Hi guys,

I's like to ask a couple of quick questions to clear a disagreement we have at the office.

Is the file fw_env.config needed during compilation time to build u-boot?

No.

Or is it in fact only needed at runtime by the tools fw_printenv/saveenv?

MTD setup in /etc/fw_env.config can be used by fw_printenv/saveenv, but it depends on compile configuration of these tool(s). fw_printenv can be compiled with integrated mtd setup and will then not parse the configuration file. But yes, the default is to have an /etc/fw_env.config which describes the mtd setup for u-boot environment. At least this is the case for distributed versions like in Debian.
