KEIL MDK external Flash templates (FLM)

Hi everyone.

i'm building some prototype devices based on a reference design from a client of mine. 

The reference design uses an AP8064 Audio SoC which has a Cortex M3 core.

The AP8064 does not have any on-board flash. The dev-kit and the reference design use a 25Q16CSIG flash chip, but it's difficult to get hold of here in the UK.

So on my prototypes I would like to use the SST25VF016B from Microchip (mainly because I already have hundreds of them in stock, its the same size and pin-out). 

So in order to do that I need to write a flash driver (.FLM) for the 25VF16.

But I cannot find any template or existing projects that target 25-Series flash chips.

Can anyone point me in the direction of a suitable starting point, or template for a 25-Series external flash chip to write the .FLM?
