Hi Stefan,
This means that the old spl/u-boot-spl.bin is gone for AT91 and NAND ?

This means that before this patch, there was no special target for AT91
? Thus no special image was built ? And after this patch, there will
also be a new binary u-boot-with-spl.bin, except spl/boot.bin and
spl/u-boot-spl.bin ?
Thus your patch does a bit more than what it's explained in the commit
message ?
Thanks,
Eugen
