The chip supports clock speeds up to 50 MHz, however it won't even read
the chip-id correctly at this frequency.

45 MHz however works reliable.

Fixes commit 91a52f22 ("treewide: backport support for nvmem on non platform devices")

Signed-off-by: David Bauer <mail@david-bauer.net>

When a target configuration has unser Kconfig symbols, the build will
fail when OpenWrt is compiled with V=s and stdin is connected to a tty.

In case OpenWrt is compiled without either of these preconditions, the
build will uscceed with the symbols in question being unset.

Modify the kernel configuration in a way it fails on unset symbols
regardless of the aformentioned preconditions.

Calling free for the OF property can result in a kernel panic, as the
buffer in question might be referenced elsewhere. Also, it is not
removed from the tree.

Always allocate a new property and updating the tree with it fixes both
issues.

The change which backported the of_get_mac_address() change broke some
patches in the layerscape target so the patches did not apply any more.

This patch is backported from linux-arm-kernel [1] to improve situation, when
it was reported that 1.2 GHz variant is unstable with DFS.
It waits to be accepted upstream, however, it waits for Marvell people to respond.

Based on the discussion on the mailing list [1], the patch which was
reverted, it reverts only one patch without the subsequent ones.

This leads to the SoC scaling issue not using a CPU parent clock, but
it uses DDR clock. This is done for all variants, and it's wrong because
commits (hacks) that were using the DDR clock are no longer in the mainline kernel.

If someone has stability issues on 1.2 GHz, it should not affect all
routers (1 GHz, 800 MHz) and it should be rather consulted with guys, who are trying to
improve the situation in the kernel and not making the situation worse.

There are two solutions in cases of instability:
a) disable cpufreq
b) underclock it up to 1 GHz

This reverts commit 080a0b74.

"In case SFP module is present, U-Boot has to enable the sfp node above,
remove phy-handle property, and add managed = "in-band-status" property."

The GL-X300B is a industrial 4G LTE router based on the Qualcomm
QCA9531 SoC.

Specifications:
 - Qualcomm QCA9531 @ 650 MHz
 - 128 MB of RAM
 - 16 MB of SPI NOR FLASH
 - 2x 10/100 Mbps Ethernet
 - 2.4GHz 802.11b/g/n
 - 1x USB 2.0 (vbus driven by GPIO)
 - 4x LED, driven by GPIO
 - 1x button (reset)
 - 1x mini pci-e slot (vcc driven by GPIO)
 - RS-485 Serial Port (untested)

Flash instructions:

This firmware can be flashed using either sysupgrade from the GL.iNet
firmware or the recovery console as follows:

 - Press and hold the reset button
 - Connect power to the router, wait five seconds
 - Manually configure 192.168.1.2/24 on your computer, connect to
   192.168.1.1
 - Upload the firmware image using the web interface

RS-485 serial port is untested and may depend on the following commit in
the GL.iNet repo:

https://github.com/gl-inet/openwrt/commit/202e83a32ae308fbb70502b6dbe3bb0bf8b1fba9

MAC addresses as verified by OEM firmware:

vendor   OpenWrt   address
WAN      eth0      label
LAN      eth1      label + 1
2g       phy0      label + 2

The label MAC address was found in the art partition at 0x0
