E51 may configure the L1 and L2 caches. Once configured, no reconfiguration is possible after hardware reset is issued. L2 is 16-way set associative with write-back policy. The size 2 MB, from which 1 MB is utilized with the values provided here. That's a total of 8 ways. The rest of the L2 is left out for the bootloader usage. mpfs_enable_cache() first checks the bootloader usage doesn't overlap with the cache itself, thus providing a set of functional values.
