Subject: [PATCH 1/2] common: boot: Instantiate storage for global.boot.machine_id
Date: Fri, 14 Jun 2019 20:35:08 +0000	[thread overview]
Message-ID: <20190614203438.18900-2-cory.tusar@zii.aero> (raw)
In-Reply-To: <20190614203438.18900-1-cory.tusar@zii.aero>

There are references throughout the documentation (and elsewhere in the
boot code) regarding the use of machine-id in a bootloader spec file.
However, there was no global storage allocated for this variable.

This commit adds the necessary storage and associated initialization.
