 ********************************************************************************
+Linux Image V2.5 Beta 2 (November 6, 2015)
+- U-Boot boot loader:
+  - add return code for cfgblock commands which allows scripting
+  - increase TFTP blocksize for better performance
+  - fix setup of I2C3
+  - enable eMMC boot support commands (e.g. /dev/mmcblk0boot0)
+  - enabled zero bootdelay check (allows entering U-Boot when bootdelay is 0)
+  - move environment to the end of the eMMC boot area before the config block
+  - enable crc32 verify support
+- Linux kernel:
+  - migrate to Linux 3.14.28 kernel, based on Freescale's BSP release imx_3.14.28_1.0.0_ga
+  - automatic USB device/host detection using USBC_DET pin
+  - changed Fusion multi touch event reporting to adhere to multitouch slot
+- Linux user-space:
+  - updated to latest Angstrom 2015.06/OpenEmbedded fido:
+    - glibc 2.22
+    - systemd 219
+    - Xorg 1.16.1
+  - glibc: force memcpy_arm to improve memcpy performance
+  - fw_printenv/setenv: follow U-Boot environment move
+  - updated Vivante binary graphics/multimedia drivers (some gstreamer plugins changed their names)
+  - fix USB RNDIS operation (still racy due to networkd bug)
+- OpenEmbedded build system:
+  - local.conf: add Toradex source mirror as pre-mirror
+- Update scripts:
+  - Ethernet aka TFTP update: provide option to split rootfs output file
+  - update.sh: delete intermediate files after use
+  - improved update.sh to use module type specific folders allowing update of
+    different modules with just one update media
+
+- sources git.toradex.com tag Apalis_iMX6_LinuxImageV2.5Beta2_20151106

+  - repository u-boot-toradex branch 2015.04-toradex
+
+Known Issues:
+- USB RNDIS is racy due to networkd bug
+- some USB Thumb drivers don't work well in U-Boot
+- 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.
+- X uses only the fb0 device
+- 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.

-**************************************************************************
-eMMC Boot: Colibri iMX6S 256MB V1.0a (Sample), iMX6DL 512MB V1.0a (Sample)
-**************************************************************************
-
-Initial Preparation:
-- download and extract Colibri_iMX6_LinuxImageVx.yz.tar.bz2 package with root
-    permissions
-- use any VFAT formatted SD resp. micro SD card with at least 1000 MB of free
-    space
-- run update.sh script with -o argument pointing to mount point of
-    above mentioned card
-
-Flash eMMC:
-- EvalBoard V3.1a
-  - depending on JP17/19 connect serial debug console to UARTA aka FFUART
-      (lower X25) using null modem RS-232 cable resp. X27 using a regular USB
-      cable
-  - insert above prepared SD card into SD/MMC socket (X15)
-- Iris V1.1a
-  - connect serial debug console to UARTA aka FFUART X13 using null modem RS-232 cable and a
-      10 pin IDC to 9 pin D-sub male connector. (DTK or Intel standard)
-  - insert above prepared micro SD card into micro SD card socket (X10)
-- Boot to U-Boot prompt and start the update:
-  - apply power or reset
-  - hit any key to stop auto booting
-  - use 'run setupdate' U-Boot command and then
-  - use 'run update' U-Boot command
-- Update a single component
-  - U-Boot
-    use 'run setupdate' and then 'run update_uboot'
-    use 'patch_ddr_size' to set the memory configuration depending on module
-      type. (i.e the Colibri iMX6 DL will use only half of the available RAM)
-  - Kernel or Linux Device Tree
-    use 'run setupdate' and then 'run update_kernel' or 'run update_fdt' respectively
-
-Boot from eMMC:
-- above given update command should automatically perform a soft re-boot upon successful completion
-- optionally power cycle
-- upon first boot post-install scripts are run which takes around 2 minutes,
-    please be patient
-
-If the boot loader on the module got corrupted this recovers it by loading U-Boot
-  over USB into the module's RAM and executing it there:
-- EvalBoard V3.1a
-  - connect USB B (X29) or USB micro A/B (X30) to development workstation using
-      regular or micro USB cable
-  - the jumper JP2 must be open
-  - connect serial debug console as stated above
-- Iris V1.1a
-  - connect USB micro A/B (X12) to development workstation using regular micro USB
-      cable
-  - connect serial debug console as stated above
-- make sure that the carrier board supports USB high speed
-  - Iris & EvalBoard V3.1a OK, for other carrier boards see
-      http://developer.toradex.com/knowledge-base/usb-2.0-high-speed-%28480mbps%29
-(see Colibri iMX6 Datasheet for recovery mode)
-- have the module in recovery mode and load U-Boot over USB to the module's RAM:
-  - lsusb should show a 15a2:0054 Freescale Semiconductor, Inc. device if
-      the module is in recovery mode
-  - run ./update.sh -d
-  - stop at the U-Boot prompt and begin the update as stated above
