I have old development board Odroid N1 (RK3399), It has onboard PCIe
2 dual sata bridge.
I have tested this patch, but I am still getting following log on
Odroid N1 board.
Is their any more configuration needed for sata ports ?
Thanks for testing. I made a mistake that it should be bit 19, so
can you try using BIT(19)?
