Subject: [PATCH] OMAP2xxx: move SRAM to fix boot hang
Date: Thu, 09 Oct 2008 17:22:22 -0600 [thread overview]
Message-ID: <20081009232106.13509.80699.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081009232100.13509.6688.stgit@localhost.localdomain>
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 <jarkko.nikula@nokia.com>. This patch is a
collaboration with Tony Lindgren <tony@atomide.com> and
Kevin Hilman <khilman@deeprootsystems.com>.
Boot-tested on 2430SDP (by Paul) and N810 (by Jarkko).
