From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Fri, 6 Dec 2019 21:42:24 -0700 Subject: [PATCH v6 051/102] x86: Add an option to include a FIT In-Reply-To: <20191207044315.51770-1-sjg@chromium.org> References: <20191207044315.51770-1-sjg@chromium.org> Message-ID: <20191206213936.v6.51.I8927290f40075722d16217b170ef701463930bfd@changeid> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Many Intel SoCs require a FIT in order to boot properly. Add an option to include this and enable it by default. This term can be confused with FIT (Flat Image Tree) in U-Boot so the CONFIG option has to include 'X86'.
