From 5e837387aa7260518cf43f53b66ee917d8660802 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 12 Oct 2009 02:39:18 -0700 Subject: simplify XScale debug handler installation Load the XScale debug handler from the read-only data section instead of from a separate file that can get lost or garbaged. This eliminates installation and versioning issues, and also speeds up reset handling a bit. Plus some minor bits of cleanup related to loading that handler: comments about just what this handler does, and check fault codes while writing it into the mini-icache. The only behavioral changes should be cleaner failure modes after errors during handler loading, and being a bit faster. NOTE: presumes GNU assembly syntax, with ".incbin"; and ELF, because of the syntax of the ".size" directive.
