The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

1)Changes
- Rebased the patches for linux-4.4.7
- Added patch to fix spi nor fifo and dma support
- Added patch to configure watchdog barktime
2)Testing
Tested on IPQ AP148 Board:
a. NOR boot and NAND boot
b. ethernet network and ath10k wifi
c. ubi sysupgrade
UnTested
dwc3 usb has not been validated on IPQ board(AP148)
3)Known Issues:
Once we flash ubi image on AP148, and if we reset the board, uboot on
first boot creates PEB and LEB for dynamic sized partitions, which is incorrect
and not what linux expects which causes errors when trying to mount rootfs.
In order to test this, we can use the below steps:
a. Flash the ubi image on board and don't reset the board
b. load the kernel fit image in RAM and boot from there.

*Enable SMEM MTD parser and its dependencies (SMEM & HW spinlocks) in
the kernel config
*Replaces the MTD layout in DT by the dynamic layout provided by the
SMEM parser for AP148
Using the OF based parser is still possible on platforms which have a
fixed MTD partition layout.

Previous patch set backported the recently posted NAND flash driver to
3.18 and 4.1 kernel. This patch now enables it in the kernel config.
There is no change to the partition layout and init yet. But the NAND
flash can be seen in the mtd list on an AP148:
root@OpenWrt:/# cat /proc/mtd
dev: size erasesize name
mtd0: 10000000 00020000 "qcom-nandc"

These are cherry-picked & backported from LKML:
*https://lkml.org/lkml/2015/3/17/19
They are enabled on both 3.18 and 4.1 kernel. Patches 150 to 154 are
applying changes merged since 3.18; they enable mechanisms used by the
ADM driver.
ADM engine is used by the NAND controller, so it is necessary to
bring-up NAND flash support.

This change enable zImage+appended dtb support in ipq806x kernel
options. The zImage will now be generated as part of the kernel
binaries. Platforms which do not have DT support enabled in U-boot
can now make use of it by generating zImage files and appending dtb
to it.
It is not used yet but it is done as a stepping stone for early IPQ806x
platforms, which did not include DT support in U-boot.

This patch allows AP148 to boot from NOR flash.
As we're using a FIT image as kernel (which includes kernel bin + DTB)
we enable the MTD_SPLIT_FIT_FW kernel option, which will detect the FIT
image and automatically split the "firmware" partition into 2 MTD parts
(kernel + rootfs).
The rootfs will then be parsed and split between rootfs + rootfs_data,
as usual.

Patches in the ipq806x/patches folder were out of tree in v3.14. The
newest patch at the time was from June, so we can safely assume that
either the patches have been merged, or they have been rejected for
a good reason. If patches are seen missing, we'll cherry-pick them
on a per-needed basis.
This new kernel have been tested on AP148, which seems to works fine.

Patches numbered 76/77/102/103 have already been integrated in 3.14.12,
so they're not in this list.
All these patches are either integrated are pending integration into
kernel.org, therefore these patches should go away once the kernel
gets upgraded to 3.16.
Support is currently limited to AP148 board but can be extended to other
platforms in the future.
These changes do not cover ethernet connectivity.

The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which
in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration.
As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu
to the feature list. This will default the IMX6 target to use -mfloat-abi=hard
which will the be most efficient use of floating point.
When switching to hard float, we also need to enable VFP support in the kernel.
