Strange, I don't think I'm supplying that window size anywhere, so it must 
be some preset range by Axis. I just took a look at the output of a device 
with a smaller Flash and it was the same window.

Both kernelconfig files have the following settings for the Flash:
CONFIG_ETRAX_FLASH_BUSWIDTH=2
CONFIG_ETRAX_FLASH1_SIZE=8

The kernelconfig for Linux 2.6 also adds CONFIG_ETRAX_NANDFLASH_BUSWIDTH, 
which was set to 1. I didn't think it would matter, since we don't have 
NAND Flashes, just NOR ones. I set it to 2 as well, just to see what 
happens, but I still have the same behaviour.

To be totally sure, I changed the FLASH_BUSWIDTH to 1 and still have the 
same effects. It's a bit strange, I didn't expect it to work at all.

It still bugs me that I cannot find the command sequence that is used in 
do_write_buffer() in my Atmel documentation.
