You might find logging onto the Neuros OSD SVN and downloading their

Hi Guys,
I have a little question, I am sure will be easily answered. I am
currently trying to access certain I2C devices, such as the AIC33, by
opening up the /dev/I2C/0 port.
This does not seem to want to work, as I assume the AIC33 driver is
somehow locking communications to this I2C device.
Hi,
look in the kernel source /char/rtc-davinci.c
everything you need should be in there.

Through my own tests, I find a large uncompressed image copy is way way

It is worth doing if you can fit it in your NOR. (make sure you se cp.l

The main 'problem' is that a bit-bang driver takes CPU time while the
hardware version should be faster. But with a transfer of 100 us per
byte the overhead of an IRQ driven system is about the same.
