-********************************************************************************
-Linux Image V2.1 Beta 2 (February 6, 2014)
-- U-Boot:
-  - Add more UART configurations to the device trees allowing easy switching of
-    the console UART port by changing the UART base address of the console node
-    within the device tree.
-  - Fix EHCI periodic list handling.
-  - Add default VESA VGA vidargs for our now modedb enabled kernel. This allows
-    easy specifying an alternate parallel RGB resolution.
-  - Fix usbboot option to be more in-line with how we do optional MMC/SD card
-    boot on Colibri VF50/VF61. Loads the uimage kernel from the first partition
-    being formatted as VFAT and instructs the kernel to mount the second
-    partition formatted as ext3 as root file system.
-- Linux kernel:
-  - Use TPS6591X IRQ base define to calculate correct IRQ number.
-  - Remove vdd_hdmi_con regulator from dc1 since we don't have a dedicated
-    regulator for this connector on our baseboards.
-  - Fix SATA suspend/resume by adding avdd_plle regulator.
-  - Fix HDMI suspend/resume by avoiding division by zero oops.
-  - Add GPIO keyboard configuration.

-    http://developer.toradex.com/knowledge-base/framebuffer-(linux) and
-    http://developer.toradex.com/knowledge-base/x-server-(linux)).
-  - Check null pointers for sysfs calls.
-  - Hack to avoid 24 Hz mode in X resulting in no display at all. This has been
-    encountered using e.g. a Samsung SyncMaster F2380 if connected by HDMI.
-  - Add kernel parameters to change RGB clock polarity.
-  - Re-work Fusion multi-touch touchscreen driver.
-  - Before updating modes on HDMI hotplug, check if framebuffer is registered
-    at all. This allows to disable framebuffers completely.
-- rootfs / oe-core:
-  - Fix build and texinfo errors for stress.
-  - Add sections for both monitor outputs to xorg.conf. Add example
-    configuration to disable an output as well as select preferred mode.
-  - Add entry for fusion touchscreen driver to xorg.conf.
-  - Add fstrim from util-linux.
-  - Add kernel module for fusion touch screens (see

-Known Issues:
-- 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
-- certain low-speed USB devices might not get detected
-- on first boot the resizing process adversely affects system performance for 
-    the first few minutes until completed

-- U-Boot:
-  - Fix possible uninitialised array member issue in serial number to
-      hexadecimal coded decimal conversion routine (e.g. as used for
-      /proc/cpuinfo in Linux).
-  - Fix Linux USB OTG1 behaviour by not enabling USBO1_EN during
-      boot as USB host functionality on OTG1 port is anyway broken under U-Boot.

-  - Support default watchdog API (see
-      http://developer.toradex.com/knowledge-base/watchdog-(linux)).
-  - Disable magic SysRq key configuration as this is not only a potential
-    security thread but can cause serious trouble if for some reason UART
-    pins are left floating and therefore cause unexpected break conditions.
-  - HDMI: Retry EDID reads up to 4 times until failing.
-
-- rootfs / oe-core:
-  - OpenEmbedded: layers updated to dylan
-      xserver update to version 1.14

-    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

-  - use a generic approach to get the MTD partitions to ease changes to the partition layout
-    (Initial partition table parsing courtesy of Mitja Špes from LXNAV)
-  - added command 'enterrcm' which puts the CPU into recovery mode
-- updated kernel
-  - fix to correctly reset Ethernet chip
-  - added one wire platform data (conditional, CONFIG_W1_MASTER_TEGRA must be enabled)
-- rootfs
-  - no changes to V1.1
-
-********************************************************************************
-Linux Image V1.1 (October 31, 2012)
-- none, this version is identical to the previous beta version V1.1 Beta 2
-
-********************************************************************************
-Linux Image V1.1 Beta 2 (September 26, 2012)
-- updated BCT
-  - Colibri T20 V1.1c unified with BCT for other module versions
-- updated U-Boot
-  - SPI fix, U-Boot defined one pin to be GPIO which prevented SPI from working
-  - backlight GPIO switched on upon boot
-  - new environment variable 'setup' which makes e.g. carveout memory easily adjustable
-- updated kernel
-  - backlight PWM clock changed from 500kHz to 200Hz
-  - PWM B, PWM C, PWM D now accessible from userspace via /sys/class/leds
-- updated rootfs
-  - LXDM fix, interactive login also works now, not only autologin

