[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.
The bug with gcc 5 is not trivial, I'll do my best to explain it here.
Basically, there are two memory mappings of the code. One in "virtual memory",
and one in "load memory". The one in

[PATCH 0/4] Improve linker scripts
From: Sylvain Gault <sylvain.gault at gmail.com>
These patches basically remove unused linker scripts and port a change that was
made to an unused script.
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

But it is not important that is the linker patch.
Important is that the Syslinux project evolves further.
Thing I'm try to say:
moving is better then non-moving

[LLVMdev] [lld] Linker script findings.
...pt Primer
====================
As far as I can tell, ldscripts usually have suffix `.lds` and more rarely
`.ld`.
In order to provide some context for what follows, here is 90% of what you
need to know about linker scripts:
SECTIONS { /* (1) */
__text_start = .; /* (2) */
.text : { /* (3) */
*(.text); /* (4) */
*(.text.*);
}
__text_end = .;
__text_size = __text_end - __text_start; /* (...
