[PATCH 3.2 125/149] m68k: use non-MMU linker script for ColdFire MMU builds

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.2.52-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Ungerer <gerg@xxxxxxxxxxx>

commit ed865e31a8273be200db9ddcdb6b844e48777abd upstream.

Use the non-MMU linker script for ColdFire builds when we are building
for MMU enabled. The image layout is correct for loading on existing
ColdFire dev boards. The only addition required to the current non-MMU
linker script is to add support for the fixup section.
