12*4882a593Smuzhiyun_armboot_start contains the value of CONFIG_SYS_TEXT_BASE (0xA07E0000); it seems
13*4882a593SmuzhiyunCONFIG_SYS_TEXT_BASE and _armboot_start are both used for the same purpose in
14*4882a593Smuzhiyundifferent parts of the (ARM) code.
15*4882a593SmuzhiyunFurthermore, the startup code (cpu/<arm>/start.S) internally uses
16*4882a593Smuzhiyunanother variable (_TEXT_BASE) with the same content as _armboot_start.
17*4882a593SmuzhiyunI agree that this mess should be cleaned up.
