The watchdog is an useful piece of hardware, so there's no reason not to
enable it.
Besides, this is important for restart to work after the change in the
next commit.
This commit enables the Kconfig option in the qi_lb60 defconfig.

Enable the crc32-mips module on MIPS generic r6 configs, where the
required MIPS r6 CRC instructions may be available.
As well as allowing the CRC instructions to be utilised, this should
also ensure the module gets some build coverage.

Provide amendments to the MIPS generic platform framework so that
the new generic-based board Ranchu can be chosen to be built.
The Ranchu board is intended to be used by Android emulator. The name
"Ranchu" originates from Android development community. "Goldfish" and
"Ranchu" are terms used for two generations of virtual boards used by
Android emulator. The name "Ranchu" is a newer one among the two, and
this patch deals with Ranchu. However, for historical reasons, some
devices/drivers still contain the name "Goldfish".
MIPS Ranchu machine includes a number of Goldfish devices. The support
for Virtio devices is also included. Ranchu board supports up to 16
Virtio devices which can be attached using Virtio MMIO Bus. This is
summarized in the following picture:
ABUS

Device Tree is created on the QEMU side based on the information about
devices IO map and IRQ numbers. Kernel will load this DTB using UHI

On systems that support MT ASE multithreading (ie. VPEs) we are very
likely to want to include that support as default. Rather than setting
it in various defconfigs, simply make CONFIG_MIPS_MT_SMP default y such
that systems which select CONFIG_SYS_SUPPORTS_MULTITHREADING get it by
default.
As well as allowing us to remove the selection of CONFIG_MIPS_MT_SMP
from various defconfigs, this also allows the generated generic
defconfigs which derive from generic_defconfig to automatically gain
support for MT ASE SMP when building for a suitable (pre-MIPSr6) ISA.
For malta_kvm_guest_defconfig CONFIG_MIPS_MT_SMP is explicitly disabled
since enabling SMP implicitly disables CONFIG_KVM_GUEST, which depends
on CONFIG_BROKEN_ON_SMP.

The NI 169445 board uses a little endian MIPS32r2 CPU, and therefore
including board support in kernels that are unable to run on such a CPU
is pointless.
Specify requirements in the board config fragment that cause the NI
169445 board support to only be included in generic kernels that target
little endian MIPS32r2 CPUs.
For example, NI 169445 support will be included when configuring using
32r2el_defconfig but not when using 64r6_defconfig.

The MIPS SEAD-3 development board has only ever been used with 32 bit
CPUs, so including support for it in 64 bit kernels is wasteful since
those kernels will never run on a SEAD-3.
Specify a requirement in the SEAD-3 board config fragment that ensures
the board support is only included in 32 bit kernels, by checking that
CONFIG_32BIT=y.

Add support for the MIPS Boston development board to generic kernels,
which essentially amounts to:
- Adding the device tree source for the MIPS Boston board.
- Adding a Kconfig fragment which enables the appropriate drivers for
the MIPS Boston board.
With these changes in place generic kernels will support the board by
default, and kernels with only the drivers needed for Boston enabled can
be configured by setting BOARDS=boston during configuration. For
example:
$ make ARCH=mips 64r6el_defconfig BOARDS=boston

The generic_defconfig is used for platforms like SEAD3 which do not
usually have fixed storage available, therefore NFS is the preferred
location of the RFS.
When the upstream kernel defconfig is built & tested on platforms such
as SEAD3 this leads to essentially false failures when the RFS fails to
mount.
There is little harm in having this feature enabled by default, so
enable it in the defconfig. Kernel autoconfiguration & DHCP must also be
selected to allow RFS on NFS.

One of the last remaining failures in kernelci.org is for a gcc bug:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190
This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot
reproduce the problem here. However, it is clear that ip27_defconfig
does not actually need this driver as the platform has only PCI-X but
not PCIe, and the qlge adapter in turn is PCIe-only.
The driver was originally enabled in 2010 along with lots of other
drivers.
