From e06a698ae62b9ee5ca98e65be2c90a61464192e6 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 28 May 2024 16:52:18 +0800 Subject: [PATCH] scripts/make_fit: Drop fdt image entry compatible string According to the FIT image source file format document found in U-boot [1] and the split-out FIT image specification [2], under "'/images' node" -> "Conditionally mandatory property", the "compatible" property is described as "compatible method for loading image", i.e., not the compatible string embedded in the FDT or used for matching. Drop the compatible string from the fdt image entry node. While at it also fix up a typo in the document section of output_dtb.
