From a50a5830d5a4df53d04f14d06634faed018fa206 Mon Sep 17 00:00:00 2001 From: Chandni Cherukuri Date: Tue, 14 Aug 2018 15:25:34 +0530 Subject: [PATCH] plat/arm/sgi: remove unused code On SGI platforms, the interconnect is setup by the SCP and so the existing unused interconnect setup in sgi575 platform code can be removed. As a result of this, sgi_plat_config.c and sgi_bl1_setup.c files can be removed as these files are now empty or can be substainated by the existing weak functions.
