cpu_specs[] is full of #ifdefs depending on the different types of CPU. CPUs are mutually exclusive, it is therefore possible to split cpu_specs[] into smaller more readable pieces. Create cpu_specs_XXX.h that will each be dedicated on one of the following mutually exclusive families: - 40x - 44x - 47x - 8xx - e500 - book3s/32 - book3s/64 In book3s/32, the block for 603 has been moved in front in order to not have two 604 blocks.
