 * LeMaker Banana Pi

Current issues / problems encountered:
 * U-Boot regression: This commit breaks the ability to FEL-boot the Banana Pi. When installed to SD card, the resulting u-boot-sunxi-with-spl.bin still seems to work.
 * U-Boot regression: The same commit (switch to driver model) breaks U-Boot compilation when  is defined (reported to ML). (CONFIG_DM_ETH also causes other issues.)
 * U-Boot regression: Looks like the Banana Pi ethernet (GMAC) no longer works with v2015.07-rc1 ("failed to reset DMA"). Still needs further investigation / git bisect. (Possibly related?)

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.

If  is enabled, mainline U-Boot compilation currently (June 2015) might fail on armhf ("hardfloat") toolchains. This patch fixes that.
