********************************************************************************
+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.
+ - Add entry for fusion touchscreen driver to xorg.conf.
+ - Add fstrim from util-linux.
+ - Add kernel module for fusion touch screens (see
+ http://developer.toradex.com/knowledge-base/capacitive-multi-touch-display-(linux)).
+ - burnflash: Account for fs overhead and many files.
+- sources git.toradex.com tag Colibri_T30_LinuxImageV2.1Beta2_20140206
+
+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
