Hello u-boot-users,
Here is a short patch for the examples/Makefile. This improves reliability in the case of a deficient toolchain.
For example the MontaVista (pro 3.0) ppc_82xx objcopy does not accept srec input, and produces an empty output file which can confuse make.
Yep, I had noticed this long ago too. Why not just add "-I srec" as in the attached?

This patch ensures that the binary image is produced from the elf file and not the srec file, which allows a clean build.

PS. MontaVista have 'no general interest in supporting srec input' because of 'how little information srec files contain'.
