ebaa82a2ca apm821xx: consolidate apm821xx device trees files
This patch moves the common SoC device tree entries
from the currently four supported platforms into a
common apm82181.dtsi.

Furthermore, this patch also changes the GPIO, IRQ and
input definitions of the supported platforms to use the
defined dt-bindings macros for GPIO_ACTIVE_LOW|HIGH,
KEY_WPS|RESTART|*, IRQ_TYPE_* when it's appropriate.

3a112113e7 apm821xx: add amcc, usb-otg-405ex devicetree definition
This patch adds support for the amcc,usb-otg-405ex device
which is found in all APM82181 SoCs.
Note: The system can't use the generic "snps,dwc2" compatible
because of the special ahbcfg configuration. The default
GAHBCFG_HBSTLEN_INCR4 of snps,dwc2 can cause a system hang
when the USB and SATA is used concurrently.

07bc0d6089 lantiq: fix pci issue if mem kernel parameter is used
As specified by e0229a16b0 if the VR9
based router provides FXS ports and they should enabled then the
following must added to the kernel command line:

  mem=[TOTALMEMSIZE-2M] vpe1_load_addr=ADDRESS vpe1_mem=2M

By adding mem= parameter a pci device stop working correctly. The
pci-lantiq.c module use get_num_physpages() to compute dynamically the
memory amount of the board.

The mem= make the module to compute in the wrong way the BAR11MASK, so
in this situation the mask is misaligned with the dma area that the
hardware expects.

This patch is a port of what legacy ifxmips_pci.c does.

cc5c8f681e ramips: add TEW-691GR/TEW-692GR 2.4 GHz interface mac addresses
Assign an unused MAC addresses to the 2.4GHz wifi interface as it was
originally planed but not possible.

The MAC address numbering of the TEW-691GR changes to the following
pattern:

  LAN:  AA:BB:CC:DD:EE:0C
  WIFI: AA:BB:CC:DD:EE:0D
  WAN:  AA:BB:CC:DD:EE:0F

The MAC address numbering of the TEW-692GR changes to the following

  LAN:    AA:BB:CC:DD:EE:e4
  WAN:    AA:BB:CC:DD:EE:e5
  2.4GHz: AA:BB:CC:DD:EE:e7

Set the label and compatible string for the TEW-692GR PCIe wireless
according to the the PCI binding documentation.

Use the wifi@0,0 label and the pci0,0 compatible string since the PCI
vendor and device id is unknown. It should work anyway since the
compatible string isn't evaluated (yet).

faf94d926e ramips: add support for MikroTik hEX v3 (RB750Gr3)
The MikroTik hEX v3 (RB750Gr3) is a MT7621AT board which is similar to most MT7621 reference designs, it can be easily supported by this patch; however, the stock RouterBOOT bootloader has to be replaced by a MT7621 SDK U-Boot such as https://github.com/ndoo/RB750Gr3-U-Boot - U-Boot configured for the RB750Gr3 (16MiB SPI flash, 256MiB DDR3 RAM at 1200MHz).

RouterBOOT, the stock bootloader, does not initialize the UART and boots silently, making it preferable to replace it with a MT7621 SDK U-Boot with UART (57600 8N1) that supports HTTP, TFTP or serial upload of sysupgrade firmware and U-Boot.

Furthermore, RouterOS, the stock firmware, is contained in a proprietary modification of SquashFS without GPL sources; UART is also disabled in stock firmware.

The combination of LEDE firmware generated by this PR and MT7621 SDK U-Boot expects the printed MAC address to reside at offset `0xe000` of the factory partition (absolute offset is `0x4e000`); this is similar to the factory MAC address offset for several other MT7621 devices.

A 16MiB flash dump suitable for use with flashrom will be provided if/once this patch is accepted and binaries are built by LEDE buildbot. Alternatively, writing the U-Boot to the SPI flash starting at 0x0 offset and booting the board with serial console attached will allow TFTP, HTTP or serial upload of sysupgrade firmware.

15a14cf166 layerscape: add 64b/32b target for ls1012ardb device
The QorIQ LS1012A processor, optimized for battery-backed or
USB-powered, integrates a single ARM Cortex-A53 core with a hardware
packet forwarding engine and high-speed interfaces to deliver
line-rate networking performance.
QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
development platform, with a complete debugging environment.
The LS1012ARDB board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

LEDE/OPENWRT will auto strip executable program file while make. So we
need select CONFIG_NO_STRIP=y while make menuconfig to avoid the ppfe network
fiemware be destroyed, then run make to build ls1012ardb firmware.

The fsl-quadspi flash with jffs2 fs is unstable and arise some failed message.
This issue have noticed the IP owner for investigate, hope he can solve it
earlier. So the ls1012ardb now also provide a xx-firmware.ext4.bin as default
firmware, and the uboot bootcmd will run wrtboot_ext4rfs for "rootfstype=ext4"
bootargs.

e0229a16b0 lantiq: added support for VPE1
Created minimal patchset based on BB rev 43158 by Eddi De Pieri
14.07/openwrt.git 79472c025449efae9310defad0d3a73cff14d756

If the VR9 based router provides FXS ports and they shoud enabled then
the following must added to the kernel command line:
mem=[TOTALMEMSIZE-2M] vpe1_load_addr=ADDRESS vpe1_mem=2M maxvpes=1
maxtcs=1

To use FXS 2M of RAM are needed for the VPE firmware. The size is set
by vpe1_mem.
The available RAM must be reduced by this size using the mem argument.
A correct load address (example 0x83e00000) for the firmware must be given,
too.
