The environment for a single board may vary slightly depending on the product it is going into (e.g. different mtdparts kernel bootarg). Our
OK - so you have several configurations, which require different environment settings. Right?
Steven's idea means we can keep the environment in 'source' format and build the binary on the fly.
You can have several (default) configuration stored simply in your board's config file and select these for example by using different Makefile targets.
I might have missed a trick though if this can be done as part of the normal u-boot build?
Add the required definitions to your board config file, and select these as different make targets. See for example tre adjustment of the U-Boot image file name on the TFTP server in "include/configs/TQM5200.h" (search for CONFIG_U_BOOT_SUFFIX), or see the different initialization of the environment depending on flash size (CONFIG_FLASH_8MB) and whether or not the hush shell is activated (CFG_HUSH_PARSER) in "include/configs/trab.h"
