I would like to be able to identify the u-boot version from linux. At first this seemed straight-forward, simply enable CONFIG_VERSION_VARIABLE and use fw_printenv in linux.
This, of course, doesn't work, as 'ver' is not saveenv'ed and fw_printenv just pulls the info from flash (or whereever). Writing a routine in the board init file (last_stage_init) doesn't help, as 'ver' is set after that is run and therefore the stored version string is the old one (if an update occurs).
So this is a 2 part question... What good is the 'ver' env var? It's apparently only useful in u-boot itself and u-boot already has a 'version' command that gives you the same info. And second, I'm sure I'm not the first person to want to see u-boot version in linux, so how have other accomplished this?
Thanks, Zach
