powerpc/cputable: Split cpu_specs[] out of cputable.h 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.

powerpc/cputable: Add missing PPC_FEATURE_BOOKE on PPC64 Book-E Commit e320a76db4b0 ("powerpc/cputable: Split cpu_specs[] out of cputable.h") moved the cpu_specs to separate header files. Previously PPC_FEATURE_BOOKE was enabled by CONFIG_PPC_BOOK3E_64. The definition in cpu_specs_e500mc.h for PPC64 no longer enables PPC_FEATURE_BOOKE. This breaks user space reading the ELF hwcaps and expect PPC_FEATURE_BOOKE. Debugging an application with gdb is no longer working on e5500/e6500 because the 64-bit detection relies on PPC_FEATURE_BOOKE for Book-E.
