Hello,

So far I've been using an old 2.4 kernel I used for some Ocelot-G work, just to get past the TFTP-load stage. MY QUESTION IS: What would be the best kernel version for me to now start customizing for my board? Is 2.6 too bleeding-edge, 2.4 too moldy, or what? Dealing with the MV64341 will be most of the effort, of course.
I have recently hacked a 2.6 Linux-MIPS kernel for a custom RM9000 / MV64340 board, and it worked pretty well.
For the MV64340 UART, you can find a driver in the Bitkeeper PowerPC tree available at Montavista. Otherwise, I have written an other driver, much smaller, but maybe less functionnal than the one available from Montavista.
The Ocelot boards seem well supported, but there looks to be a lot of code that would have to change (different system controller, different memory map--though I'm flexible--a lot of assumptions about the goodies available on-board, etc.). This is the first time I'll be porting the kernel, so it might be more productive for me to start from a minimalist configuration and add-in what I need. Enough code to set up the memory configuration would be a big help.
Have a look at Linux-MIPS Wiki (http://www.linux-mips.org) it contains an updated version of the MIPS porting guide from Jun Sun. It's a very good starting point in my opinion.
