[U-Boot] git setlocalversion

[Derek Ou]

Our company uses svn for the source code management but I use git 
locally to track
my development.  When I build U-boot, it always complains about "fatal: 
cannot
describe" the SHA1 # of HEAD.  It goes back to line 16 of 
tools/setlocalversion.

I know that the error will go away when I tag my git HEAD.  But what is the
philosophy of this setlocalversion?  Should I always tag the top commit 
of my
git tree to maintain a clean U_BOOT_VERSION define?
