624 This option supports all of the Octeon reference boards from Cavium
625 Networks. It builds a kernel that dynamically determines the Octeon
626 CPU type and supports all known board reference implementations.
627 Some of the supported boards are:
628 EBT3000
629 EBH3000
630 EBH3100
631 Thunder
632 Kodama
633 Hikari

24/*
25 * Spec
26 *
27 * memcpy copies len bytes from src to dst and sets v0 to dst.
28 * It assumes that
29 * - src and dst don't overlap
30 * - src is readable
31 * - dst is writable
32 * memcpy uses the standard calling convention
33 *
34 * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
35 * the number of uncopied bytes due to an exception caused by a read or write.
36 * __copy_user assumes that src and dst don't overlap, and that the call is
37 * implementing one of the following:
38 * copy_to_user
39 * - src is readable (no exceptions when reading src)
40 * copy_from_user
41 * - dst is writable (no exceptions when writing dst)
42 * __copy_user uses a non-standard calling convention; see
43 * arch/mips/include/asm/uaccess.h
44 *
45 * When an exception happens on a load, the handler must
46 # ensure that all of the destination buffer is overwritten to prevent
47 * leaking information to user mode programs.
48 */
49
50/*
51 * Implementation
52 */
53
54/*
55 * The exception handler for loads requires that:
56 * 1- AT contain the address of the byte just past the end of the source
57 * of the copy,
58 * 2- src_entry <= src < AT, and
59 * 3- (dst - src) == (dst_entry - src_entry),
60 * The _entry suffix denotes values when __copy_user was called.
61 *
62 * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
63 * (2) is met by incrementing src by the number of bytes copied
64 * (3) is met by not doing loads between a pair of increments of dst and src
65 *
66 * The exception handlers for stores adjust len (if necessary) and return.
67 * These handlers do not need to overwrite any data.
68 *
69 * For __rmemcpy and memmove an exception is always a kernel bug, therefore
70 * they're not protected.

48 * to determine what model of chip the software is running on. Models
49 * ending in 'XX' match multiple models (families), while specific
50 * models match only that model. If a pass (revision) is specified,
51 * then only that revision will be matched. Care should be taken when
52 * checking for both specific models and families that the specific
53 * models are checked for first. While these defines are similar to
54 * the processor ID, they are not intended to be used by anything
55 * other that the OCTEON_IS_MODEL framework, and the values are
56 * subject to change at anytime without notice.
57 *
58 * NOTE: only the OCTEON_IS_MODEL() macro/function and the OCTEON_CN*
59 * macros should be used outside of this file. All other macros are
