If not, then why should the 8309 get its own reinvented SICR_1/2_ etc.? Just looking for some consistency here... Kim

Plus it should be the last one of the series so there won't be much use in the future either. So unless you think that's absolutely necessary, I'd submit a v2 without this. Thanks again, Gerlando

This processor, though very similar to other members of the PowerQUICC II Pro family (namely 8308, 8360 and 832x), provides yet another feature set than any supported sibling. So we add a bunch of new #ifdefs (or complicate the existing ones) to arch/powerpc/cpu/mpc83xx/speed.c. Perhaps it would be worth to refactor the whole file so to first identify the featureset of the given CPU, and enclose each block within #ifdef CONFIG_MPC83XX_FEAT_XXXX for instance: - CONFIG_MPC83XX_FEAT_USBDR - CONFIG_MPC83XX_FEAT_QE - CONFIG_MPC83XX_FEAT_DDRSEC ...etc...
