From 1e35a4d2282329093ae384bfbb8df844e23798c6 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 13 Jan 2021 20:29:57 -0700 Subject: binman: Allow reading entries from a subnode Some images may have multiple copies of the same thing, e.g. two versions of the read/write U-Boots. It is necessary to read data from one or other of these under selection of the verified-boot logic. Add a function to select the subnode to use.
