Hi Krzysztof,

Thanks for your quick reply!

In that case you used an initrd, right? I see various cases of USB
built-ins, like CONFIG_USB_STORAGE=y, CONFIG_USB_DWC2=y and so on in
multi_v7_defconfig. So my impression was that multi_v7_defconfig was
supposed to allow booting a rootfs from a USB storage device even
without an initrd.

Let me know if that impression is wrong though, I'll happily resend
(and test) the patch with CONFIG_USB_HSIC_USB3503=m then :-).

Regards, Linus
