Dear Robert,

nice to meet you again here on the mailing list!

Yes.

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
