From c6dcb1010239e484a461178d3318b35ef44dbcf0 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Thu, 14 Aug 2014 10:37:22 -0500 Subject: ARM: dts: socfpga: memreserve first 4KB for future system use This patch adds a /memreserve/ section to reserve the first 4K for future use by the system. One possible use-case is trampoline code used to bring secondary cores online.
