+------------------------------
+1. Create the new platform directory under ArmPlatformPkg
+
+2. Create its DSC and FDF files into this new directory. These files can be copied from ArmVExpress-CTA9x4.dsc and ArmVExpress-CTA9x4.fdf; and adapted following the requirement of your platform.
+
+3. Set up the PCDs required by ArmPlatformPkg in your FDF or DSC files
+
+PCD Description
+gArmTokenSpaceGuid.PcdSecureFdBaseAddress : Base address of your Secure Firmware
+gArmTokenSpaceGuid.PcdSecureFdSize : Size in byte of your Secure Firmware gEmbeddedTokenSpaceGuid.
+PcdEmbeddedFdBaseAddress : Base Address of your Non-Secure Firmware gEmbeddedTokenSpaceGuid.
+PcdEmbeddedFdSize : Size in bytes of your Non-Secure Firmware
+gArmTokenSpaceGuid.PcdL2x0ControllerBase : Base Address of your L2x0 controller
+gArmTokenSpaceGuid.PcdGicDistributorBase : Base address of the Distributor of your General Interrupt Controller gArmTokenSpaceGuid.
+PcdGicInterruptInterfaceBase : Base address of the Interface of your General Interrupt Controller gArmVExpressTokenSpaceGuid.
+PcdCPUCoresSecStackBase : Top of Secure Stack for Secure World gArmVExpressTokenSpaceGuid.
+PcdCPUCoreSecStackSize : Size of the stack for each of the 4 CPU cores gArmVExpressTokenSpaceGuid.
+PcdCPUCoresSecMonStackBase : Top of Stack for Monitor World gArmVExpressTokenSpaceGuid.
+PcdCPUCoreSecMonStackSize : Size of the stack for each of the 4 CPU cores gArmVExpressTokenSpaceGuid.
+PcdCPUCoresNonSecStackBase : Top of SEC Stack for Normal World gArmVExpressTokenSpaceGuid.
+PcdCPUCoresNonSecStackSize : Size of the stack for each of the 4 CPU Cores gArmVExpressTokenSpaceGuid.
+PcdPeiServicePtrAddr : Cached value of PeiServicesTable
+
+4. Implement 'ArmPlatformLib' for your platform following the interface defined by ArmPlatformPkg\Include\Library\ArmPlatformLib.h.
+
+Functions to implement:
+
+VOID ArmPlatformIsMemoryInitialized(VOID);
+VOID ArmPlatformInitializeBootMemory(VOID);
+VOID ArmPlatformInitializeSystemMemory(VOID);
+VOID ArmPlatformBootRemapping(VOID);
+UINTN ArmPlatformTrustzoneSupported(VOID);
+VOID ArmPlatformTrustzoneInit(VOID);
+VOID ArmPlatformGetPeiMemory (
+ OUT UINTN* PeiMemoryBase,
+ OUT UINTN* PeiMemorySize);
+VOID ArmPlatformGetVirtualMemoryMap (
+ OUT ARM_MEMORY_REGION_DESCRIPTOR** VirtualMemoryMap);
+VOID ArmPlatformGetEfiMemoryMap (
