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:

*Enable SMEM MTD parser and its dependencies (SMEM & HW spinlocks) in

*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

6cc5919e8a ipq806x: disable DMA on the SPI flash
Previous patch 6f2905eeb6ce5ddec8d12d677e1f377a940b537b enabled ADM in
the kernel, which causes a kernel panic when accessing the SPI flash.

As a workaround, We'll disable DMA for the flash for now. It was not
enabled previously anyway so we'll just leave it as is.

They are enabled on both 3.18 and 4.1 kernel. Patches 150 to 154 are

ADM driver.

ADM engine is used by the NAND controller, so it is necessary to

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.

f74477de48 ipq806x: disable i2c device on gsbi4
Patch cherry-picked from the following location:
https://chromium-review.googlesource.com/#/c/269931/

Disable the i2c device on gsbi4 and mark gsbi4_h and gsbi4_qup clks as
unused. If they are enabled, clock framework will turn them off at end
of probe. On ipq806x by design gsbi4_qup, gsbi4_h clks and i2c on gsbi4
are meant for RPM usage. So turning them off in kernel is incorrect.

bdcba36442 ipq806x: fix boot freeze on zImage kernel
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
on most ARM architectures. This automatically calculate ZRELADDR by
masking PHYS_OFFSET with 0xf8000000.

On IPQ806x though, the first ~20MB of RAM is reserved for the hardware.
In newer bootloader, when DT is used, this is not a problem, we just
reserve this memory in the device tree. But if the bootloader doesn't
have DT support, then ATAGS have to be used. In this case, the ARM
decompressor will position the kernel in this low mem, which will not be
in the RAM section mapped by the bootloader, which means the kernel will
freeze in the middle of the boot process trying to map the memory.

As a work around, this patch allows disabling AUTO_ZRELADDR when
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
which don't support device-tree, which is the case on certain early
IPQ806x based designs.

This patch allows AP148 to boot from NOR flash.

As we're using a FIT image as kernel (which includes kernel bin + DTB)
