From cfd93465ec9d5e47447564cd4cedabc43390c12b Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Thu, 27 Mar 2025 11:30:27 +0000 Subject: [fdt] Add the concept of an FDT image Define the concept of an "FDT" image, representing a Flattened Device Tree blob that has been downloaded in order to be provided to a kernel or other executable image. FDT images are represented using an image tag (as with other special-purpose images such as the UEFI shim), and are similarly marked as hidden so that they will not be included in a generated magic initrd or show up in a virtual filesystem directory listing.
