    Hi,
       From the hardware manual of PPC 750 I know how to config L2 cache, such
       as cache size, cache frequency etc. But I want to know how to config
       L1 Cache? For example, L1 data & instruct cache of PPC 750
       are all 32KB, so how can I config it as 16KB each?

      Thanks.
