ARM: imx: stop adjusting ar8031 phy tx delay
Recent changes to the Atheros at803x driver cause
the approach taken here to stop working because
commit
6d4cd041f0af
("net: phy: at803x: disable delay only for RGMII mode")
and commit
cd28d1d6e52e
("net: phy: at803x: Disable phy delay for RGMII mode")
fix the AR8031 driver to configure the phy's (RX/TX)
delays as per the 'phy-mode' in the device tree.
In particular, the phy tx (and rx) delays are updated
again as per the 'phy-mode' *after* the code in here
runs.
Things worked before above commits, because the AR8031
comes out of reset with RX delay enabled, and the
at803x driver didn't touch the delay configuration at
all when "rgmii" mode was selected.
It appears the code in here tries to make device
trees work that incorrectly specify "rgmii", but
that can't work any more and it is imperative since
above commits to have the phy-mode configured
correctly in the device tree.
I suspect there are a few imx7d based boards using
the ar8031 phy and phy-mode = "rgmii", but given I
don't know which ones exactly, I am not in a
position to update the respective device trees.
Hence this patch is simply removing the superfluous
code from the imx7d initialisation. An alternative
could be to add a warning instead, but that would
penalize all boards that have been updated already.

ARM: at91: move platform-specific asm-offset.h to arch/arm/mach-at91
<generated/at91_pm_data-offsets.h> is only generated and included by
arch/arm/mach-at91/, so it does not need to reside in the globally
visible include/generated/.
I renamed it to arch/arm/mach-at91/pm_data-offsets.h since the prefix
'at91_' is just redundant in mach-at91/.
My main motivation of this change is to avoid the race condition for
the parallel build (-j) when CONFIG_IKHEADERS is enabled.
When it is enabled, all the headers under include/ are archived into
kernel/kheaders_data.tar.xz and exposed in the sysfs.
In the parallel build, we have no idea in which order files are built.
- If at91_pm_data-offsets.h is built before kheaders_data.tar.xz,
the header will be included in the archive. Probably nobody will
use it, but it is harmless except that it will increase the archive
size needlessly.
- If kheaders_data.tar.xz is built before at91_pm_data-offsets.h,
the header will not be included in the archive. However, in the next
build, the archive will be re-generated to include the newly-found
at91_pm_data-offsets.h. This is not nice from the build system point
of view.
- If at91_pm_data-offsets.h and kheaders_data.tar.xz are built at the
same time, the corrupted header might be included in the archive,
which does not look nice either.
This commit fixes the race.

ARM: orion/mvebu: unify debug-ll virtual addresses
In a multiplatform configuration, enabling DEBUG_LL breaks booting
on all platforms with incompatible settings. In case of the Marvell
platforms of the Orion/MVEBU family, the physical addresses are
all the same, we just map them at different virtual addresses,
which makes it impossible to run a kernel with DEBUG_LL enabled on
a combination of the merged mvebu and the legacy boardfile based
platforms.
This is easily solved by using the same virtual address everywhere.
I picked the address that is already used by mach-mvebu for UART0:
0xfec12000. All these platforms have a 1MB region with their internal
registers, almost always at physical address 0xf1000000, so I'm
updating the iotable for that entry.
In case of mach-dove, this is slightly trickier, as the existing
mapping is 8MB and a second 8MB mapping is already at the 0xfec00000
address. I have verified from the datasheet that the last 7MB of the
physical mapping are "reserved" and nothing in Linux tries to use
it either. I'm putting this 1MB mapping at the same address as the
others, and the second 8MB register area immediately before that.

dma: iop-adma: allow building without platform headers
Now that iop3xx and iop13xx are gone, the iop-adma driver no
longer needs to deal with incompatible register layout defined

Move the iop32x specific definitions into drivers/dma/iop-adma.h
and the platform_data into include/linux/platform_data/dma-iop32x.h,
and change the machine code to no longer reference those.
The DMA0_ID/DMA1_ID/AAU_ID macros are required as part of the

ARM: remove Intel iop33x and iop13xx support
There are three families of IOP machines we support in Linux: iop32x
(which includes EP80219), iop33x and iop13xx (aka IOP34x aka WP8134x).
All products we support in the kernel are based on the first of these,
iop32x, the other families only ever supported the Intel reference
boards but no actual machine anyone could ever buy.
While one could clearly make them all three work in a single kernel
with some work, this takes the easy way out, removing the later two
platforms entirely, under the assumption that there are no remaining
users.
Earlier versions of OpenWRT and Debian both had support for iop32x
but not the others, and they both dropped iop32x as well in their 2015
releases.

From all I can tell, this platform is no longer being used
with modern kernels, based on various indications:
- The supported chips (nuc910/950/960) are no longer marketed
by the manufacturer
- Newer chips from the same family (nuc97x, nuc980, n329x)
that are still marketed have Linux BSPs but those were never
submitted for upstream inclusion.
- The last patch from the platform maintainer was in 2011.
- All patches to w90x900 platform specific files afterwards
are cleanups that were apparently done without access to
test hardware.

kbuild: show hint if subdir-y/m is used to visit module Makefile
Since commit
ff9b45c55b26 ("kbuild: modpost: read modules.order instead
of $(MODVERDIR)/*.mod"), a module is no longer built in the following
pattern:
[Makefile]
subdir-y := some-module
[some-module/Makefile]
obj-m := some-module.o
You cannot write Makefile this way in upstream because modules.order is
not correctly generated. subdir-y is used to descend to a sub-directory
that builds tools, device trees, etc.
For external modules, the modules order does not matter. So, the
Makefile above was known to work.
I believe the Makefile should be re-written as follows:
[Makefile]
obj-m := some-module/
[some-module/Makefile]
obj-m := some-module.o
However, people will have no idea if their Makefile suddenly stops
working. In fact, I received questions from multiple people.
Show a warning for a while if obj-m is specified in a Makefile visited
by subdir-y or subdir-m.
I touched the %/ rule to avoid false-positive warnings for the single
target.

generate modules.order in directories visited by subdir-y or subdir-m
