_armboot_start contains the value of TEXT_BASE (0xA07E0000); it seems
|
|
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.
|
|
|
|
_armboot_end_data is the end address of the initialized data section,
|
|
and is only used in one place (board/logodl/flash.c - the reference in
|
|
lib_arm/board.c is purely informational).
|
|
|
|
_armboot_end is the end address of the BSS and is used to determine
|
|
the address of the VFD buffer.
|
|
|
|
Eliminating those should be doable, and at least the patch already
|
|
eliminates _armboot_real_end.
