Dealing with new git fetcher

[Gary Thomas <gary@mlbassoc.com>]

The 'git' fetcher was recently changed to expect/need the branch
name for the desired revision.  Many recipes don't have this and
the revision is not on the master branch, hence leading to errors
like this:
   ERROR: Fetcher failure: Unable to find revision f89bc066db0569008418fac1a0408a9a57f2232f in branch master even from upstream
   ERROR: Function failed: Fetcher failure for URL: 'git://github.com/boundarydevices/u-boot-imx6.git'. Unable to fetch URL from any source.
   ERROR: Logfile of failure stored in: /local/imx6_new/tmp/work/sabrelite-amltd-linux-gnueabi/u-boot-script-boundary/v2013.01+gitAUTOINC+f89bc066db-r0/temp/log.do_fetch.25272
   ERROR: Task 144 (/local/poky-multi/meta-fsl-arm-extra/recipes-bsp/u-boot/u-boot-script-boundary_git.bb, do_fetch) failed with exit code '1'

So the problem becomes how to identify the branch?  In the case
above, I have a checked out copy of this repository and when I
try to find the branch, I come up empty:
   $ git branch --contains f89bc066db0569008418fac1a0408a9a57f2232f
   $ git log f89bc066db0569008418fac1a0408a9a57f2232f
   commit f89bc066db0569008418fac1a0408a9a57f2232f
   Author: Eric Nelson <eric.nelson@boundarydevices.com>
   Date:   Mon Aug 26 17:36:35 2013 -0700
       i.MX6: nitrogen6x: Add Yocto boot script

So I see that the commit is present, but when I ask what branch, I
get nothing...

Any ideas how to proceed?

Thanks
