Tested: * HDMI * MMC * eMMC (mounted) * NAND (kernel log - no partitions) * RTC * USB-Host * Ethernet * WiFi * Bluetooth * serial console Open: * HDMI sound * Onboard sound (ALSA looks good has no phones connected yet) * User-Button * USB-OTG Cannot test: * CAN Additional comments: 1. The way, the dt-files are copied into the kernel sources is not state of the art. But since this is some work in progress it makes my worklow a lot easier. 2. My target is to send dt-files to mainline kernel but they are not yet ready for that 'environment'. Once done I'll send backports to meta-fslc and 1. can go.
