you are using "run ram_root" ?

It is

ram_root=run ramargs addip addtty;bootm ${kernel_addr} ${ramdisk_addr} ${fdt_addr}

according to your bootargs.txt "addtty" is set incorrectly, it
just overwrites "bootargs" again:
addtty=setenv bootargs console=ttyS1.9600

you should fix your "addtty" to be sth. like

"setenv bootargs ${bootargs} console=ttyS1,9600"
