Tobin C. Harding eb039161da powerpc/asm: Convert .llong directives to .8byte
.llong is an undocumented PPC specific directive. The generic
equivalent is .quad, but even better (because it's self describing) is
.8byte.

Convert all .llong directives to .8byte.

Dan Carpenter 8d046759f6 powerpc/44x: Fix mask and shift to zero bug
My static checker complains that 0x00001800 >> 13 is zero. Looking at
the context, it seems like a copy and paste bug from the line below
and probably 0x3 << 13 or 0x00006000 was intended.

Christophe Leroy 968159c003 powerpc/8xx: Getting rid of remaining use of CONFIG_8xx
Two config options exist to define powerpc MPC8xx:
* CONFIG_PPC_8xx
* CONFIG_8xx

arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"

arch/powerpc is now the only place with remaining use of
CONFIG_8xx: get rid of them.

Christophe Leroy 72e4b2cdf0 powerpc/time: refactor MFTB() to limit number of ifdefs
The 8xx cannot access the TBL and TBU registers using mfspr/mtspr
It must be accessed using mftb/mftbu

Due to this, there is a number of places with #ifdef CONFIG_8xx

This patch defines new macros MFTBL(x) and MFTBU(x) on the same model
as MFTB(x) and tries to make use of them as much as possible.

In arch/powerpc/include/asm/timex.h, we also remove the ifdef
for the asm() operands as the compiler doesn't mind unused operands

Michael Ellerman 65c5ec11c2 powerpc/boot: Fix 64-bit boot wrapper build with non-biarch compiler
Historically the boot wrapper was always built 32-bit big endian, even
for 64-bit kernels. That was because old firmwares didn't necessarily
support booting a 64-bit image. Because of that arch/powerpc/boot/Makefile
uses CROSS32CC for compilation.

However when we added 64-bit little endian support, we also added
support for building the boot wrapper 64-bit. However we kept using
CROSS32CC, because in most cases it is just CC and everything works.

However if the user doesn't specify CROSS32_COMPILE (which no one ever
does AFAIK), and CC is *not* biarch (32/64-bit capable), then CROSS32CC
becomes just "gcc". On native systems that is probably OK, but if we're
cross building it definitely isn't, leading to eg:

  gcc ... -m64 -mlittle-endian -mabi=elfv2 ... arch/powerpc/boot/cpm-serial.c
  gcc: error: unrecognized argument in option ‘-mabi=elfv2’
  gcc: error: unrecognized command line option ‘-mlittle-endian’
  make: *** [zImage] Error 2

To fix it, stop using CROSS32CC, because we may or may not be building
32-bit. Instead setup a BOOTCC, which defaults to CC, and only use
CROSS32_COMPILE if it's set and we're building for 32-bit.

But when matching using an OF table, both the vendor and device has to be

Olof Johansson d5d332d3f7 devicetree: Move include prefixes from arch to separate directory
We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.

Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.

As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.

Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.

As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

Linus Torvalds 38705613b7 powerpc updates for 4.11 part 1.
Highlights include:
 
  - Support for direct mapped LPC on POWER9, giving Linux direct access to
    devices that may be on there such as a UART.
 
  - Memory hotplug support for the Power9 Radix MMU.
 
  - Add new AUX vectors describing the processor's cache geometry, to be used by
    glibc.
 
  - The ability for a guest to ask the hypervisor to resize the guest's hash
    table, and in addition support for doing so automatically when memory is
    hotplugged into/out-of the guest. This allows the hash table to be sized
    based on the current memory usage of the guest, rather than the maximum
    possible memory usage.
 
  - Implementation of optprobes (kprobe optimisation) for powerpc.
 
 In addition there's the topic branch shared with the KVM tree, which includes
 support for guests to use the Radix MMU on Power9.

Nicholas Piggin ff45000fcb powerpc/boot: Request no dynamic linker for boot wrapper
The boot wrapper performs its own relocations and does not require
PT_INTERP segment. However currently we don't tell the linker that.

Prior to binutils 2.28 that works OK. But since binutils commit
1a9ccd70f9a7 ("Fix the linker so that it will not silently generate ELF
binaries with invalid program headers. Fix readelf to report such
invalid binaries.") binutils tries to create a program header segment
due to PT_INTERP, and the link fails because there is no space for it:

  ld: arch/powerpc/boot/zImage.pseries: Not enough room for program headers, try linking with -N
  ld: final link failed: Bad value

So tell the linker not to do that, by passing --no-dynamic-linker.

