[U-Boot] define dynamic localversion

Hi,

in linux-kernel i can set a dynamic localversion appended to uboot-version

looking in scripts/setlocalversion line 161 seems to look the same

res="${res}${CONFIG_LOCALVERSION}${LOCALVERSION}"

so i tried this:

gitbranch=$(git rev-parse --abbrev-ref HEAD) export LOCALVERSION="-${gitbranch}" make;

should append my current git-branch to uboot's version...but i have only a + added (git repo dirty because i did not committed these changes yet)

i have defined

CONFIG_LOCALVERSION_AUTO=n

for testing to drop commit-id

any idea?

regards Frank
