While I haven't used a USB video device on an ARM board, I have tried
cross compiling the v4l sources for ARM.  Here's what I found:

The v4l/Makefile.media uses the host strip binary on the ARM .ko files,
which doesn't work.  It could use $(CROSS_COMPILE)strip instead.  I
worked around the problem using a strip soft-link to arm-eabi-strip in
my cross tools bin directory.

The v4l/firmware/Makefile assumes /lib/firmware, this could be
$(DESTDIR)/lib/firmware instead.

Here are the make commands I used to build the v4l tree:

PATH=/path/to/devkitARM/bin:$PATH make ARCH=arm CROSS_COMPILE=arm-eabi-
SRCDIR=/path/to/arm/kernel-src

PATH=/path/to/devkitARM/bin:$PATH make ARCH=arm CROSS_COMPILE=arm-eabi-
DESTDIR=/path/to/arm/sysroot install

I'd like to know if modules built this way work on actual hardware.

Regards.
