Tips for adding support to latest uBoot when I have 1.1.1 level source (6 replies)

I have source code to an ancient uBoot version 1.1.1 I'd like to port this to the latest uboot, but I have no idea where to start and documentation on the uBoot site appears to be seriously out of date. I am an experienced C developer (over 20 years experience) and was a contributor to Linux back when m68k Macs were still a viable platform. I'd just like some pointers as I have not been able to decipher the structure of uboot (i.e. where to begin adding support).
