Supported frequencies of all ipq40xx chips are 48, 200, 500 and 716.8 MHz.
Previous 666MHz setting was most likely related to instability of early
chips/boards made before mass production.

This patch adds support for AVM FRITZ!Box 4040.
hardware highlights:
SOC: IPQ4018 / QCA Dakota
CPU: Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7
DRAM: 256 MiB Nanya NT5CC128M16IP
FLASH: 32 MiB MXIC MX25L25635FMI
ETH: Qualcomm Atheros QCA8075 Gigabit Switch (4 x LAN, 1 x WAN)
USB: 1 x 3.0 (via Synopsys DesignWare DWC3 controller in the SoC)
1 x 2.0 (via Synopsys DesignWare DWC3 controller in the SoC)
WLAN1: Qualcomm Atheros QCA4018 2.4GHz 802.11bgn 2:2x2
WLAN2: Qualcomm Atheros QCA4018 5GHz 802.11a/n/ac 2:2x2
INPUT: one WLAN and one WPS button
LEDS: Power, WAN/Internet, WIFI, INFO (red and amber) and LAN.
Serial:
WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
The Serial setting is 115200-8-N-1. The SoC's serial port is right
next to the MXIC FLASH chip. The board has a unpopulated 1x4 0.1"
header for it. Use a multimeter to figure out the pinout!
This board currently needs an additional u-boot image in order to boot
properly. Booting with EVA isn't possible ATM.
Install Procedure:
0. It's highly recommended to connect to the serial port.
The serial settings are listed above.
1. install a u-boot image for AVM Fritz!Box 4040
(see <https://github.com/chunkeey/FritzBox-4040-UBOOT/releases> and
<https://github.com/chunkeey/FritzBox-4040-UBOOT/blob/master/upload-to-f4040.sh>)
2. upload the initramfs.itb image via tftp (u-boot listens to
192.168.1.1 - use binary transfer mode!)
3. connect to the FB4040 and use sysupgrade sysupgrade.bin
to install the image.
Works:
- Switch and Ethernet (99%)
- Buttons (WLAN, WPS)
- FLASH (1 x 32MiB NOR Chip)
- WLAN2G and WLAN5G
- CPUFREQ scaling
- PRNG
- serial
- Crypto Accelerator
- sysupgrade (Read the flash instructions to avoid bricking)
- full LEDE Install (Read the flash instructions to avoid bricking)
- LEDs (Power, WAN, Info (red and amber), LAN)
The LEDs are connected to the QCA8075 LED ports.
The AR40xx driver contains a gpio-controller to
handle these special "GPIOs".
- USB Both 3.0 and 2.0 ports
- many packages from other ARMv7 boards
(This does include the RaspberryPi Model 2!)
- ...
Not planned:
- WAN<->LAN short-cut
- Qualcomm Secure Execution Environment
- ...
