From b1e2c5519a06f9a5841a7a434bf4da4d393f8df5 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 3 Nov 2009 06:11:31 -0500 Subject: Blackfin: move section length calculation to linker script The length of the sections is fixed at link time, so let the linker do the calculation rather than doing it ourselves at runtime.
