[U-Boot] fatload accepting wildcard in filename?

Hi,

I came across this page http://boundarydevices.com/upgradeU.php where the linked Xenon "upgrade package" contains a script that does

if fatload mmc 0 80008000 u-boot-xenon*.bin ; then ...

Their release is from a few years back (2008-06-11); the same fatload + wildcard construct doesn't work with 2011.03. I'm trying to find out how this was implemented, and if it was ever part of mainline or if it was a local hack. (I couldn't find it in the ml archives.)

Thanks, Orjan
