f7a43e4606 mpc85xx: add SPI kernel loader for TP-Link TL-WDR4900 v1
Similar to the lzma-loader on our MIPS targets, the spi-loader acts as
a second-stage loader that will then load and start the actual kernel.
As the TL-WDR4900 uses SPI-NOR and the P1010 family does not have support
for memory mapping of this type of flash, this loader needs to contain a
basic driver for the FSL ESPI controller.

2050bc4f64 ramips: add support for ZyXEL NWA50AX / NWA55AXE
Hardware
--------
CPU:    Mediatek MT7621
RAM:    256M DDR3
FLASH:  128M NAND
ETH:    1x Gigabit Ethernet
WiFi:   Mediatek MT7915 (2.4/5GHz 802.11ax 2x2 DBDC)
BTN:    1x Reset (NWA50AX only)
LED:    1x Multi-Color (NWA50AX only)

UART Console
------------
NWA50AX:
Available below the rubber cover next to the ethernet port.
NWA55AXE:
Available on the board when disassembling the device.

Settings: 115200 8N1

Layout:

<12V> <LAN> GND-RX-TX-VCC

Logic-Level is 3V3. Don't connect VCC to your UART adapter!

Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.

As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.

If the currently installed image is started from Slot A, the device will
flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case
and the device will return to the ZyXEL firmware upon next boot.

If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.

Installation TFTP
-----------------
This installation routine is especially useful in case
 * unknown device password (NWA55AXE lacks reset button)
 * bricked device

Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.

The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.

Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to owrt.bin

 $ atnf owrt.bin
 $ atna 192.168.1.88
 $ atns "192.168.1.66; tftpboot; bootm"

Upon booting, set the booted image to the correct slot:

 $ zyxel-bootconfig /dev/mtd10 get-status
 $ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
 $ zyxel-bootconfig /dev/mtd10 set-active-image 0

Copy the OpenWrt ramboot-factory image to the device using scp.
Write the factory image to NAND and reboot the device.

 $ mtd write ramboot-factory.bin firmware
 $ reboot

07ea71c7b7 ramips: move mt7621_nand driver to files
The patch was rejected by upstream. The mtk_nand driver should be
modified to support the mt7621 flash controller instead. As there is no
newer version to backport, or no upstream version to fix bugs, let's
move the driver to the files dir under the ramips target. This makes it
easier to make changes to the driver while waiting for mt7621 support to
land in mtk_nand.

f579b8538b ath79: add low_mem to tiny image
Devices with SMALL_FLASH enabled have "SQUASHFS_BLOCK_SIZE=1024" in
their config. This significantly increases the cache memory required by
squashfs [0]. This commit enables low_mem leading to a much better
performance because the SQUASHFS_BLOCK_SIZE is reduced to 256.

Example Nanostation M5 (XM):
The image size increases by 128 KiB. However, the memory statisitcs look
much better:

Default tiny build:
------
MemTotal:          26020 kB
MemFree:            5648 kB
MemAvailable:       6112 kB

low_mem enabled:

4b5bd15091 ath79: move ubnt-xm to tiny
ath79 has was bumped to 5.10. With this, as with every kernel change,
the kernel has become larger. However, although the kernel gets bigger,
there are still enough flash resources. But the RAM reaches its capacity
limits. The tiny image comes with fewer kernel flags enabled and
fewer daemons.

b472753d79 mediatek: fix Unifi 6LR network config
When the v1 and v2 variants of the U6LR were introduced, the board
network config was not adapted to the new device names. Due to this, the
wrong network config is applied during initial boot. The resulting
config has lan, wan and a switch, while this device only has a single
ethernet interface without a switch.

Fix this by using a wildcard that matches all the variants.

7c459ac1d5 mac80211: rt2x00: experimental improvements for MT7620 wifi
Serge Vasilugin reports:

To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments with mark (1))
2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see
	https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531
3. Set bbp66 for all chains.
4. US_CYC_CNT init based on Programming guide, default value was 33 (pci),
   set chipset bus clock with fallback to cpu clock/3.
5. Don't overwrite default values for mt7620.
6. Correct some typos.
7. Add support for external LNA:
    a) RF and BBP regs never be corrected for this mode
    b) eLNA is driven the same way as ePA with mt7620's pin PA
	but vendor driver explicitly pin PA to gpio mode (for forrect calibration?)
	so I'm not sure that request for pa_pin in dts-file will be enough

First 5 changes (really 2) improve performance for boards w/o eLNA/ePA.
Changes 7 add support for eLNA

Configuration w/o eLAN/ePA and with eLNA show results
tx/rx (from router point of view) for each stream:
 35-40/30-35 Mbps for HT20
 65-70/60-65 Mbps for HT40

Yes. Max results for 2T2R client is 140-145/135-140
with peaks 160/150, It correspond to mediatek driver results.
Boards with ePA untested.

f54d4ea0bb ramips: add support for Ubiquiti UniFi FlexHD
Hardware
--------

- SoC: MediaTek MT7621AT with 128 MiB RAM and 32 MiB Flash
- Wi-Fi: MediaTek MT7603 (b/g/n, 2x2) and MediaTek MT7615 (ac, 4x4)
- Bluetooth: CSR8811 (internal USB, install kmod-bluetooth)

Installation
------------

1. Connect to the booted device at 192.168.1.20 using username/password
   "ubnt".

2. Update the bootloader environment.

   $ fw_setenv devmode TRUE
   $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
     fdt rm /signature; bootubnt"
   $ fw_setenv bootcmd "run boot_openwrt"

3. Transfer the OpenWrt sysupgrade image to the device using SCP.

4. Check the mtd partition number for bs / kernel0 / kernel1

   $ cat /proc/mtd

5. Set the bootselect flag to boot from kernel0

   $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4

6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1

   $ dd if=openwrt.bin of=/dev/mtdblock6
   $ dd if=openwrt.bin of=/dev/mtdblock7

7. Reboot the device. It should boot into OpenWrt.

420a86436f mediatek: add led count
The LEDs connected to the MCU are so-called smart LEDs and their signal is
daisy-chained. Because of this, the MCU needs to be told how many LEDs are
connected. It also means the LEDs could be individually controlled, if the MCU
has a command for this.

40610c5322 mediatek: add initialization after reset
During GPIO initialization the pin state flips and triggers a reset of
the ledbar MCU. It needs to be moved through an initialization sequence
before working correctly.

26cd0c1ee9 mediatek: add support for reset gpio
Some versions of the ledbar MCU have a reset pin. It needs to be
correctly initialized or we might keep the MCU in reset state.
