The FritzBox 7312 is also known as 1&1 WLAN-MODEM. The device is almost
the same as FB7330, but only one ETH-Port and no USB.

power on a ftp connection need to be established to the FRITZ!Box at

Rename the image and use a compatible string which indicates that only
hardware revision 2 and higher is supported.
It allows to use the wireless LED, as HWRev 1 uses GPIO#39 for the
wireless LED and starting with HWRev 2 GPIO#35 is used for the wireless
LED and GPIO#39 for IFX_GPIO_MODULE_EXTPHY_MDIO.
The HWREV can be checked by connecting to the fritzbox right after power
on via ftp:
ftp> quote GETENV HWSubRevision
Within the same HW revision 5 of the Fritz!Box 3370 different NAND flash
chips are used. Usually it isn't a big deal but depending on the used
NAND flash chip, the ECC calculation is done different (and incompatible
of course).
Boards with a Micron MT29F1G08ABADA NAND flash chip are using the NAND
chip to calculate the ECC (on-die). Boards with a Hynix HY27UF081G2M NAND
flash chip are doing the ECC calculation in software.
Supporting both with a single DTS isn't possible. It might be possible
to add a patch selecting the ECC mode dynamicaly based on the found NAND
flash chip. But such a patch has no chance to get accepted upstream and
most likely need to be touched with every kernel update.
Instead two images are created. One for Micron NAND flash chip and one
for Hynix NAND flash chip. So far no pattern is known to identify the
used flash chip without opening the box.
Add the power off GPIO. At least EVA version 2186 sets/keeps the GPIO as
input, which will cause a reboot 30sec after power on. For boards with
EVA version 2186 the installation is tricky as it has to be finished
within the 30sec time frame.
The EVA version can be checked by connecting to the fritzbox right after
power on via ftp:
ftp> quote GETENV urlader-version
The ath9k eeprom/caldata is at a different and offset and stored in
reverse order (from the last byte to the beginning) on the flash.
Reverse the bits to bring the data into the format expected by the
ath9k driver.
Since the ath9k eeprom is stored in reverse order on flash, we can not
use the mac address from the on flash eeprom. Get the MAC address from
the tffs instead.
Within the same HW revision 5 of the Fritz!Box 3370 both version of the
vr9 SoC are used. During preparation of kernel 4.14 support, all
devicetree source files were changed to load the vr9 v1.1 and vr9 v1.2
gphy firmware, which fixed the embedded phys for boards using the
version 1.2 of the vr9 SoC.
While at it, add a trigger to make use of the LAN LED. Setup the
build-in switch and add a hint for LuCI two show the ports in order
matching the labels on the case
Add support for the second USB port and provide the volatage GPIOs. Use
GPIO#21 as PCIe reset pin. The lan led is connected to GPIO#38.
Name the rootfs partition ubi and remove the mtd/rootfs related kernel
bootargs to use the OpenWrt autoprobing based on the partition name.
Enable sysupgrade support to allow an upgrade from a running system.
Since sysupgrade wasn't supported till now, drop image build code which
was added to allow a sysupgrade from earlier OpenWrt versions.
Build images that allow an (initial) installation via EVA bootloader.
To install OpenWrt via Eva bootloader, within the first seconds after

Use the first compatible string as board name in userspace. Add the new
board name as well as the former used board name to the image metadata
to keep compatibilty with already deployed installations.
Don't add the former used boardname for boards which exists only in
master or evaluation boards.

It has been shown that the Fritz boxes have the correct mac address set
in the wireless calibration data/eeeprom. Use this mac address as base
for the ethernet and xdsl interface increment/decrement the address to
match the values stored in the tffs.

The firmware hotplug script tries to read the mac address from a
partition with the name "uboot-env" which does not exist (instead it's
name is uboot_env). This broke calculation of the new checksum (after
patching the mac address) which resulted in ath9k refusing to use the
EEPROM data.
The original error reported by ath9k was:
PCI: Enabling device 0000:00:0e.0 (0000 -> 0002)
ath: phy0: Bad EEPROM checksum 0x2523
ath: phy0: Unable to initialize hardware; initialization status: -22
ath9k 0000:00:0e.0: Failed to initialize device

Add an extra function to patch the mac and fixup the checksum
afterwards. Calculate the checksum position automatically. The offset
to the mac address is the same for all checksum protected EEPROMs.
No EEPROM requires a byte swapped mac address. The mac byte swap code
was required due to an bug in the script that is now fixed.

The EEPROM data in the flash of the ARV7518PW, ARV8539PW22,
BTHOMEHUBV2B and BTHOMEHUBV3A is stored byte-swapped (swab16), meaning
that for example the ath9k base_eep_header fields "version" (high and
low byte), "opCapFlags" and "eepMisc" are swapped (the latter ones are
just 1 byte wide, thus their position is swapped).
The old "ath,eep-endian" property enabled the corresponding swapping
logic in the ath9k driver (swab16 in ath9k_hw_nvram_swap_data, which is
based on the magic bytes in the EEPROM data which have nothing to do
with the calibration data - thus this logic should not be used
anymore).
Since we have switched to the upstream ath9k devicetree bindings there
is no binding anymore which enables swab16 in ath9k (as this logic is
not recommended anymore as explained above), leading to ath9k
initialization errors:
ath: phy0: Bad EEPROM VER 0x0001 or REV 0x00e0
(this shows that the version field is swapped, expected values are VER
0x000E and REV 0x0001)
Swapping the ath9k calibration data when extracting it from the flash
fixes the devices listed above (all other devices do not require
additional swapping, since the position of the fields is already as
expected by ath9k). This allows ath9k to read the version correctly
again, as well as the more important "eepmisc" field (which is used for
determining whether the data inside the EEPROM is Big or Little Endian
which is required to parse the EEPROM contents correctly).

This way the on nand bad block table is preserved and used. Add support
for nand OOB ECC checksums as well. It should fix all reported ubi
errors, which were all related to bad nand blocks and a purged on nand
bad block table.
The existing ubi partition will be reused, which eliminates the need
to touch the caldata during initial install. The BT u-boot has support
for loading a kernel from an ubi volume. It isn't necessary any longer
to replace the BT u-boot with a custom compiled one to use LEDE.
It is required to restore the BT Firmware and install LEDE from scratch
to switch to the new partition layout.
An image for restoring the BT firmware and installing LEDE is provided
at https://github.com/mkresin/lede/releases.

This moves the extraction of the eeprom/calibration data to a hotplug
firmware script. Additionally it modifies all .dts to configure ath9k
directly from within the .dts.
The owl-loader approach enables support on devices with exotic eeprom
data locations (such as unaligned positions on the flash or data
inside an UBI volume).