-Linux Image V2.0 Alpha 2 (October 19, 2012)
-- update to L4T R16, !!!THIS REQUIRED TO CHANGE THE CALLING CONVENTION TO HARD
-  FLOAT!!!

-  comments with timings for other resolutions provided
-- some gstreamer plugins, notably mp3decoding, h264encoding not working
-- some windows have garbled titlebar, e.g. lxterminal
-- lxappearance is segfaulting upon start
-- USB OTG port, not working
-- SD card boot copies only 4 MB from kernel (see further below for workaround)
-
-Calling Convention hard float:
-The way floats are passed in subroutine calls can be either in processor
-registers or in the floating point coprocessor registers.
-The processor register approach is used when gcc is called with
--mfloat-abi=softfp or -mfloat-abi=soft
-The FPU register approach is used when gcc is called with -mfloat-abi=hard
-These two methods are not compatible with each other, all programs and libraries
-must be compiled either with softfp/soft or with hard.
-Thus all code used with Alpha2 must be recompiled. If you start a program which
-uses soft calling convention you will get a 'No such file or directory' error,
-despite that the file exists and has executable permissions.

-Known Issues:
-- 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
-- Ethernet aka TFTP update requires manual splitting of the root.ext3 file
-    which can be taken care of by the -c argument of our update.sh script.
-- LP1 suspend might fail due to pending USB interrupts
-- LP1 suspend might hang due to display controller issue

-Note:
-- mount point names changed from /media/<block device name> to /media<label>
-- no SD boot integration yet but copying cbootimage to beginning of SD card

-
-Known Issues:
-- default vidargs includes 'fbcon=map:1' which causes the framebuffer console
-    only ever to be visible on a DVI-D aka HDMI screen should there any such
-    actually be connected. Just removing this either from within the U-Boot
-    console as follows:
-      setenv vidargs video=tegrafb0:640x480-16@60; saveenv
-    or from within Linux:
-      fw_setenv vidargs video=tegrafb0:640x480-16@60
-    fixes this by defaulting back to showing it on DVI-A aka VGA resp. parallel
-    RGB.
-- 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

-Linux Image V2.1 Beta 2 (February 6, 2014)
-- U-Boot:
-  - Add more UART configurations to the device trees allowing easy switching of
-    the console UART port by changing the UART base address of the console node
-    within the device tree.
-  - Fix EHCI periodic list handling.
-  - Add default VESA VGA vidargs for our now modedb enabled kernel. This allows
-    easy specifying an alternate parallel RGB resolution.
-  - Fix usbboot option to be more in-line with how we do optional MMC/SD card
-    boot on Colibri VF50/VF61. Loads the uimage kernel from the first partition
-    being formatted as VFAT and instructs the kernel to mount the second
-    partition formatted as ext3 as root file system.
-- Linux kernel:
-  - Use TPS6591X IRQ base define to calculate correct IRQ number.
-  - Remove vdd_hdmi_con regulator from dc1 since we don't have a dedicated
-    regulator for this connector on our baseboards.
-  - Fix HDMI suspend/resume by avoiding division by zero oops.
-  - Don't register KEY_BACK for wakeup.
-  - Add STMPE ADC driver using IIO framework
-    (see http://developer.toradex.com/knowledge-base/adc-(linux)).
-  - Use modedb to specify framebuffer resolution (see
-    http://developer.toradex.com/knowledge-base/framebuffer-(linux) and
-    http://developer.toradex.com/knowledge-base/x-server-(linux)).
-  - Check null pointers for sysfs calls.
-  - Hack to avoid 24 Hz mode in X resulting in no display at all. This has been
-    encountered using e.g. a Samsung SyncMaster F2380 if connected by HDMI.
-  - Add kernel parameters to change RGB clock polarity.
-  - Re-work Fusion multi-touch touchscreen driver.
-  - Before updating modes on HDMI hotplug, check if framebuffer is registered
-    at all. This allows to disable framebuffers completely.
-- rootfs / oe-core:
-  - Fix build and texinfo errors for stress.
-  - Add sections for both monitor outputs to xorg.conf. Add example
-    configuration to disable an output as well as select preferred mode.

