This is error prone. NAK.
which error?
The load address of a standalone application cannot be known at compile time of the U-Boot image.
Please don't assume that the code / Makefiles etc. of that application is even part of the U-Boot source tree or build system.
Please don't assume that everybody uses the same load addresses.
Please don't asume that all standalone applications running on a system use the same load addresses - there are cases, where several SA apps are simultaneously loaded, etc.
Don't try to be clever when this cannot work.
i dont really see the value in moving the load addr from the u-boot build env to the board env automatically, but moving the definitions from examples/Makefile to the top level $arch_config.mk sounds sane to me. -mike
