Creating UART layered device

Subject: [ECOS] Creating UART layered device

Hello,

I want to write a driver for the EXAR XR16M698 8 channel UART, which is based on the 16C550 registers.
And then use it for multi-targets.

What is the best way to perform this ?

I have found the generic 16x5x driver in packages/devs/serial/generic.

Should I create a layered device on top of 16x5x package for the exar component and then create an inline for my targets ?

How could I write layered device, I haven't found any example.

Regards,
Nicolas FLAVEN
