OK - so you have  several  configurations,  which  require  different
environment settings. Right?

You can have several (default) configuration stored  simply  in  your
board's  config  file and select these for example by using different
Makefile targets.

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"
