V5.x porting guide or prototypical example?

[groups at chichak.ca]

\Good day,

A while back I put together a BSP for STM32F7 based on the STM32F407 BSP for an early version of RTEMS 5.

Now that RTEMS 5 became 5.0, the BSP structure has moved around quite a bit and I need to redo my BSP.

Is there a porting guide for 5.0 yet, or is there a shining example of a BSP that I should emulate?

Thanks,

Andrei
