The (maximum) size of the image to load is hardcoded into at91bootstrap.
For most boards (including at91sam9m10g45-ek) this is 0x33900 if
loading from DataFlash and 0x40000 if loading from NAND.

So if you didn't modify your at91bootstrap, you should get the same
problem on AT91SAM9M10G45-EK if booting from DataFlash.
