ARM: simplify and fix linker script for TCM 2018-03-10T01:20:43+00:00 Nicolas Pitre nicolas.pitre@linaro.org 2018-03-09T02:12:04+00:00 b54290e51accea4f696f5dacef8e609d0ccbe54a 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. Signed-off-by: Nicolas Pitre <nico@linaro.org> Tested-by: Chris Brandt <Chris.Brandt@renesas.com>
