12*14d0a02aSWolfgang Denk_armboot_start contains the value of CONFIG_SYS_TEXT_BASE (0xA07E0000); it seems
13*14d0a02aSWolfgang DenkCONFIG_SYS_TEXT_BASE and _armboot_start are both used for the same purpose in
14a8c7c708Swdenkdifferent parts of the (ARM) code.
15a8c7c708SwdenkFurthermore, the startup code (cpu/<arm>/start.S) internally uses
16a8c7c708Swdenkanother variable (_TEXT_BASE) with the same content as _armboot_start.
17a8c7c708SwdenkI agree that this mess should be cleaned up.
