From dc4d2a70db40a302cb7001ddbc41816e7187d5c5 Mon Sep 17 00:00:00 2001 From: Tianjie Xu Date: Mon, 16 Dec 2019 16:07:27 -0800 Subject: Move libboot_control to boot_control 1.1 It should belong to the default /misc implementation of boot control 1.1. Right now, it's only used by cuttlefish. So move it over to reduce confusion in bootloader_message.
