function PL011UARTCreate(Address:LongWord; const Name:String; IRQ,ClockRate:LongWord):PUARTDevice;

Description: Create and register a new PL011 UART device which can be accessed using the UART API

Address	The address of the PL011 registers
Name	The text description of this device which will show in the device list (Optional)
IRQ	The interrupt number for the PL011
ClockRate	The clock source frequency for the PL011
Return	Pointer to the new UART device or nil if the UART device could not be created

[Expand]

function PL011UARTDestroy(UART:PUARTDevice):LongWord;

Description: Close, deregister and destroy a PL011 UART device created by this driver

UART	The UART device to destroy
Return	ERROR_SUCCESS if completed or another error code on failure
