But I'm mounting it from userspace (using builtin initramfs inside
zImage), with a poll loop that waits for a device to appear. Maybe if you
do it from kernel you need to use root wait/delay etc. options?

yeah, rootwait should do it.

No, rootwait does not solve it. Try it. Tested many times. (And yes,
you need to actually fool the rear cover sensor or close the phone.)

yeah, just put a magnet or, if you have spare back covers, cut one so
that you "close" it, but still allow you to put the thing on a
development jig.

Actually, it should be enough to kill a line from dts somewhere, no
need to hack hardware for this.

right

Also, if why doesn't rootwait work ? You never have a new mmc node or is
the mmc node changing names ?

IIRC node and name are ok, but the mount just fails. As I don't have

really weird. Specially since it works when you mount afterwards.

"development jig", I lack serial console and this kind of debugging is
not easy.

see if this helps:
