Basically the most intrusive part is the addition of two new RGMII Internal Delay modes; one for TX delay only, and the other for RX delay only (i.e, not both at the same time). Please review, and since this affects both netdev and powerpc trees, one maintainer should ack them for the other to push upstream (i.e, Kumar acks them, and Leo picks them up to go through netdev or the other way around; either way is fine with me). I'm hoping they're trivial enough to go in 2.6.24. Depending on how the review goes, a follow-on patch to u-boot will be sent out that fixes up the phy-connection-type in the device tree (from "rgmii-id" to "rgmii-rxid" iff on mpc8360rev2.1). Thanks, Kim mpc8360 rev 2.1 erratum #2: ----------- Recommended AC timings for chip 8360Rev2.1 UCC ETH RGMII when working with Rev Pilot MDS for proper RGMII operation: IMMR_BASE + 0x14A8[4:5] = 11 (clk delay for UCC 2) IMMR_BASE + 0x14A8[18:19] = 11 (clk delay for UCC 1) IMMR_BASE + 0x14AC[20:27] = 10101010 (data delay for both UCC's) The Phy (Marvell 88e1111) should be configured NOT to work with RGMII delay for TxD.
