your logs shows everything OK. But don't know about LED's glowing. anyhow you can log in to your board and you can try experimenting what you want.
By seeing logs what i can say is, u-boot, kernel image and rootfs all are loaded well, no problem with those images. so don't worry about those LED's, you start your next task.
