A20

 * LeMaker Banana Pi

Current issues / problems encountered:
 * U-Boot regression: For v2015.07 the switch to driver model breaks U-Boot compilation when  is defined (reported to ML). v2015.10 fixed that.

I'm currently staying with (and recommending) U-Boot release v2015.04 for the BPi. That version works well while enabling all the features I tend to use. As of v2015.10, U-Boot support is rather complete again - one missing thing is support for the (green) status led.

Cortex-M3

 * STM32 VL Discovery board

 * Extend "fel spl" command to handle both parts of u-boot-sunxi-with-spl.bin, and have "fel uboot" interact with U-Boot (support autostart of script via bootcmd_fel). Merged into sunxi-tools (and U-Boot v2015.10).
