Subject: [U-Boot] [PATCH v3 17/21] efi_loader: set loaded image code/data type properly
Date: Wed, 13 Sep 2017 18:05:40 -0400 [thread overview]
Message-ID: <20170913220546.19560-18-robdclark@gmail.com> (raw)
In-Reply-To: <20170913220546.19560-1-robdclark@gmail.com>
These should be set according to the image type. Shell.efi and SCT.efi
use these fields to determine what sort of image they are loading.
