Hello Wolfgang,

Wouldn;t it be better, if u-boot fixes the device tree entries?
I think, u-boot should know, where the flash begins and ends, and
because this is maybe a dynamic variable for this board, it should
be better, if u-boot fixes this, so no need for adding a device tree
for every board variant.

Heiko
