Hi,
  This series fixes fastboot to allow its use on non-android systems.  I've tried it on android and ubuntu, and can flash bits of the bootloader, and boot uImage, zImage and raw images.  (For raw images, you need to specify the base address to fastboot; the blob entry point will be 0x8000 above the specified base address.  Like  this:
   fastboot boot -b 0x43DF8000 u-boot.bin
to boot a new u-boot at 0x43e00000)

I have the series (not from me) to boot in HYP mode waiting too.  I'll make that a separate pull request.
