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.

You might want to take the opportunity to fix the firmware directory name as well.
I will leave this to someone who knows more about this and once someone has decided which version of the firmware should actually be used. Personally I have used 7.8 (from Yocto Warrior release) and 8.1 (from Yocto Zeus release) with my custom i.MX8MM board so far.
The discussion about this is currently also going on here: https://lists.denx.de/pipermail/u-boot/2019-December/393638.html
