The DDR firmware binaries are not part of the U-Boot source code, so we should look for them in the build directory, where they need to be copied to before building U-Boot. The ATF binary is already fetched from the build directory, but the README files for the i.MX8M EVKs claim that it needs to be copied to the source directory (which is still true for in-tree builds, but not in general). Therefore we also fix the READMEs to use the build directory as the correct location for all additional binary files. Sined-off-by: Frieder Schrempf <frieder.schrempf@kontron.de>
