I'm quite sure it's only half of the fix. Isn't is necessary to change 
u-boots bootcmd as well to increase the number of to be read bytes to 3072k?

Please provide some kind of migration guide in the commit message. I'm 
in doubt that only sysupgrading to the changed image is all that's required.

Finally, if you have a migration path, you can enable the default build 
of the P2812HNUF3 image by dropping the "DEFAULT := n".
