+*************************************************
+Release Notes: Linux Image V2.x for Colibri VF50
+*************************************************
+
+Contents:
+- U-Boot 2011.12 boot loader
+- Linux 3.0.15 kernel, based on Freescale TWR-VF65GS10 Timesys LinuxLink 2013-07-29
+- OpenEmbedded oe-core 2013.06 based root file system, using LXDE desktop environment
+
+********************************************************************************
+Linux Image V2.1 Beta 1 (October 22, 2013)
+- U-Boot:
+ - Fix long standing boot hang issue introduced by Freescale's Vybrid 1.1 silicon.
+ - Fix possible uninitialised array member issue in serial number to
+ hexadecimal coded decimal conversion routine (e.g. as used for
+ /proc/cpuinfo in Linux).
+ - Migrate default NAND vs. SD card boot configuration (in-line with Colibri T20)
+ - Integrate config block handling
+ - Increase the available space for the U-Boot binary to half a megabyte by booting from gfxRAM rather than sysRAM0.
+ - Initial support based off Timesys' implementation for Freescale's Vybrid Tower System TWR-VF65GS10:
+ - New machine ID.
+ - Default UART_A on SCI0.
+ - ESDHC2 only.
+ - 8-bit NAND.
+ - No quad SPI.
+ - FEC1 only.
+ - Enabled command line editing.
+ - PLL5 based RMII clocking (e.g. no external crystal).
+ - UART_A, UART_B and UART_C I/O muxing.
+- Linux kernel:
+ - Hackish USBH_PEN implementation.
+ - Setup memory if mem= is not passed to kernel.
+ - Enable RTS/CTS on UART_A aka UART0 and UART_B aka UART2.
+ - Integrate backlight using both BL_ON GPIO and PWM<A>.
+ - Re-worked IOMUX pin muxing.
+ - 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.
+ - Decrease DMA zone size configuration.
+ - Enable tmpfs POSIX ACL configuration.
+ - Re-enable L2 cache kernel configuration as it is now only enabled if actually present on chip.
+ - Implement resistive touch screen driver using ADCs and GPIOs.
+ - Add Eon Silicon Solutions manufacturer ID and integrate mxc_nand platform data handling.
+ - Disable NAND controller software ECC in order to use hardware ECC.
+ - Enable ADC driver as well as debugfs file system.
+ - Fix DCU clock rounding, set DCU clock to 150.7 MHz, increase display pin drive strength and
+ configure DCU for VESA VGA with a 30 MHz pixel clock
+ - Enable CPU idle, NEON, ASRC and printk time.
+ - Initial support based off Timesys' implementation for Freescale's Vybrid Tower System TWR-VF65GS10:
+ - New machine ID.
+ - FEC1 only.
+ - ESDHC2 only with card detect interrupt.
+ - PLL5 based RMII clocking (e.g. no external crystal).
+ - VESA VGA display timing (tested with 5.7" EDT ET057090DHU).
+ - Default UART_A on SCI0.
+ - UART_A and UART_C I/O muxing.
+ - I2C real time clock on carrier board.
+ - Early boot console support.
+ - 8-bit NAND.
+- rootfs / oe-core:
+ - OpenEmbedded: layers from dylan
+ xserver version 1.14
+ gtk+ 2.24.15
+ midori 0.5.0
+ - NEON and hard float enabled build
+ - feed-config: use the new feed armv7ahf-vfp-neon
+ - evdev: backport V2.8.1 from dora to get a fix for multitouch events
+ - browser: use midori
+ - burnflash: script for configblock generation
+ - systemd-journald: limit journal size
+- sources git.toradex.com linux/u-boot branches colibri_vf tag Colibri_VF50_LinuxImageV2.1Beta1_20131022
+
+Known Issues:
+- LVDS aka TFTLCD resolution hard-coded in kernel to VESA VGA resolution.
+
+********************************************************************************

+**************************************
+NAND Boot: Colibri VF50 V1.0a (Sample)
+**************************************
+
+If the boot loader in NAND got corrupted SD card boot as described further down can be used as a means of recovery.
+
+Initial Preparation:
+- download and extract Colibri_VF50_LinuxImageVx.yz.tar.bz2 package with root permissions
+- use any VFAT formatted SD resp. uSD card with at least 100 MB of free space
+- optionally format the SD resp. uSD card using the format_sd.sh script (warning everything will be erased)
+- run update.sh script with optional -o argument pointing to mount point of above mentioned card
+
+Flash NAND:
+- EvalBoard V3.1a
+ - 115200 baud serial debug console on UART0 aka FFUART (lower X25 resp. X27 depending on JP17/19) without any handshake
+ - insert above prepared SD card into SD card/MMC SDIO-socket (X15)
+- Iris V1.1a
+ - 115200 baud serial debug console on UART0 aka FFUART (X13) without any handshake
+ - insert above prepared uSD card into uSD card holder (X10)
+ - apply power or reset
+ - hit any key to stop auto booting
+ - use 'mmc part 0 ; fatload mmc 0:1 $loadaddr flash_mmc.img ;source' commands
+ - use 'run update' command
+
+Boot from NAND:
+- EvalBoard V3.1a or Iris V1.1a
+- 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

+- format and flash SD resp. uSD card using format_sd.sh script giving -d argument pointing to
+ device file of SD card and -f argument (warning everything will be erased)
