[U-Boot] [PATCH] doc: delete long-obsolete README.ARM-memory-map

[Robert P. J. Day]

As far back as 2011, "_armboot_start" was being described as "no
longer defined":

   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.

->I still see  references  to  _armboot_start,  _armboot_end_data,  and
->_armboot_end - which role do these play now? Can we get rid of them?
->
->How are they (should they be) set in your memory map above?
-
-_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.
