This imports the tools/include dir from the Kernel as of 4.5-rc1 to
barebox.
The Kernel has many useful defines and helpers which are often
duplicated in the different tools. Let's create a copy of them
in a common place for all tools.
Some files have been skipped for now as I currently see no use for them:
include/linux/filter.h
include/linux/hash.h
include/linux/rbtree.h
include/linux/rbtree_augmented.h
They can be added later if needed.

Setting a fixed memory size prevents from using the different board
variants with different memories equipped.
barebox is able to read RAM size informations from the imx53 RAM
controller and thus does not require this information passed via dts.

Claiming that all of PXA has CLK implemented, while only PXA3XX
selects the relevant clock implementations causes lots of build
failures for the other PXA architectures.
Fix it by moving the HAVE_CLK select to the one PXA arch, that
actually has it.

imx233-olinuxino is commonly powered from external input supply,

As the i.MX6 PCIe core doesn't have a software reachable reset
wired up, it's hard for any driver to get the core into a known
good state.
To make it easier for whatever software follows barebox, bring
back the core into a safe state before leaving barebox.

When booting Barebox in the HW environment where PCIe core has been
used but not properly shut down, writing to PCIE_PL_PFLR in
imx6_pcie_assert_core_reset would cause data abort exception.
The problem can be easily reproduced on a i.MX6 based board with PCIe
slot populated with some device by doing:
> bootm -f -e 0x1050 <your board's>.img
Ignoring this exception seem to allow PCIe core to successfully
initialize and enumerate devices properly. This is also how Linux
Kernel version of the driver handles this situation -- it installs
dummy no-op abort handler at the beginning of device's probing.

Originally it was intended to further extend the multi string property
device-path further with more elements, like for example a filename. It
turned out though that this is too complex and instead of further
extending the property we should instead create additional properties,
so this mechanism is removed with this patch to make the code simpler.

OF fixups cm_cogent_fixup() and hb_fixup() are supposed to modify the
Linux device tree. And they did originally, but commit
e520a8cc46 changed them to use
for_each_compatible_node(), which iterates through the Barebox DT.
Use new for_each_compatible_node_from() to specify the Linux DT root

The existing iterator for_each_compatible_node() searches for each
compatible node starting from the root of the loaded device tree.
This means it only works on the barebox device tree and not the tree
to be passed to the Linux kernel, which is what an of_fixup would
probably want to use.
This adds for_each_compatible_node_from(), which takes an additional
parameter of a root to search from. This could be the device tree to
be used for the kernel. It could also be used to search just a
subtree.

socfpga would load the environment from a file named "barebox.env"
located on the device "/dev/mmc0.1". Both those names are hard-coded
in the socfpga code and can't be changed.
Barebox supports selecting the location of the environment using a
"barebox,environment" node in device tree's "chosen" node. And
recently supports specifying that the env should come from a file on
this device.
Change socfpga to use this mechanism by adding the appropriate device
node.

Current barebox,environment node only allows specifying a raw device or
partition to load an environment from. Some boards, like OMAP and
SoCFPGA, instead want to use a file located in a FAT filesystem.
Extend the device tree bindings with a new property 'file-path' that
will trigger this behavior.
This allows any board using this driver to get the env from a file or
from a raw device, instead of each machine type being either raw
device only or file only.

If a new cdev doesn't have a device_node defined when passed to
devfs_create(), set it to the device_node of the parent device, if one
exists.
For non-partitions, like ocotp or eeprom devices, this is the correct
thing to do. Partitions need to use, and do use, a different node.
The code from commit 274e0b8dc4 to set
device_node in ocotp can be removed.

In commit 75b682795e using a path that
has a partition description broke.
Fix this and simpfy the code some.
There is no need to loop over each string in the path property: it's
defined to have at most one parition description, no extant dts has
more than one, and how it would handle more than one didn't make sense
anyway.
Once not looping, __of_find_path() just needs the partition
description text, not both the original node and property name to look
it up from.
When using a partition description, don't lookup the cdev of the node
just to replace it with the partition's cdev.
