From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tom Rini Date: Thu, 25 Apr 2013 13:40:22 -0400 Subject: [U-Boot] [PATCH] arm: Enable -ffunction-sections / -fdata-sections / --gc-sections Message-ID: <1366911622-6566-1-git-send-email-trini@ti.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de While other architectures have enabled these gcc / ld options for some time on U-Boot itself, ARM has only been doing this on SPL. Enable this on full U-Boot as well now.