Michael Ellerman f0f7fe1ac3 powerpc/boot: Fix rebuild when changing kernel endian
Now that we don't set ARCH incorrectly when calling the boot Makefile,
we can use the generic cpp_lds_S rule for converting our zImage.lds.S
into zImage.lds.

The main advantage of using the generic rule is that it correctly uses
if_changed, which means we correctly regenerate the linker script when
switching endian. Fixing that means we are finally able to build one
endian and then rebuild the other endian without requiring to clean
between builds.

Oliver O'Halloran a1ff57416a powerpc/boot: Fix the early OPAL console wrappers
When configured with CONFIG_PPC_EARLY_DEBUG_OPAL=y the kernel expects
the OPAL entry and base addresses to be passed in r8 and r9
respectively. Currently the wrapper does not attempt to restore these
values before entering the decompressed kernel which causes the kernel
to branch into whatever happens to be in r9 when doing a write to the
OPAL console in early boot.

This patch adds a platform_ops hook that can be used to branch into the
new kernel. The OPAL console driver patches this at runtime so that if
the console is used it will be restored just prior to entering the
kernel.

The T4240RDB contains a W83793 hardware monitoring chip. Add a device
tree entry to make the driver attach to it, as the i2c-mpc bus driver
dropped support for class-based instantiation of devices a long time
ago.

Heiner Kallweit 65bc3ece84 powerpc/boot: Fix boot on systems with uncompressed kernel image
This commit broke boot on systems with an uncompressed kernel image,
namely systems using a cuImage. On such systems the compressed boot
image (boot wrapper, uncompressed kernel image, ..) is decompressed
by u-boot already, therefore the boot wrapper code sees an
uncompressed kernel image.

The old decompression code silently assumed an uncompressed kernel
image if it found no valid gzip signature, whilst the new code
bailed out in this case.

Fix this by re-introducing such a fallback if no valid compressed
image is found.

Oliver O'Halloran c762c69e10 powerpc/boot: Add support for XZ compression
This patch adds an option to use XZ compression for the kernel image.

Currently this is only enabled for 64-bit Book3S targets, which is
roughly equivalent to the platforms that use the kernel's zImage
wrapper, and that have been tested.

The bulk of the 32-bit platforms and 64-bit BookE use uboot images,
which relies on uboot implementing XZ. In future we can enable XZ
support for those targets once someone has tested it.

Oliver O'Halloran f1e510bbb9 powerpc/boot: Add XZ support to the wrapper script
This modifies the wrapper script so that the -Z option takes an argument
to specify the compression type. It can either be 'gz', 'xz' or 'none'.

The legazy --no-gzip and -z options are still supported and will set the
compression to none and gzip respectively, but they are not documented.

Only XZ -6 is used for compression rather than XZ -9. Using compression
levels higher than 6 requires the decompressor to build a large (64MB)
dictionary when decompressing and some environments cannot satisfy such
large allocations (e.g. POWER 6 LPAR partition firmware).

Oliver O'Halloran 1b7898ee27 powerpc/boot: Use the pre-boot decompression API
Currently the powerpc boot wrapper has its own wrapper around zlib to
handle decompressing gzipped kernels. The kernel decompressor library
functions now provide a generic interface that can be used in the
pre-boot environment. This allows boot wrappers to easily support
different compression algorithms. This patch converts the wrapper to use
this new API, but does not add support for using new algorithms.

Oliver O'Halloran 22750d98b0 powerpc/boot: Use CONFIG_KERNEL_GZIP
Most architectures allow the compression algorithm used to produced the
vmlinuz image to be selected as a kernel config option. In preperation
for supporting algorithms other than gzip in the powerpc boot wrapper
the makefile needs to be modified to use these config options.

Oliver O'Halloran 1a13de6df9 powerpc/boot: Add sed script
The powerpc boot wrapper is potentially compiled with a separate
toolchain and/or toolchain flags than the rest of the kernel. The usual
case is a 64-bit big endian kernel builds a 32-bit big endian wrapper.

The main problem with this is that the wrapper does not have access to
the kernel headers (without a lot of gross hacks). To get around this
the required headers are copied into the build directory via several sed
scripts which rewrite problematic includes. This patch moves these
fixups out of the makefile into a separate .sed script file to clean up
makefile slightly.

Michael Ellerman 6abe248e16 powerpc/boot: Use $(Q) to quiet build rules not @
Some of the rules in the boot Makefile use @ to hide the command, this
means "make V=1" doesn't show them, which is confusing.

So use the Kbuild standard $(Q) which means KBUILD_VERBOSE=1 or V=1 will
work as expected.

