before i submit a patch, i'll ask permission first -- is it worth submitting patches to delete what appear to be totally obsolete README files? i just stumbled over doc/README.ARM-memory-map, dated Sep 2003, which reads in part:
"_armboot_start contains the value of CONFIG_SYS_TEXT_BASE (0xA07E0000); it seems CONFIG_SYS_TEXT_BASE and _armboot_start are both used for the same purpose in different parts of the (ARM) code. Furthermore, the startup code (cpu/<arm>/start.S) internally uses another variable (_TEXT_BASE) with the same content as _armboot_start. I agree that this mess should be cleaned up."
i checked -- there are no remaining references to _armboot_start, and there's this from 2011:
commit 297f18ac0fbeef30ba1c17fe131ca75f09a6e7cf Author: Greg Ungerer greg.ungerer@opengear.com Date: Fri Sep 9 22:23:34 2011 +1000
CM4000: fix broken flash base for OpenGear boards
Use _bss_start_ofs as the size of the boot loader code+data that we want to protect in the flash. This replaces use of the no longer defined _armboot_start. ... etc etc ...
under the circumstances, does that file have any current informational value? i'm pretty sure i've noticed a couple others that seem way out of date.
