Re: [U-Boot] [PATCH v2] Update U-Boot's build timestamp on every compile

Dear Peter Tyser,

In message 1224619693-30738-1-git-send-email-ptyser@xes-inc.com you wrote:

Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile.

  @cmp -s $@ $@.tmp && rm -f $@.tmp || mv -f $@.tmp $@

Please do not do this here. Use a separate target instead.

As you can see, we take care NOT to create a new VERSION_FILE for each build, but only when it eally changed. Your change forces it to change with each build, which we tried to avoid.

Best regards,
