645b163cfc ar71xx: fix regression in 74x164 initialization with 4.9
The memcpy of the init data relies on chip->registers to be initialized,
which only happens later in the code. Move this initialization further
down to make it work.
This was breaking PCIe/USB on some MikroTik RouterBoard devices.

c078386ae3 ar71xx: only use SPI NOR 4K sectors on smaller flash chips for mikrotik devices
On NOR based Mikrotik devices, 4K sectors significantly slow down
firmware flashing and jffs2 usage. On NAND based devices they may be
necessary to run rbcfg (the boot loader config is often on SPI NOR).

c08293893a kernel: add support for limiting 4K erase sector support based on flash chip size
Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.

Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.

c4c72a9a42 ar71xx: fix LED config for DIR-869 A1
This fixes the LED configuration for the D-Link DIR-869 A1. In order to
support the device I probed around using an initramfs image for the
UniFi AC. Pulling GPIO 15 to low enabled the LEDs while high disabled them.
GPIO 16 set to low meant that the color was white while pulling it to high
made the color change to orange. The past code was written based upon these
findings.
However, running a flashed image I now discovered that GPIO 15 controls the
orange LEDs while GPIO 16 controls the white ones and that both are active
when low. This means that the GPIOs were inverted and one active_low was set
wrong which this patch fixes.

Behavior of the LED front after this patch is applied:

cat /sys/devices/platform/leds-gpio/leds/d-link:white:status/brightness
0   -> white LEDs are OFF
255 -> white LEDs are ON

cat /sys/devices/platform/leds-gpio/leds/d-link🍊status/brightness
0   -> orange LEDs are OFF
255 -> orange LEDs are ON

If the brightness of both is set to 255 the LED front will be white.
If the brightness of both is set to 0 the LED front will be off.

443abb8ccd ar71xx: add support for Mikrotik RB750P-PBr2
Specifications:
- SoC: Qualcomm QCA9531 (650MHz)
- RAM: 64MB
- Storage: 16MB NOR SPI flash
- Ethernet: 5x100M (1 PoE in, 4 PoE out)
- Outdoor use ready

This ethernet router is based on the same platform as the hEX PoE lite.

Installation

1. login to the Mikrotik WebUI to backup your licence keys
2. setup a DHCP/BOOTP Server with:
     * DHCP-Option 66 (TFTP server name) pointing to a local TFTP
       Server within the same subnet of the DHCP range
     * DHCP-Option 67 (Bootfile-Name) matching the initramfs filename
       of the to be booted image
3. connect the port labled internet to your local network
4. keep the reset button pushed down and power on the board

The board should load and start the initramfs image from the TFTP
Server. Login as root/without password to the started LEDE via ssh
listing on IPv4 address 192.168.1.1. Use sysupgrade to install LEDE.

Revert to RouterOS

Use the "rbcfg" package on in LEDE:
  * rbcfg set boot_protocol bootp
  * rbcfg set boot_device ethnand
  * rbcfg apply

Open Netinstall and reboot routerboard. Now netinstall sees routerboard
and you can install RouterOS. If NetInstall gets stuck on Sending offer
just wait for it to timeout and then close and open Netinstall again.

Click on install again.

In order for RouterOS to function properly, you need to restore license
for the device. You can do that by including license in NetInstall

b3cb0e7588 firmware-utils: mktplinkfw: rework combined image option
We use combined option in "mktplinkfw" tool for generating initramfs
kernel images and header for kernel inside "safeloader" image type (in
fact, only for TL-WR1043ND v4 at this moment).

There is also "mktplinkfw-kernel" tool, a stripped-down version, used
only for generating "simple" header, for safeloader image types.

This changes how "mktplinkfw" handles combined images (which then will
allow us to drop the stripped-down version of the tool):

- drop "ignore size" command line option (it was used only for combined
  images anyway)
- don't require "flash layout id" for combined images (we don't need and
  shouldn't limit size of the initramfs kernel and for kernels inside
  safeloader images, the "tplink-safeloader" tool does the size check)
- require kernel address and entry point in command line parameters for
  combined images (consequence of previous point)
- don't include md5 sum and firmware length values in header (they are
  needed only for update from vendor GUI and are ingored in case of
  initramfs and "tplink-safeloader" images)
- drop "fake" flash layout for TL-WR1043ND v4 as it's no longer needed

Also, adjust "mktplinkfw-combined" command in ar71xx/image/tp-link.mk to
match introduced changes in "mktplinkfw" tool.
