No.

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.
