Ethernet in RGMII mode on LS1021A

Hi,

I am new to LS1021A and this family. I am going to write driver for Ethernet in RGMII mode.

Being a newbie and datasheet is vast, is there any application note or something which will give me a path for Ethernet driver implementation?

In this case it is reasonable to refer to the U-Boot source code provided in the Linux SDK available at:

Is there any Application note available... Instead of referring source code?

There is no such application note.

Basic initialization steps are provided in the QorIQ LS1021A Reference Manual, Table 20-52. RGMII mode register initialization steps.
