// Examples of what goes in here include:

//

// - General-purpose I/O allocation such as 

//	 #define KtVariantGpio32KHzClkOut		KHtGpioPort1

//	 #define KtVariantGpioRClkOut			KHtGpioPort0

//

//	 #define KmVariantPinDirectionIn Sleep	0

//

// - Memory constants (type, geometry, wait states, etc) such as:

//	 #define KwVariantRom0Type				TTemplate::ERomTypeBurst4Rom

//	 #define KwVariantRom0Width				TTemplate::ERomWidth32

//	 const TUint KwVariantRom0WaitNs		= 150;

//	 const TUint KwVariantRom0PageNs		= 30;

//	 const TUint KwVariantRom0RecoverNs		= 55;

//

// - Specific Peripherals (Keyboard, LCD, CODECS, Serial Ports) such as 

//	 const TUint KwVariantKeyColLshift		= 7;

//	 #define KwVariantLcdBpp				TTemplate::ELcd8BitsPerPixel

//   const TUint KwVariantLcdMaxColors		= 4096;

//   const TUint KwVariantCodecMaxVolume	= 0;

//

// - Off-chip hardware control blocks (addresses, register make-up)

//

// - Interrupts (second-level Interrupt controller base address, register make-up):

//   (EXAMPLE ONLY:)
