    * Fix USB overcurrent issue phyBOARD-MIRA
    * SPI DMA issue. Nor flash should be used without DMA or
      just as boot device
    * Booting from NAND and using SD0 simultaneously fails (phyBOARD-SUBRA)
    * USB Ethernet gadget panics
    * Fix NAND UBIFS corrupted empty space problem in i.MX6 GPMI driver
    * Remove broken USB automount script in poky
    * Increased reliability for ext4 filesystem with option 'data=journal'

Known Issues

    * CAN is not working with 10 kbaud (also didn´t work in previous releases)
    * Ext4 write performance and powercut tolerance tradeoff:
      The root filesystem on eMMC and SD-Cards is mounted with open
      This increases the filesystem reliability in case of power cuts but
      hurts the write performance.  It depends on your application safety
      needs which one you prefer.
      You can change the mount option in the bootloader via the kernel
      parameters. Please note that this option does not impact the read
      performance of the filesystem.
