I apologize up front for my ignorance.

Q1: OK, so I gather the OCP system which until recently used to be in a separate OCP tree and was recently integrated into 2.6 is going away?

I had just started to do a 405 EP port of 2.6.11-rc4  based off of the bubinga config.

Q2: Assuming yes, to Q1, any advice on how I should proceed, continue on with an OCP port or wait for this new stuff?

Q3: How does one stay in the loop on this stuff? With only about 3 messages posted in this group and none in linuxppc-dev I am clearly in the wrong place. I feel like I missed the conversation. Where was it?

Best,
