Re: [PATCH] OMAP2xxx: move SRAM to fix boot hang

2008-10-10 Thread Tony Lindgren
* Paul Walmsley [EMAIL PROTECTED] [081010 02:23]:
 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 [EMAIL PROTECTED].  This patch is a
 collaboration with Tony Lindgren [EMAIL PROTECTED] and
 Kevin Hilman [EMAIL PROTECTED].
 
 Boot-tested on 2430SDP (by Paul) and N810 (by Jarkko).

Pushing.

Tony
