From ad1ecd2063dae55ccfca994a7c9fdec2462b18ab Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 31 Jan 2016 18:10:50 -0700 Subject: fdt: Build a U-Boot binary without device tree At present u-boot.bin holds the plain U-Boot binary without the device tree. This is somewhat annoying since you need either u-boot.bin or u-boot-dtb.bin depending on whether device tree is used. Adjust the build such that u-boot.bin includes a device tree (if enabled), and the plain binary is in u-boot-nodtb.bin. For now u-boot-dtb.bin remains the same. This should be acceptable since: - without OF_CONTROL, u-boot.bin still does not include a device tree - with OF_CONTROL, u-boot-dtb.bin does not change The main impact is build systems which are set up to use u-boot.bin as the output file and then add a device tree. These will have to change to use u-boot-nodtb.bin instead. Adjust tegra rules so it continues to produce the correct files.
