      Dear Robert,
nice to meet you again here on the mailing list!
In message E1DVbQ7-0003Yf-9J@sc8-sf-mx2.sourceforge.net you wrote:

Yes.

Can the version string be passed or stored so that an application running
under Linux can read it?
Yes. Enable the CONFIG_VERSION_VARIABLE option in your  baord  config
file  (include/configs/atc.h);  then  there  will find an environment
variable "ver" holding the version string. Make sure to run "saveenv"
in U-Boot at least once so that this automatic variable  gets  stored
in flash, too.
Under Linux, you can then use the code from tools/env/ to access  the
U-Boot envrionment and read that variable.
Best regards,
Wolfgang Denk
