Subject: [PATCH 32/45] sandbox: Support obtaining the next phase from an image
Date: Sun, 25 Sep 2022 09:02:35 -0600 [thread overview]
Message-ID: <20220925150248.2524421-33-sjg@chromium.org> (raw)
In-Reply-To: <20220925150248.2524421-1-sjg@chromium.org>
At present sandbox runs the next phase from discrete executables, so for
example u-boot-tpl runs u-boot-vpl to get to the next phase.
In some cases the phases are all built into a single firmware image, as is
done for real boards. Add support for this to sandbox.
Make it higher priority so that it takes precedence over the existing
method.
