From ea2db495f92ad2cf3301623e60cb95b4062bc484 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 31 Mar 2010 21:59:21 +0200 Subject: ssb: Look for SPROM at different offset on higher rev CC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Our offset handling becomes even a little more hackish now. For some reason I do not understand all offsets as inrelative. It assumes base offset is 0x1000 but it will work for now as we make offsets relative anyway by removing base 0x1000. Should be cleaner however. Signed-off-by: Rafał Miłecki Signed-off-by: John W.
