From 2a5bdfc8d524535e78d81f5932fc62a6b34addc6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 5 Feb 2019 16:52:42 +0000 Subject: [PATCH] hw/arm/boot: Clarify why arm_setup_firmware_boot() doesn't set env->boot_info The code path for booting firmware doesn't set env->boot_info. At first sight this looks odd, so add a comment saying why we don't.
