[openwrt.git] / target / linux / coldfire / patches / 046-mcfv4e_kern_to_phys.patch
1 From 13fc0abf4b5da6f18dea15fd31697655615a79fc Mon Sep 17 00:00:00 2001
2 From: Kurt Mahan <kmahan@freescale.com>
3 Date: Wed, 12 Mar 2008 15:39:03 -0600
4 Subject: [PATCH] Move kernel to physical sdram base address.
5
6 Work based on the patches from Systec GMBH. Also DMA support,
7 uBoot integration, FEC fixes, and assorted cleanups.
8
9 Uber patch needs to be split up.

932 - * Coldfire Cache Model
933 - *
934 - * The Coldfire processors use a Harvard architecture cache configured
935 - * as four-way set associative. The cache does not implement bus snooping
936 - * so cache coherency with other masters must be maintained in software.
937 - *
938 - * The cache is managed via the CPUSHL instruction in conjunction with
939 - * bits set in the CACR (cache control register). Currently the code
940 - * uses the CPUSHL enhancement which adds the ability to
941 - * invalidate/clear/push a cacheline by physical address. This feature
942 - * is designated in the Hardware Configuration Register [D1-CPES].
943 - *
944 - * CACR Bits:
945 - * DPI[28] cpushl invalidate disable for d-cache
946 - * IDPI[12] cpushl invalidate disable for i-cache
947 - * SPA[14] cpushl search by physical address
948 - * IVO[20] cpushl invalidate only
949 - *
950 - * Random Terminology:
951 - * * invalidate = reset the cache line's valid bit
952 - * * push = generate a line-sized store of the data if its contents are marked
953 - * as modifed (the modified flag is cleared after the store)
954 - * * clear = push + invalidate
