82fb27917b ipq806x: fix uninitialized variable usage in cpufreq-krait
In krait_cpufreq_probe, both freq and max_cpu_freq are never
initialized, so the max_cpu_freq will have a random value at the end.
Fix this by properly initializing max_cpu_freq to 0 and storing the clk
frequency in freq as well, to make it similar to how it's calculated in
krait_set_target.

Fixes the following warnings:

b0b59a8e75 ipq806x: switch AP148 to using SMEM based MTD parser
*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.

This patch just modifies the kernel code, but doesn't change the config.

c7bf2accc9 ipq806x: Add ADM support
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.

0f7de49fa3 ipq806x: fix freeze in PCIe code when booting with an old u-boot
Old bootloader (same ones which have DT disabled) don't perform any PCIe
initialization. The consequence is a freeze during PCIe bring-up on
these old u-boot. Same kernel with a newer bootloaders works fine as
they contain the corresponding PCIe init code.

In this change, we'll add the missing init and make sure the kernel
doesn't rely on some preexisting init to get PCIe to work. That includes
the following changes:
*GPIOs: set function & drive strength
*Clocks: add init code for aux & ref clocks
*PCIe driver: additional init of the hardware controller

Tested 3.18 and 4.1 on an AP148 with bootloader branch 0.0.1

c4c986e419 ipq806x: add support for non-dt enabled ap148 bootloader
Certain AP148 platforms (and derivative) use bootloaders which did not
have DT enabled.
In order to support these old platforms, we'll now make the following
modifications:
*explicitely add the memory node in the AP148 DT: this used to be added
 by new u-boot through a run-time patch mechanism. We'll now add it
 explicitely so it works on boots which don't support that feature. New
 boots will have the node twice, the second one will be ignored.
*add the zImage generation next to the FIT image for AP148.

Other platforms using non-DT enabled bootloaders may want to leverage
this zImage code to generate their own firmare as well.
