   1. Welcome
   2. I'm going to dump a lot of information on you, don't worry you do not need to remember it all :)
   3. Quickly explain of different Axx models
   4. A10 Datasheet Block diagram (page 12), give a quick overview of the A10
2. A10 SoC dtsi file (example)
   1. sun4i-a10.dtsi
   2. For a list of addresses see the A10 user manual, section 3.2 "Memory mapping", and 11.2 "Interrupt Source"
   3. For clock tree info see: A10 Datasheet Clock tree diagram (pages 51 - 54)
3. dts file example for a simple board
   1. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/sun4i-a10-mini-xplus.dts | sun4i-a10-mini-xplus.dts]
4. Hands on 1
   1. Everyone gets a board
   2. Build and install u-boot:
      1. Figure out the config to use for your board, do:
         cd u-boot
         grep -l SUNXI configs/*_defconfig
      2. Build u-boot for your board, do:
         make -j4 CROSS_COMPILE=arm-linux-gnu- $foo_defconfig
         make -j4 CROSS_COMPILE=arm-linux-gnu-
