Arnaud has spotted that my kernel config was missing CONFIG_SERIAL_OF_PLATFORM
which is why I was getting no output from it. After fixing that I've got a
working system, therefore
Tested-By: Adam Baker <linux at baker-net.org.uk>
I have verified that all of the LED options work, that the reset and OTB
buttons generate the expected codes (I think the reason Iomega chose odd SW_
values is simply those are the first 2 defined values in linux/input.h) and that
the mtd partitions start at the correct offsets for what they claim to contain
(although the last one might make more sense called root rather than boot).
I've verified that the WLAN interface works but not tested wired ethernet.
Unfortunately CONFIG_SERIAL_OF_PLATFORM has dependencies so it wouldn't be a
good idea for CONFIG_MACH_ICONNECT_DT to select it. There could be some value
in it making the default value for CONFIG_SERIAL_OF_PLATFORM=y.
