Subject: board: bcm96846: Switch to using OF_UPSTREAM
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20.Permalink%20%7D%7D?a=commitdiff_plain;h=25e46f8281075d3b3a8d393264ff1cd33f8815b3;p=u-boot.git

board: bcm96846: Switch to using OF_UPSTREAM

This board clearly develops first in Linux which had more
hardware listed, so let's start to use OF_UPSTREAM.
This makes the NAND driver work.
