-Linux Image V2.2 Beta 1 (April 04, 2014)
-- U-Boot:
-  - initial release
-- Linux kernel:
-  - initial release
-- rootfs / oe-core:
-  - initial release
-- sources git.toradex.com tag Apalis_iMX6_LinuxImageV2.2Beta1_20140404
-
-Known Issues:
-- on V1.0 HW connecting an analogue mic to the on module codec resets the codec,
-    so that neither headphone out nor mic in works anymore. Workaround: Have mic
-    connected before boot or change the output source between DAC/LineIn
-- on first boot the resizing process adversely affects system performance for
-    the first few minutes until completed
-- Display resolution can be set for some output configurations, set the U-Boot
-    environment variable vidargs accordingly. Some vidargs_xx variables
-    provided for reference.
-- backlight PWM BKL_PWM (hard-coded to 0 in U-Boot > full brightness on an EDT
-    display)
-- X uses only the fb0 device
-- video decoding leaks resources, after a while it stops working
-- initial rootfs must fit in RAM, i.e. it must not be greater than ~900MB
-- SSH password authentication is disabled by default (see PasswordAuthentication
-    setting in /etc/ssh/sshd_config)
-
-********************************************************************************
-Notes:
-- 115200 baud serial debug console on UART1 (EvalBoard lower X28 resp.
-    X29 depending on JP10/12, X22 on Ixora) without any handshake
-- user account: root with empty password
-- eMMC: partition 1: vfat with kernel, partition 2 ext3 root file system
-- opkg package manager
-- HDMI aka DVI-D: not all pixel clock frequencies allow for HDMI audio
-- Linux host used for update preparation requires proper 32-bit execution
-    environment (e.g. install ia32-libs on 64-bit Ubuntu) and awk (e.g. install
-    gawk on Ubuntu)
-
-Working on latest image:
-- U-Boot boot loader
-  - environment storage in eMMC
-  - Gigabit Ethernet
-  - MMC/SD cards
-  - eMMC flash
-  - RAM size auto detection
-  - serial console debug UART1
-  - Toradex Apalis configuration block handling
-  - USB storage as host on USB host ports
-  - framebuffer support
-- Linux kernel
-  - GPIOlib /sys/class/gpio
-  - PWM LEDs /sys/class/leds/
-  - temperature sensor CPU /sys/devices/virtual/thermal/thermal_zone0/temp
-      board: /sys/devices/soc0/soc.0/2100000.aips-bus/21a4000.i2c/i2c-2/2-0041/stmpe-adc/iio:device0/in_temp8_raw
-  - Gigabit Ethernet (i.MX 6 errata, only 400 Mbps sustainable data rate)
-  - eMMC ext3
-  - serial console debug UART1
-  - UART2, UART3 and UART4
-  - optional RS485
-  - I2C via /dev/i2c-X
-  - 8-bit MMC card mmc1
-  - 4-bit SD card mmc2
-  - framebuffer console
-  - HDMI audio
-  - analogue audio playback and capture, resistive touch
-    - audio noise is high on V1.0 HW, workaround is to set headphone volume
-        to maximum and use the DAC volume
-  - S/PDIF
-  - SPI via /dev/spidev0.0 aka SPI1 and /dev/spidev1.0 aka SPI2
-  - custom Ethernet MAC address
-  - serial number and board revision
-  - USB host port
-  - USB audio driver
-  - USB webcam
-  - USB raw HID device /dev/hidrawX
-  - USB device Ethernet RNDIS, disabled
-  - automatic USB device/host/suspend detection aka full OTG support
-  - analog input via IIO framework
-  - parallel camera interface
-  - CSI2 camera interface
-  - CAN via can0 and can1
-  - PCIe (regular ports and mini-PCIe slot)
-  - SATA (regular port or mSATA slot)
-  - DVFS power management
-  - suspend LP1
-  - watchdog
-- Linux user-space
-  - Firefox browser
-  - Gstreamer playback
-  - OpenGL
-  - LXDE
-  - resize rootfs partition to full eMMC capacity
-  - GPIO config tool
-- Display:
-  - only first output used by X11
-  - dual output on HDMI and LVDS, both in 1920x1080
-  - single output on EDT 7" Display
-  - single output to analog RGB, aka VGA output
-  - resolution setting through modedb string in kernel command line
-
-Not working or not tested:
-- U-Boot boot loader
-  - USB OTG1 support
-- Linux kernel
-  - IrDA
-  - All UART control lines on V1.0 HW
-  - SIM card
-  - HDA audio IF on MXM connector (not possible with i.MX 6)
-  - on V1.0 HW connecting an analogue mic to the on module codec resets the codec,
-    so that neither headphone out nor mic in works anymore. Workaround: Have mic
-    connected before boot or change the output source between DAC/LineIn
-  - I2S / AC97 on MXM connector
-- Linux user-space
-  - Gstreamer encoding (not tested)
-- Display:
-  - on some monitors HDMI EDID does not negotiate correct timings,
-      adding/removing mxc_hdmi.only_cea=1 to the kernel command line may help
-  - more than one framebuffer used as a X screen
-  - backlight PWM on V1.0 HW
-  - DSI output
