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.

  - Adding a Kconfig fragment which enables the appropriate drivers for

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: 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.

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.
