This option supports all of the Octeon reference boards from Cavium
Networks. It builds a kernel that dynamically determines the Octeon
CPU type and supports all known board reference implementations.
Some of the supported boards are:
EBT3000
EBH3000
EBH3100
Thunder
Kodama
Hikari
Say Y here for most Octeon reference boards.

This option configures this kernel to be linked at a different
address and use the 2nd uart for output. This allows a kernel built
with this option to be run at the same time as one built without this
option.

help
Configure the Octeon hardware to automatically fix unaligned loads
and stores. Normally unaligned accesses are fixed using a kernel
exception handler. This option enables the hardware automatic fixups,
which requires only an extra 3 cycles. Disable this option if you
are running code that relies on address exceptions on unaligned
accesses.

local memory; the larger CVMSEG is, the smaller the cache is.
This selects the size of CVMSEG LM, which is in cache blocks. The

/*
* Spec
*
* memcpy copies len bytes from src to dst and sets v0 to dst.
* It assumes that
* - src and dst don't overlap
* - src is readable
* - dst is writable
* memcpy uses the standard calling convention
*
* __copy_user copies up to len bytes from src to dst and sets a2 (len) to
* the number of uncopied bytes due to an exception caused by a read or write.
* __copy_user assumes that src and dst don't overlap, and that the call is
* implementing one of the following:
* copy_to_user
* - src is readable (no exceptions when reading src)
* copy_from_user
* - dst is writable (no exceptions when writing dst)
* __copy_user uses a non-standard calling convention; see
* arch/mips/include/asm/uaccess.h
*
* When an exception happens on a load, the handler must
# ensure that all of the destination buffer is overwritten to prevent
* leaking information to user mode programs.
*/
/*
* Implementation
*/
/*
* The exception handler for loads requires that:
* 1- AT contain the address of the byte just past the end of the source
* of the copy,
* 2- src_entry <= src < AT, and
* 3- (dst - src) == (dst_entry - src_entry),
* The _entry suffix denotes values when __copy_user was called.
*
* (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
* (2) is met by incrementing src by the number of bytes copied
* (3) is met by not doing loads between a pair of increments of dst and src
*
* The exception handlers for stores adjust len (if necessary) and return.
* These handlers do not need to overwrite any data.
*
* For __rmemcpy and memmove an exception is always a kernel bug, therefore
* they're not protected.
