The support was for this was added to mainline over 12 years ago, in
v2.6.26 [4e8aae89a35d] just around the ppc --> powerpc migration.
I believe the board was introduced shortly after the sbc8548 board,
making it roughly a 14 year old platform - with the CPU speed and
memory size typical for that era.
I haven't had one of these boards for several years, and availability
was discontinued several years before that.
Given that, there is no point in adding a burden to testing coverage
that builds all possible defconfigs, so it makes sense to remove it.
Of course it will remain in the git history forever, for anyone who
happens to find a functional board and wants to tinker with it.

Pull Kconfig file consolidation from Masahiro Yamada:
"Consolidation of bus (PCI, PCMCIA, EISA, RapidIO) config entries by
Christoph Hellwig.
Currently, every architecture that wants to provide common peripheral
busses needs to add some boilerplate code and include the right
Kconfig files. This series instead just selects the presence (when
needed) and then handles everything in the bus-specific Kconfig file
under drivers/"
* tag 'kconfig-v4.21-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
pcmcia: remove per-arch PCMCIA config entry
eisa: consolidate EISA Kconfig entry in drivers/eisa
rapidio: consolidate RAPIDIO config entry in drivers/rapidio

There is no good reason to duplicate the RAPIDIO menu in various
architectures. Instead provide a selectable HAVE_RAPIDIO symbol
that indicates native availability of RAPIDIO support and the handle
the rest in drivers/pci. This also means we now provide support
for PCI(e) to Rapidio bridges for every architecture instead of a
limited subset.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

- A two e600 cores Freescale MPC8641D CPU
- 2 GB of DDR2 onboard memory
- Four Gigabit Ethernets
- Five 16550 compatible UARTs
- One USB 2.0 port
- Two PCI/PCI eXpress Mezzanine Card (PMC/XMC) Slots
- A DS1375 Real Time Clock (RTC)
- 512 KB of Non-Volatile Memory (NVRAM)
- Two 64 KB EEPROMs
- 128 MB NOR and 4/8 GB NAND Flash
This patch is based on linux-4.7-rc1 and has been only boot tested.
Limitations:
This patch covers only models 171 and 173
No plans to support CPLD timers
Know issues:
All four PHYs work in polling mode
Configuration is missing for:
PCI IDSEL and PCI Interrupt definition
Support is missing for:
Cache and memory controllers (which are very similar to the 85xx ones
but right now I don't know if we can re-use their support)

This replaces:
- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
now be selected directly.
- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.
When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
the platforms, because this option is per-platform and not per-driver.

This is the final bit of code to allow enabling swiotlb on
mpc86xx. The platform-specific code is very small and consists
of enabling SWIOTLB in the config file, registering the
swiotlb_setup_bus_notifier initcall, and setting pci_dma_ops
to point to swiotlb_pci_dma_ops if we have more memory than
can be mapped by the inbound PCI windows.

CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.
This removes it along with the following changes:
- 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
on 6xx which is what they want anyway.
- A new symbol, PPC_BOOK3S, is defined that represent compliance with
the "Server" variant of the architecture. This is set when either 6xx
or PPC64 is set and open the door for future BOOK3E 64-bit.
- 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
PPC64 && PPC_BOOK3S
- A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
used to control the use of prom_init.c

Basic support for the GPIO available on the SBC610 VPX Single Board Computer
from GE Fanuc (PowerPC MPC8641D).
This patch adds basic support for the GPIO in the devices I/O FPGA, the GPIO
functionality is exposed through the AFIX pins on the backplane, unless used
by an AFIX card.
This code currently does not support switching between totem-pole and
open-drain outputs (when used as outputs, GPIOs default to totem-pole).
The interrupt capabilites of the GPIO lines is also not currently supported.

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression. This
patch makes this easier by changing:
bool "PCI support" if <long expression>
to
bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.
Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

There isn't any reason at this point that we can't build 82xx, 83xx & 86xx
support in with the other 6xx based boards. Twiddle the Kconfigs to allow
this.
This allows us to remove the machine type selection for related to 6xx.

The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function. Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:
PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15
Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.
Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.
Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

Make it so we do a runtime check to know if we need to write cfg_addr
as big or little endian. This is needed if we want to allow 86xx support
to co-exist in the same kernel as other 6xx PPCs.

arch/powerpc/platforms/86xx/pci.c -> arch/powerpc/sysdev/fsl_pci.c
arch/powerpc/sysdev/fsl_pcie.h -> arch/powerpc/sysdev/fsl_pci.h
as the base to unify 83xx/85xx/86xx pci and pcie.

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.
Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.
