| Wolfgang Denk | 0708bc6 | 2010-10-07 21:51:12 +0200 | [diff] [blame] | 12 | _armboot_start contains the value of CONFIG_SYS_TEXT_BASE (0xA07E0000); it seems |
| 13 | CONFIG_SYS_TEXT_BASE and _armboot_start are both used for the same purpose in |
| wdenk | c0aa5c5 | 2003-12-06 19:49:23 +0000 | [diff] [blame] | 14 | different parts of the (ARM) code. |
| 15 | Furthermore, the startup code (cpu/<arm>/start.S) internally uses |
| 16 | another variable (_TEXT_BASE) with the same content as _armboot_start. |
| 17 | I agree that this mess should be cleaned up. |
