From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Frysinger Date: Tue, 28 Jun 2011 15:36:10 -0400 Subject: [U-Boot] [PATCH 01/18] Blackfin: uart: move debug buffers into local bss In-Reply-To: <1309289787-7846-1-git-send-email-vapier@gentoo.org> References: <1309289787-7846-1-git-send-email-vapier@gentoo.org> Message-ID: <1309289787-7846-2-git-send-email-vapier@gentoo.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de There's no need for these saved buffers to be global symbols, or in the data section. So mark them static to move them into the bss.
