[PATCH 0/2] Fixes for gcc 5
From: Sylvain Gault <sylvain.gault at gmail.com>
TL;DR: The section aligment in linker scripts messed-up the memory mapping
needed for the compression / decompression to work.

[PATCH 0/4] Improve linker scripts
From: Sylvain Gault <sylvain.gault at gmail.com>

Those are to be applied on top of the gcc 5 bug fixes as they would conflict
otherwise.
Sylvain Gault (4):
diag/mbr: fix dependency to linker script
Remove unused linker scripts
core: Make symbols defined in linker script HIDDEN
