I think you were right. 
I just bricked it.
I can not even see the U-Boot anymore.
I typed
tftpboot 0x80060000 factory.bin
erase 0x9f000000 +filesize
cp.b 0x80060000 0x9f000000 filesize
bootm 0x9f010000
I guess I should have typed
tftpboot 0x80060000 factory.bin
erase 0x9f010000 +filesize
cp.b 0x80060000 0x9f010000 filesize
reset
