-+ * Coldfire Cache Model
-+ *
-+ * The Coldfire processors use a Harvard architecture cache configured
-+ * as four-way set associative. The cache does not implement bus snooping
-+ * so cache coherency with other masters must be maintained in software.
-+ *
-+ * The cache is managed via the CPUSHL instruction in conjunction with
-+ * bits set in the CACR (cache control register). Currently the code
-+ * uses the CPUSHL enhancement which adds the ability to
-+ * invalidate/clear/push a cacheline by physical address. This feature
-+ * is designated in the Hardware Configuration Register [D1-CPES].
-+ *
-+ * CACR Bits:
-+ * DPI[28] cpushl invalidate disable for d-cache
-+ * IDPI[12] cpushl invalidate disable for i-cache
-+ * SPA[14] cpushl search by physical address
-+ * IVO[20] cpushl invalidate only
-+ *
-+ * Random Terminology:
-+ * * invalidate = reset the cache line's valid bit
-+ * * push = generate a line-sized store of the data if its contents are marked
-+ * as modifed (the modified flag is cleared after the store)
-+ * * clear = push + invalidate
