Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on". Vendor firmware (looks like
an illegal OpenWrt fork) won't accept any serial input unless
"uart_en" is set to "1". Tricks to force u-boot to use default
environment do not help as it's restricted in the same way.
With bootloader unlocked the easiest way would be to TFTP the
sysupgrade image or to sysupgrade after loading an initramfs one.
For porting the flash contents were changed externally with an SPI
programmer (after lifting Vcc flash IC pin away from the PCB).

ipq40xx: generic-level patch replaces same-source patches-4.19/
082-v4.20-mtd-spinand-winbond-Add-support-for-W25N01GV.patch
The SPI-NAND framework from Linux uses common driver code that is then
"tuned" by a tiny struct of chip-specific data that describes
available commands, timing, and layout (data and OOB data). Several
manufacturers and chips have been added since 4.19, several of which
are used in devices already supported by OpenWrt (typically with no or
"legacy" access to their NAND memory). This commit catches up the
supported-chip definitions through Linux 5.2-rc6 and linux/next.
The driver is only compiled for platforms with CONFIG_MTD_SPI_NAND=y.
This presently includes ipq40xx and pistachio, with the addition of
ath79-nand in these commits (and not ath79-generic or ath79-tiny).

Installation
------------
1. Grab the uboot for the Device from the 'u-boot-fritz1200'
subdirectory. Place it in the same directory as the 'eva_ramboot.py'
script. It is located in the 'scripts/flashing' subdirectory of the
OpenWRT tree.
2. Assign yourself the IP address 192.168.178.10/24. Connect your
Computer to one of the boxes LAN ports.
3. Connect Power to the Box. As soon as the LAN port of your computer
shows link, load the U-Boot to the box using following command.
> ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz1200.bin
4. The U-Boot will now start. Now assign yourself the IP address
192.168.1.70/24. Copy the OpenWRT initramfs (!) image to a TFTP
server root directory and rename it to 'FRITZ1200.bin'.
5. The Box will now boot OpenWRT from RAM. This can take up to two
minutes.
6. Copy the U-Boot and the OpenWRT sysupgrade (!) image to the Box using
scp. SSH into the Box and first write the Bootloader to both previous
kernel partitions.
> mtd write /path/to/uboot-fritz1200.bin uboot0
> mtd write /path/to/uboot-fritz1200.bin uboot1
7. Remove the AVM filesystem partitions to make room for our kernel +
rootfs + overlayfs.
> ubirmvol /dev/ubi0 --name=avm_filesys_0

Based on stock firmware tests, both LAN and WAN ports use the
MAC address from 0x28 on factory partition.
In OpenWrt, this one is already set in DTS. This patch removes the
local bit set in 02_network previously, and adjusts LAN/WAN
addresses as on stock firmware.
Note that in tests we found a MAC address in 0x2e that is the one
in 0x28 plus 1. Since stock firmware does not use it though, we
do not use it either.
Thanks to Chih-Wei Chen for testing this on his device.

This commit adds support for the 32MB storage/512MB RAM version of the U4019
IPQ4019-based board from Unielec. The board has the following specifications:
* Qualcomm IPQ4019 (running at 717MHz)
* 512MB DDR3 RAM (optional 256MB/1GB)
* 32MB SPI NOR (optional 8/16MB or NAND)
* Five gigabit ports (Qualcomm QCA8075)
* 1x 2.4 GHz wifi (QCA4019 hw1.0)
* 1x 5 Ghz wifi (QCA4019 hw1.0)
* 1x mini-PCIe slot (only USB-pins connected)
* 1x SIM slot (mini-SIM)
* 1x USB2.0 port
* 1x button
* 1x controllable LED
* 1x micro SD-card reader
Working:
* Ethernet
* Wifi
* USB-port
* mini-PCIe slot + SIM slot
* Button
* Sysupgrade
Not working:
* SD card slot (no upstream support)
Installation instructions:
In order to install OpenWRT on the U4019, you need to go via the
initramfs-image. The installation steps are as follows:
* Connect to board via serial (header exposed and clearly marked).
* Interrupt bootloader by pressing a button.
* Copy the initramfs-image to your tftp folder, call the file C0A80079.img.
* Give the network interface connected to the U4019 the address
192.168.0.156/24.
* Start your tftp-server and run tftpboot on the board.
* Run bootm when the file has been transferred, to boot OpenWRT.
* Once OpenWRT has booted, copy the sysupgrade-image to the device and run
sysupgrade to install OpenWRT on the U4019.
Notes:
- Since IPQ4019 has been moved to 4.19, I have not added support for kernel
4.14.
- There is a bug with hardware encryption on IPQ4019, causing poor performance
with TCP and ipsec (see for example FS#2355). In order to improve performance,
I have disabled hardware encryption in the DTS. We can enable hw. enc. once/if
bug is fixed.
- In order for Ethernet to work, the phy has to be reset by setting gpio 47
low/high. Adding support for phy reset via gpio required patching the
mdio-driver, and the code added comes from the vendor driver. I do not know if
patching the driver is an acceptable approach or not.

This patch contains updated driver for Atheros NAND Flash Controller
written originally by Gabor Juhos for ar71xx (aka 'ar934x-nfc').
ath79 version has adapted to work with kernel 4.19 and Device Tree.
It has also been renamed to 'ar934x-nand' to avoid confusion with
Near-Field Communication technology.
Controller is present on Atheros AR934x SoCs and required for accessing
internal flash storage on routers like Netgear WNDR4300.
This port preserves all NAND programming code while moving platform
configuration to Device Tree and replacing some kernel functions marked
for retirement by 4.19.
Suitable definition is included in 'ar934x.dtsi' ('nand@1b000200' section).
Most important changes to ar71xx version are:
* old kernel sections of code removed
* 'bool swap_dma' provided by platform data is now set by boolean DT
property 'qca,nand-swap-dma'
* board-supplied (mach-*.c code) platform data removed - its elements
become either unused, redundant or replaced by DT methods (like reset)
* IRQ is reserved by devm_request_irq() so free_irq() is not needed anymore
* calls to deprecated nand_scan_ident() + nand_scan_tail() function pair
replaced by using recommended nand_scan() with attach_chip() callback
* ECC is set to hardware by default, can be overriden by standard DT
'nand-ecc-*' properties (software Hamming or BCH are other options)
This driver has been successfully tested on Netgear WNDR4300 running
experimental ath79 OpenWrt master branch.

For this configuration, the use of spin_lock() is not sufficient
