From d73420e4fe7c7e22a41ed140c6be9c11db6b9503 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 17 Jan 2023 10:48:06 -0700 Subject: bootstd: Use hunters when scanning for bootflows Add a flag to control whether hunters are used when scanning for bootflows. Enable it by default and tidy up the flag comments a little. Fow now this has no effect, until a future patch enables this feature.
