Granule Protection Tables (GPT) library support is enabled only when ENABLE_RMM is set (previously this build option was ENABLE_RME). Since RME related support is now enabled using feature detection option ENABLE_FEAT_RME, this patch moves GPT support under ENABLE_FEAT_RME. This change brings in below benefits: - single TF-A build that works for RME and non-RME systems, when build with ENABLE_FEAT_RME=2 (FEAT_STATE_CHECK) - RMM loading is optional on RME systems - SiP calls that leverages RME features to change the PAS of a memory range from non-secure to secure is supported without need to enable Realm PAS or RMM. - FIRME Granule Management Interface (GMI) ABIs that handles FEAT_RME_GPC2/FEAT_RME_GDI can be enabled without need to enable RMM Signed-off-by: Arunachalam Ganapathy <arunachalam.ganapathy@arm.com> Change-Id: I88d9d4e0491af2b4ae0307c018f2d4a71ee6693f
