From e641d796b5ca790f53ddcb885bdbaed1642e4544 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 9 Oct 2008 17:22:22 -0600 Subject: [PATCH] OMAP2xxx: move SRAM to fix boot hang MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 1c957036bbd912322793da676d05e169abf24782 breaks booting on OMAP2; it causes the SRAM to be mapped on top of the L4 interconnect. This causes the system to hang early in boot in omap_map_sram() during the TLB flush. Fix by moving SRAM elsewhere in the memory map. Reported by Jarkko Nikula . This patch is a collaboration with Tony Lindgren and Kevin Hilman . Boot-tested on 2430SDP (by Paul) and N810 (by Jarkko).
