Several bugfixes have occurred upstream since this script was imported into U-Boot.
In particular, the script currently in U-Boot does not correctly decode the localversion for commit f8bbb4dad0e9d91b7a51d6cc54dcf66d142f50fe, because "git name-rev --tags HEAD" gives this: HEAD tags/v2011.12-rc1~30^2
Then this regex does not match because of the trailing '^2': grep -E '^HEAD[[:space:]]+(.*~[0-9]*|undefined)$'
The kernel has a bit of extra support for CONFIG_LOCALVERSION set up in a ".config" file which is unnecessary in U-Boot, so it isn't exactly identical, but it is very close to the version in Linux v3.2-rc4.
