1. After uboot startup, set the command line parameter to pass to the linux kernel including console=ttyLP0,115200 in
boootargs. For deploy the ramdisk as rootfs, the bootargs can be set as: "set bootargs root=/dev/ram0 rw
console=ttyLP0,115200"
=> set bootargs root=/dev/ram0 rw console=ttyLP0,115200
