  Move most of the timer interrupt related PPC code to ppc_lib/interrupts.c

* Patch by Anders Larsen, 17 Sep 2003:
  Bring ARM memory layout in sync with the documentation:
  stack and malloc-heap are now located _below_ the U-Boot code

+
+_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.
