This replaces use of the no longer defined _armboot_start. --- diff --git a/doc/README.ARM-memory-map b/doc/README.ARM-memory-map deleted file mode 100644 index 1b120ac3e1..0000000000 --- a/doc/README.ARM-memory-map +++ /dev/null @@ -1,17 +0,0 @@ -Subject: Re: [PATCH][CFT] bring ARM memory layout in line with the documented behaviour -From: "Anders Larsen" -Date: Thu, 18 Sep 2003 14:15:21 +0200 -To: Wolfgang Denk - -... ->I still see references to _armboot_start, _armboot_end_data, and ->_armboot_end - which role do these play now?
