Subject: arm: davinci: remove unused watchdog functions
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=6b7e092793b764cec66597504af138504d1ac33f;p=u-boot.git

arm: davinci: remove unused watchdog functions

The davinci_hw_watchdog_ functions are defined but never called from
anywhere. Commit 881ae794b93b ("calimain: remove board") eliminated the
last call to these functions.