-Known Issues:
-- gstreamer freezes when generating its initial database on some modules:
-    (gst-plugin-scanner:683): GLib-GObject-WARNING **: cannot register existing
-    type 'GstImxCompositorPad'
-    The following gets you around this:
-      mv /usr/lib/libgstimxcompositor.so.0.12.0 /usr/lib/libgstimxcompositor.so.0.12.0.orig
-      gst-inspect-1.0
-      mv /usr/lib/libgstimxcompositor.so.0.12.0.orig /usr/lib/libgstimxcompositor.so.0.12.0
-    Alternative one can uninstall libgstimxcompositor0
-      opkg remove --force-depends libgstimxcompositor0
-- On the Colibri iMX6DL the RAM configuration is not patched correctly, thus

-Linux Image V2.6.1 Beta 1 (September 29, 2016)
-
-- U-Boot boot loader:
-  - backport patches needed if compiling with GCC 6
-  - autodetect SoC and set soc environment variable accordingly
-  - set soc environment variable also in recovery mode (#20568)
-  - patch device tree with serial number, product id and revision properties to
-    make that information available in Linux
-  - configure PMIC for suspend/sleep modes
-  - fix writing of first firmware copy
-  - print warning about upcoming NAND change:
-	WARNING: This module uses an early tapeout/stepping
-	of the i.MX 7 SoC which suffers a NAND flash issue
-	requiring a software workaround. This U-Boot version
-	still implements this workaround, but future U-Boot
-	versions provided by Toradex will not use the
-	workaround anymore. You must use a newer Colibri
-	iMX7 (V1.1B or later) to use future software
-	versions. For evaluation and testing purposes it will
-	be possible to keep the current U-Boot and only
-	update the kernel and root filesystem.
-- Linux kernel:
-  - merge changes from latest NXP release 4.1.15_1.2.0_ga
-  - backport patches needed if compiling with GCC 6
-  - enable audio clock earlier (and pinmux MCLK) to properly fix initialization
-  - enable USB power (USBH_PEN) also on Colibri iMX7 Solo (required for Aster/
-    Orchid/Viola carrier boards)
-  - honour native-mode in display timings node
-  - add SODIMM pin 45 as wake-up key
-  - control BL_ON (using the PWM backlight drivers enable-gpios property)
-  - add PWM polarity support (#18164)
-  - disable internal RTC on Colibri iMX7 Solo (currently not functioning)
-  - enable USB OTG device/host detection on USBC (#19050)
-  - improve pinmuxing (disable conflicting pinmux on multiplexed pins and fix
-    conflicting pinmux on pins which are pulled on carrier board)
-  - keep 240MHz system clock on which allows to start the Cortex-M4 core via
-    JTAG
-  - synchronize defconfig (#19484)
-- Linux user-space:
-  - none
-- OpenEmbedded build system:
-  - split meta-toradex into BSP layers meta-toradex-bsp-common and
-    meta-toradex-nxp as well as the software layer meta-toradex-demos
-  - rename the parent directory from stuff to layers
-  - mv from build/out*/deploy to deploy
-  - rename TMPDIR from out to tmp
-  - deploy qt5 tools into the sdk as part of optional angstrom-qt5-x11-image.bb

-
-Note:
-- A new boot schema using static UBI volumes has been introduced. Therefore
-  downgrading is not directly possible. To downgrade a module, the UBI
-  partition needs to be cleared manually using "nand erase.part ubi".
