    8787* June 15: This week I tried to run JTAG. And came to know that there is already some [ problem] of JTAG with raspberry pi. So I was not able to use JTAG for debugging purpose. I should have done some more research before buying the JTAG. That could have saved a lot of my time. So, now the only option left for me to debug the problem is putting printf statements in all the code which I added. Using this approach I have narrowed down the problem till some extent. The program hangs in one of the ofw bus status call. While adding the code from freebsd I had to add many files due to compilation errors. Now my plan is to add all the file one by one, analyse all the errors causing it and debug.
    8888* June 24: I have successfully ported the bcm283x_dwcotg driver for the Raspberry Pi. I ran init0 test on my Raspberry Pi Model 1/B+. Driver loaded successfully without hanging. Changes can be seen [ here]. Apart from that I am getting error in mailbox functions (failed to set power state, err=-2). As far as I know Pavel and Mudit are looking into this problem. I will start working with them for the same. I can not move to next part before solving this. Also, I gave the work done till now for code review.
     89* June 29: Mailbox Error resolved. bcm283x_dwcotg ported successfully.Currently I am trying to port usb_ethernet driver. Resolving errors while compiling.
     90* July 13: I have added files for usb_ethernet and bcm283x_dwcotg till now. I am stuck at the point where I have to connect both of them. I have started the [ email thread] regarding this issue. Alan and Chris are looking into the problem with me.
