I have made a trivial little patch (and a few files..) to define a "minimally configured" 405[gp] board. Its basically a 405 with no KB, RTC, PCI, et.al. The idea being that if you define this submodel of CONFIG_4xx then you write loadable modules on your own to handle peripherals; this being just enough in the kernel to get you to net- or flash-boot. Its like a "WALNUT" but without any peripheral bank setup, RTC or KB assumptions.. you get the idea. In our case we bolt on lots of silly junk to the expansion banks and do DMA... but all inside of custom little drivers that set those banks up. Might we be able to limit the proliferation of submodel in the PPC 4xx world with the addition of my proposed MINIMAL405 submodel and then let vendors write drivers instead of kernels? For any who care, have a peek at http://www.toimi.com/linuxppc for the .patch file and a .tar file of needed additional platform files.