Replace the non-standard vendor prefix stm and st-micro with st for
STMicroelectronics. The drivers do not specify the vendor prefixes
since the I2C Core strips them away from the DT provided compatible
string. Therefore, changing existing device trees does not have any
impact on device detection.

Arnd Bergmann 58ab5e0c2c Kbuild: arch: look for generated headers in obtree
There are very few files that need add an -I$(obj) gcc for the preprocessor
or the assembler. For C files, we add always these for both the objtree and
srctree, but for the other ones we require the Makefile to add them, and
Kbuild then adds it for both trees.

As a preparation for changing the meaning of the -I$(obj) directive to
only refer to the srctree, this changes the two instances in arch/x86 to use
an explictit $(objtree) prefix where needed, otherwise we won't find the
headers any more, as reported by the kbuild 0day builder.

Alessio Igor Bogani 97493e2e9e powerpc/86xx: Add support for Emerson/Artesyn MVME7100
Add support for the Artesyn MVME7100 Single Board Computer.

The MVME7100 is a 6U form factor VME64 computer with:

    - 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)
    Watchdog, USB, NVRAM, NOR, NAND, EEPROMs, VME, PMC/XMC and RTC

Oliver O'Halloran 656ad58ef1 powerpc/boot: Add OPAL console to epapr wrappers
This patch adds an OPAL console backend to the powerpc boot wrapper so
that decompression failures inside the wrapper can be reported to the
user. This is important since it typically indicates data corruption in
the firmware and other nasty things.

Currently this only works when building a little endian kernel. When
compiling a 64 bit BE kernel the wrapper is always build 32 bit to be
compatible with some 32 bit firmwares. BE support will be added at a
later date. Another limitation of this is that only the "raw" type of
OPAL console is supported, however machines that provide a hvsi console
also provide a raw console so this is not an issue in practice.

Paul Gortmaker 5b01310cfc powerpc/sbc8641: drop bogus PHY IRQ entries from DTS file
This file was originally cloned off of the MPC8641D-HPCN reference
platform, which actually had a PHY IRQ line connected. However this
board does not. The bogus entry was largely inert and went undetected
until commit 321beec504 ("net: phy: Use
interrupts when available in NOLINK state") was added to the tree.

With the above commit, the board fails to NFS boot since it sits waiting
for a PHY IRQ event that of course never arrives. Removing the bogus
entries from the DTS file fixes the issue.

In u-boot, when set the video as console, the name 'vga' is used
as a general name for the video device, during the fdt_fixup_stdout
process, the 'vga' name is used to search in the dtb to setup the
'linux,stdout-path' node. Though the P1022 DIU is not VGA-compatible
device, to meet the 'vga' name used in u-boot, the vga alias node is
added for P1022 in this patch. At the same time, a display alias is
also added so that no other components grow dependencies on the vga
alias node.

Michael Ellerman bf4981a006 powerpc: Remove the celleb support
The celleb code has seen no actual development for ~7 years.

We (maintainers) have no access to test hardware, and it is highly
likely the code has bit-rotted.

As far as we're aware the hardware was never widely available, and is
certainly no longer available, and no one on the list has shown any
interest in it over the years.

So remove it. If anyone has one and cares please speak up.

Jeremy Kerr 7f664cf9e4 powerpc/boot: don't clobber r6 and r7 in epapr boot
We use r6 and r7 for epapr boot, but the current pre-C init will clobber
both of these.

This change does a simple replacement, of r6 -> r12 and r7 -> r13, so
that we hit platform init with these registers intact.

Jeremy Kerr 8c06f0d910 powerpc/boot: Fix stack corruption in epapr entry point
Currently, a 64-bit little-endian zImage.epapr won't boot in epapr mode,
as we never return from platform_init.

Before entering C, we initialise our stack by setting r1 16 bytes below
the end of the _bss_stack:

  stwu	r0,-16(r1)	/* establish a stack frame */

However, the called function will save the caller's lr in the caller's
frame's lr save area, at -16(r1) to -32(r1).

This means that writes to the fdt variable will corrupt the saved link
register:

 0000000020c06018 l     O .bss   0000000000001000 _bss_stack
 0000000020c07018 l     O .bss   0000000000000008 fdt

We'll need at least 32 bytes in the initial stack frame, to handle the
LR save area. We bump this to 112 bytes, as that'll be the max required
by ABIv1.

Thanks to Alistair Popple for debugging help.

We'll likely be entering the zImage.epapr as BE, so include the pseries
implementation of _zimage_start, which adds the endian fixup magic.

Although the endian fixup won't work on Book III-E machines starting LE,
the current entry point doesn't support LE anyway, so we shouldn't be
breaking anything.
