EMAC is TSE or Designware ?

Hello,

I am a bit confused with emac.

I see that several git bsp for altera contains altera_tse.c, but on checking arria TRM it says that it use desginware IP in emac.

I find the same in cyclone V TRM.

So are these FPGAs (arria and cyclon) use tse or designware in EMAC ?

Where can I find baremetal driver for the HPS ?

Thank you!
