I have executed "makesd -u", but there will still be errors about
"--in-order", and after manually modifying "makesd", then run
"DEV=/dev/sdf ./makesd -v latest ci20 -r https://download.goldelico.com/letux-debian-rootfs/stable-mipsel-quantumstep.tbz"
again, there will still be errors about "Start sector 62929920 out of range".

I have made patches based on 5.13-rc6, but I want to know whether
it will work properly after adding a compatible string about JZ4730
to the previous irq driver, so that I can check whether the changes
I made in the new patch are valid.
Thanks and best regards!
