Nicolas Pitre b54290e51a ARM: simplify and fix linker script for TCM 
Let's put the TCM stuff in the __init section directly. No need for
a separately freed memory area.

Remove redundant linker sections, as well as comments that were more
confusing than no comments at all. Finally make it XIP compatible by
using LOAD_OFFSET in the section LMA specification.

Nicolas Pitre c3146c43db ARM: linker script: factor out TCM bits 
This is a plain move with identical results, and therefore
still broken in the XIP case.

Nicolas Pitre ab42fad009 ARM: linker script: factor out stuff for the DISCARD section 
Move common entries to vmlinux.lds.h and leave XIP and non-XIP entries
in their respective file. The ARM_NOMMU_KEEP() and ARM_NOMMU_DISCARD()
macros are added to be usable within the definition of ARM_DISCARD macro.

Nicolas Pitre 2f181e0ba8 ARM: linker script: factor out some common definitions between XIP and non-XIP 
Lots of duplications between vmlinux.lds.S and vmlinux-xip.lds.S.
This may lead to one file being updated but not the other. For example,
SOFTIRQENTRY_TEXT and HYPERVISOR_TEXT were missing from the XIP version.

This creates vmlinux.lds.h where a bunch of common defines are moved.
