From d498630ea9a5880302ee941f28925ee231b8f018 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 9 Jul 2020 18:39:36 -0600 Subject: [PATCH] binman: Add an etype for external binary blobs It is useful to be able to distinguish between ordinary blobs such as u-boot.bin and external blobs that cannot be build by the U-Boot build system. If the external blobs are not available for some reason, then we know that a value image cannot be built. Introduce a new 'blob-ext' entry type for that.
