hi Andrew !

thanks for your help. concate of two flashes works now, i dont have tested if 
it all works when there is a image or kernel on both flashes splited but i 
will do it when i have more time and i think there should not be a big 
problem because of mmu-mapping them contiguous.

thanks a lot, greetings from tyrol,
regards manfred
