Here is an example from the device tree configuration on my system:
bootargs = "dom0_mem=320M console=dtuart
dtuart=/soc/serial@e6540000 dom0_max_vcpus=2 loglvl=all xsm=flask
flask=permissive bootscrub=0 console_timestamps=boot scmi_smc_passthrough";
xen,dom0-bootargs = "root=/dev/ram0 console=hvc0
ignore_loglevel clk_ignore_unused";
I have referred to the dom0_mem property as a guide.
I will update scmi_smc_passthrough to scmi-smc-passthrough
