From 871aa41d4c9ecf8d89b98491dc86d0097fdf80e5 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 16 Oct 2017 18:08:38 +0000 Subject: x86: provide CONFIG_BUILD_ROM Up to now we depended on an exported variable to build u-boot.rom. We should be able to specify it in the configuration file, too. With this patch this becomes possible using the new Kconfig option CONFIG_BUILD_ROM. This option depends on CONFIG_X86 and is selected in qemu-x86_defconfig and qemu-x86_64_defconfig.
