I am trying to set xen,dom0-bootargs using the fdt command of U-Boot.
I did have to fight
the double quotes that fdt set was putting in but i managed to fix that.

I did enable the various Xen options including the hvc console in the kernel.

Just before invoking xen, here's what fdt list shows:
U-Boot# fdt list /chosen
chosen {
        xen,dom0-bootargs = "console=hvc0,115200n8 vram=16M
root=/dev/ram initrd=0x83000000,16M ramdisk_size=65536 rw
earlyprintk=xen";
        xen,xen-bootargs = "dom0_mem=256M console=dtuart
dtuart=serial2 earlyprintk=xen";
        modules {
        };
};
U-Boot#

Does this look right?
