This reverts commit 7e88753ace.
Using subpartitions (hierarchical layout) resulted in calling MTD ops of
parent partition instead of master device ops. That was expected and
should work but testing revealed some bugs.
Apparently the way MTD_ERASE_PARTIAL is implemented in the OpenWrt
breaks something and using parent partition ops triggers using that
code.
On SmartRG SR400ac it was resulting in:
[ 225.487519] jffs2: Erase at 0x01ac0000 failed immediately: errno -22
on the second boot (for some reason erasing was starting over) and it
was breaking flash access in a long term.

This helper uses hierarchical partitions layout following the way
upstream parsers work. It's closer to what we should use when mainlining
our solutions. It also doesn't require hacky casting of struct
mtd_partition to the const.
THIS WILL AFFECT KERNEL PRINTING PARTITIONS IN THE LOG
Something like:
[ 3.930158] 0x0000004e0000-0x000001fb0000 : "rootfs_data"
will get replaced by:
[ 3.907338] Creating 1 MTD partitions on "rootfs":
[ 3.912142] 0x00000031d400-0x000001ded400 : "rootfs_data"
It's important to understand that "rootfs_data" in above example is a
*subpartition* of the "rootfs" now. To get absolute addresses (e.g. for
some debugging purposes) one has to add them to the "rootfs", e.g.
[ 3.912548] 0x0000001c2c00-0x000001fb0000 : "rootfs"
(0x1c2c00 + 0x31d400 = 0x4e0000)

No single target/arch uses it and most likely there is no need to make
such a potential code target/arch specific.

If "compatible" is being used that should trigger a proper parser
directly. It's more reliable thanks to not trying parsers one by one. In
such case partition shouldn't be split automatically to avoid parsing it
twice.

It makes more sense to add run_parsers_by_type() in a patch that
introduces parser types. That makes the other one just add a code using
it.

This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).
It's required to successfully backport support for new devices using
that new syntax in their DT files.
Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

This backports upstream support for "compatible" DT property set for the
"partitions" subnode of flash node. It allows specifying how partitions
should be created/parsed. Right now only "fixed-partitions" is
supported.
It should eventually replace our downstream "linux,part-probe" solution.

This adds initial support for kernel 4.14 based on the patches for
kernel 4.9.
In the configuration I deactivated some of the new possible security
features like:
CONFIG_REFCOUNT_FULL
CONFIG_SLAB_FREELIST_HARDENED
CONFIG_SOFTLOCKUP_DETECTOR
CONFIG_WARN_ALL_UNSEEDED_RANDOM
And these overlay FS options are also deactivated:
CONFIG_OVERLAY_FS_INDEX
CONFIG_OVERLAY_FS_REDIRECT_DIR
I activated this:
CONFIG_FORTIFY_SOURCE
CONFIG_POSIX_TIMERS
CONFIG_SLAB_MERGE_DEFAULT
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED
I am not sure if I did the porting correct for the following patches:
target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch
target/linux/generic/hack-4.14/220-gc_sections.patch

Except for renames and line changes the only conflict was in
allocate_partition in handling MTD_WRITEABLE. Hopefully it was handled
correctly.

In old days mtd_add_partition was checking for partitions overlapping
which was breaking our splitting feature. We had to modify this function
by adding an extra bool dup_check parameter. Upstream commit:
3a434f66e6da ("mtd: part: Remove partition overlap checks")
removed that check so we don't need our modification anymore.

The "linux,part-probe" dts parsing is a pretty neat generic feature.
It has been posted to kernel.org and could easily be reused by all
targets.
This change moves the patch to the 3.18 and 4.1 generic folders, and
makes the feature available to all platforms who may want to use it.
