From cd8dc7ae41f2b2e6392e32c8471589a8ca5fa705 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Sat, 15 Jun 2013 09:01:49 +0900 Subject: [PATCH] ARM: SAMSUNG: Introduce SAMSUNG_ATAGS Kconfig entry This patch adds a Kconfig entry that enables compilation of legacy support code required for Samsung platforms that require ATAGS based boot. This allows to bypass compilation of this code when platforms without ATAGS support are selected.
