Porting for embedded linux like raspberry and beaglebone

I wanted to make liberia compatible with linux embedded. I think it would only change the library of the I2C, SPI, UART or series and the library (time) for time management.

Do you give me permission to carry out the porting? What do you think? Could you give me guidance on where to start?

Thank you!

Note: What is the maximum output frequency of the AHRS?
