  10. _armboot_start contains the value of TEXT_BASE (0xA07E0000); it seems
  11. TEXT_BASE and _armboot_start are both used for the same purpose in
  12. different parts of the (ARM) code.
  13. Furthermore, the startup code (cpu/<arm>/start.S) internally uses
  14. another variable (_TEXT_BASE) with the same content as _armboot_start.
  15. I agree that this mess should be cleaned up.
