Known Issues
------------
* Poor libmali (fbdev) performance: It seems the libmali.so (fbdev) rockchip
  compiled for us is not using dma_bufs. Executing es2gears with a higher
  resolution (1920x1080) will show low FPS rates. A live analysis with
  'perf top'  shows the bottleneck, which is memcpy. So it seems, that (only)
  the CPU is copying data from the GPU buffer into the display controller's
  frame buffer.
* USBHOST1 which is usb_host0_ehci is not working (It is limited by SoC design)
* eMMC cold resets can bring the eMMC card in a bad state.
  See https://marc.info/?t=147263755200005&r=1&w=3
* USB EHCI is working but the driver is not aktivated
* qtwebkit is not installed

 
Fixed Issues
------------
 
* SPI nor flash is now working (Disabled DMA)
* Access to the full RAM (Wrong RAM configuration in u-boot-spl)
