From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Herring Date: Thu, 28 Jun 2012 08:54:11 -0500 Subject: [U-Boot] [PATCH 2/2] ARM: increase lmb stack space reservation to 4KB Message-ID: <1340891651-17618-2-git-send-email-robherring2@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Rob Herring The bootm initrd image copy to ram can collide with the stack in cases where the print buffer size is large (i.e. 1K). The result is intermittent initrd decompression errors depending on the initrd size MOD 4KB since the initrd start address is 4KB aligned.
