What U-Boot are you using? I would think that has more to do with not booting from SD card than Manjaro.
I expect that the first thing you'll want to do is install one of the non-Google market apps. That should get you closer to what you're probably expecting for usability. Otherwise you might need to install Google Play Services or something like it.
