[U-Boot] Question about Automatic Updates

[TigerLiu at viatech.com.cn]

Hi, experts:
I found an Automatic Updates digest in this web page:
http://www.denx.de/wiki/view/U-Bootdoc/AutomaticUpdates

So, my question is:
1. Can uboot support this feature now?
   I could not find key word "firmware.img" etc in u-boot source code
package.

Best wishes,
