Bhupesh Sharma	465663e9f1	ArmPlatformPkg/TZASC: Allow specifying subregions to be disabled ARM TZASC-380 IP provides a mechanism to split memory regions being protected via it into eight equal-sized sub-regions. A bit-setting allows the corresponding subregion to be disabled. Several NXP/FSL SoCs support the TZASC-380 IP block and allow the DDR connected via the TZASC to be partitioned into regions having different security settings and also allow subregions to be disabled. This patch enables this support and can be used for SoCs which support such a partition of DDR regions.

ArmPlatformPkg/TZASC: Allow specifying subregions to be disabled

ARM TZASC-380 IP provides a mechanism to split memory regions being
protected via it into eight equal-sized sub-regions. A bit-setting
allows the corresponding subregion to be disabled.

Several NXP/FSL SoCs support the TZASC-380 IP block and allow
the DDR connected via the TZASC to be partitioned into regions
having different security settings and also allow subregions
to be disabled.

This patch enables this support and can be used for SoCs which
support such a partition of DDR regions.

Details of the 'subregion_disable' register can be viewed here:

ArmPlatformPkg: Moved 'ArmTrustZoneLib' from ArmPkg/Library to ArmPlatformPkg/Drivers

This library is really the driver for the ARM Trustzone controllers (TZPC and TZASC).
