config CAVIUM_OCTEON_2ND_KERNEL
bool "Build the kernel to be used as a 2nd kernel on the same chip"
depends on CAVIUM_OCTEON_SPECIFIC_OPTIONS
default "n"
help
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.
config CAVIUM_OCTEON_HW_FIX_UNALIGNED
bool "Enable hardware fixups of unaligned loads and stores"
depends on CAVIUM_OCTEON_SPECIFIC_OPTIONS
default "y"
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.

CVMSEG LM is a segment that accesses portions of the dcache as a
local memory; the larger CVMSEG is, the smaller the cache is.
This selects the size of CVMSEG LM, which is in cache blocks. The
legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is
between zero and 6192 bytes).
