Enable the user to override the bootargs for domU
The user can specify the bootargs for domU in the config file as
follows:-
DOMU_CMD[x]="<cmd line params>"
As an example,
DOMU_CMD[0]="console=ttyPS0 earlycon console=ttyPS0,115200
console=ttyAMA0 clk_ignore_unused rdinit=/sbin/init root=/dev/ram0
init=/bin/sh"
If the user does not specify this, then the default command line param is:-
"console=ttyAMA0"
Also, updated the README.md.
