From 86ed40bd6fe511d26bb8f3fa65a84cb65c235366 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 27 Dec 2008 00:35:12 -0800 Subject: [PATCH] sparc: unify sections.h While doing this use standard names for start/end so we could use definitions straight from asm-generic for all the typical symbols. This also allowed us to drop the use of PROVIDE in the linker script so sprc is less non-standard on this area. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
