Subject: lmb: Simplify lmb_should_notify usage
X-Git-Url: http://git.dujemihanovic.xyz/img/%7B%7B?a=commitdiff_plain;h=f6fb6a885120187ddcff9489ff84b1405eb132fa;p=u-boot.git

lmb: Simplify lmb_should_notify usage

We never call lmb_map_update_notify() without checking the result of
lmb_should_notify(). Instead of running that function everytime fold it
in there and add the additional flags parameter
