Writing to the OCOTP on mx28 boards

[Maxime Ripard]

Hi everyone,

I'm trying to write down some data to the /dev/ocotp file, which is
basically a one time programming chip containing four bytes.

Using the command mw -b -d /dev/ocotp 0-3 0x01020304 writes down only
"4" to the first byte of the OCOTP, which is not quite what I was
expecting. What's the correct syntax for the mw command?

Thanks,
Maxime
