From: Simon Glass Date: Fri, 19 May 2017 02:09:04 +0000 (-0600) Subject: dm: core: Implement live tree 'read' functions X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=47a0fd3bad3858ae2f58bc3b3368e16ed20f394c;p=u-boot.git dm: core: Implement live tree 'read' functions When the live tree is supported some functions need to change a little. Add an implementation which is used when not inlining these functions.
