The module support for the thermal subsystem makes little sense:
- some subsystems relying on it are not modules, thus forcing the
framework to be compiled in
- it is compiled in for almost every configs, the remaining ones
are a few platforms where I don't see why we can not switch the thermal
to 'y'. The drivers can stay in tristate.
- platforms need the thermal to be ready as soon as possible at boot time
in order to mitigate
Usually the subsystems framework are compiled-in and the plugs are as
module.
Remove the module option. The removal of the module related dead code will
come after this patch gets in or is acked.

Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures. These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time. Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.
Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.

make fscrypt support for all fscrypt-capable filesystems be controlled

for all filesystems which support encryption, this commit removes
filesystem specific build config option (e.g. CONFIG_EXT4_FS_ENCRYPTION)

value affects all the filesystems making use of fscrypt.

If a small kernel is desired, WARN_ON can be disabled globally.
Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check.

generic_defconfig explicitly disables CONFIG_INPUT_MOUSEDEV,
CONFIG_INPUT_KEYBOARD & CONFIG_INPUT_MOUSE which results in warnings
when merging board config fragments if any of them require these
options. This is the case for the ranchu board, which means we've had
the following warning when configuring for generic platform targets
since commit f2d0b0d5c1 ("MIPS: ranchu: Add Ranchu as a new
generic-based board"):
$ make ARCH=mips 32r2el_defconfig

#
# configuration written to .config
#
Resolve this by removing mention of the CONFIG_INPUT_* Kconfig symbols
from generic_defconfig, allowing them to take their default values &
allowing board config fragments to enable them without warnings.
This may be problematic if CONFIG_ARCH_MIGHT_HAVE_PC_SERIO is ever
enabled for CONFIG_MIPS_GENERIC=y configurations, but for now that isn't
the case so we can worry about that if & when it happens.

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
||----MIPS CPU
|| | IRQs
||----Goldfish PIC------------(32)--------
|| | | | | | | | | |
||----Goldfish TTY------ | | | | | | | |

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
boot protocol DTB handover mode.

Signed-off-by: James Hogan <jhogan@kernel.org>
The generic MIPS system type allows building a board agnostic kernel and
should be the default starting point for users, so set it as the default
system type in Kconfig.
Since ip22 is no longer the default, update ip22_defconfig to select
CONFIG_SGI_IP22.

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.

Recent versions of udev and systemd require the kernel to be compiled
with CONFIG_DEVTMPFS in order to populate the /dev directory. Most MIPS
platforms have it enabled by default, so enable it for the Cavium Octeon
defconfig as well. This will assist with automated kernel boot testing.

Convert the MIPS SEAD-3 board support to be a generic board, supported
by generic kernels.
Because the SEAD-3 boot protocol was defined long ago and we don't want
to force a switch to the UHI protocol, SEAD-3 is added as a legacy board
which is detected by reading the REVISION register. This may technically
not be a valid memory read & future work will include attempting to
handle that gracefully. In practice since SEAD-3 is the only legacy
board supported by the generic kernel so far the read will only happen
on SEAD-3 boards, and even once Malta is converted the same REVISION
register exists there too. Other boards such as Boston, Ci20 & Ci40 will
use the UHI boot protocol & thus not run any of the legacy board detect
functions.

Introduce a "generic" platform, which aims to be board-agnostic by
making use of device trees passed by the boot protocol defined in the
MIPS UHI (Universal Hosting Interface) specification. Provision is made
for supporting boards which use a legacy boot protocol that can't be
changed, but adding support for such boards or any others is left to
followon patches.
Right now the built kernels expect to be loaded to 0x80100000, ie. in
kseg0. This is fine for the vast majority of MIPS platforms, but
nevertheless it would be good to remove this limitation in the future by
mapping the kernel via the TLB such that it can be loaded anywhere & map
itself appropriately.
Configuration is handled by dynamically generating configs using
scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc
makes use of it. This allows for variations upon the configuration, eg.
differing architecture revisions or subsets of driver support for
differing boards, to be handled without having a large number of
defconfig files.

Probe the UARTs on SEAD3 boards using device tree rather than platform
code, in order to reduce the amount of the latter. This requires that
CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig.
The SEAD3 DT shim code is extended to read bootloader environment
variables to determine the appropriate UART & mode for kernel console
output & set the stdout-path property of the chosen node accordingly.
In contrast to the old platform code, which appears to have only ever
set "console=ttyS0,38400n8r" with the code in console_config never
having an effect, this will honor the "yamontty" environment variable to
select between the 2 UARTs on the board and then check the "modetty0" or
"modetty1" variable as appropriate to determine the UART configuration.

Only one defconfig has a STACKPROTECTOR value. And it asks for
the strong variant, which isn't supported by older toolchains.
Due to the nature of MIPS having more platform specific code than say
x86, the allyesconfig and allmodconfig aren't as effective for build
coverage. So, in addition, I like to use a trivial script to walk all
the defconfigs and build each one.
However I will get false positives on unsupported stackprotector values
with an older toolchain like gcc-4.6.3. As in this instance I am just
using the compiler as a glorified syntax checker on a machine where I
build a bunch of other arch for the same reason, there is no real
motivation to get a newer toolchain for improved optimization etc.
Since there is only one of them, and there is nothing about these
settings that are board/platform specific, I propose we just eliminate
the existing instance and take the default.
