Welcome! I really appreciate that step. > One of the first things I came across is that we need some significant > changes to some of the MIPS specific libraries and start-up code.

We should in a first step split the current arch/mips/cpu/ into arch/mips/cpu/au1x00/ and arch/mips/cpu/incaip/; common stuff should go to arch/mips/lib/. In the second step, you could add a arch/mips/cpu/octeon/ directory. > These changes would be global across the Octeon and not board specific.

Fine. > Also, what would be a good stable starting version to work from? Top of tree. Your code will be picked up by Shinya Kuribayashi and then pulled from his u-boot-mips repository into mainline. If it should turn out that you generate a lot of commits for a longer time (i. e. more than just an initial pile) we can as well give you a separate u-boot-octeon repository. Just let me know when you feel that would help you.
