This is a series of patches that are a work-in-progress towards a new DDR initialization for the Freescale 8{3,5,6}xxx devices that have a common DDR controller.
(Sorry for the previous "no subject" message - hit the "send" too soon...) Kumar, Does this RFC also include support for identifying and initializing more than one DDR module? David.

I'm not sure I follow exactly what you are asking? Do you mean using different DDR modules on different chip selects of the same controller? or something else?

Kumar - the current SPD DDR code assumes a single DIMM with a single fixed I2C address. Does your RFC add support for more than one DIMM on the same controller?
Yes, it should.

John - thanks, just wanted to elaborate to receive Kumar's ack.

Yes it should. The 8641 HPCN has 2-dimm slots per controller and both dimm slots are supported.
