From f6e20fc6ca5a45316f94743d8b60dce4d9766bc8 Mon Sep 17 00:00:00 2001 From: wdenk Date: Sun, 8 Feb 2004 19:38:38 +0000 Subject: Patch by Anders Larsen, 09 Jan 2004: ARM memory layout fixes: the abort-stack is now set up in the correct RAM area, and the BSS is zeroed out as it should be. Furthermore, the magic variables 'armboot_end' and 'armboot_end_data' of the linker scripts are replaced by '__bss_start' and '_end', resp., which is a further step to eliminate unnecessary differences between the implementation of the CPU architectures. --- doc/README.ARM-memory-map | 10 ---------- 1 file changed, 10 deletions(-) (limited to 'doc/README.ARM-memory-map') diff --git a/doc/README.ARM-memory-map b/doc/README.ARM-memory-map index 8905a50..e2c4e16 100644 --- a/doc/README.ARM-memory-map +++ b/doc/README.ARM-memory-map @@ -15,13 +15,3 @@ different parts of the (ARM) code.
