--- Patch based on the spl patchset from Bo Shen (as I want to collect this function in at91-common directory), see: http://lists.denx.de/pipermail/u-boot/2013-November/166272.html (reworked this against newest Kconfig Makefile changes ... @Bo: Do you plan an update for this patchset for the Kconfig changes?
Maybe my change in arch/arm/cpu/at91-common/Makefile could be done better... Do we have a common define for all this variants?
