usb/ci_hdrc.1
why is this difference of 1 and 0 in the files?
can someone please explain me this difference. Your help would be much appreciated.
