Tom Rini db7516b635 board: Remove essentially empty board files and Makefiles 
As part of reviewing a new platform, Daniel Schwierzeck noted that we
can have an empty Makefile in the board directory and don't need an
empty board.c file as well.  Further with further cleanup in the
Makefile we can now omit the Makefile entirely. Remove a number of now
unnecessary board.c and Makefiles.

Here is the step-by-step to boot to U-Boot on RK3368-uQ7

Get the Source and build ATF
============================

  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
  > cd arm-trusted-firmware
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31
  > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin

Configure U-Boot
================

  > cd ../u-boot
  > make lion-rk3368_defconfig

Build the TPL/SPL stage
=======================

  > make CROSS_COMPILE=aarch64-unknown-elf-

Build the full U-Boot and a FIT image including the ATF
=======================================================

  > make CROSS_COMPILE=aarch64-unknown-elf- u-boot.itb

Flash the image
===============

Copy the SPL to offset 32k and the FIT image containing the payloads
(U-Boot proper, ATF, devicetree) to offset 256k card.

SD-Card
-------

  > dd if=idbloader.img of=/dev/sdb seek=64
  > dd if=u-boot.itb of=/dev/sdb seek=512

eMMC
----

rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
help of the Rockchip loader binary.

  > git clone https://github.com/rockchip-linux/rkdeveloptool
  > cd rkdeveloptool
  > autoreconf -i && && ./configure && make
  > git clone https://github.com/rockchip-linux/rkbin.git
  > ./rkdeveloptool db rkbin/rk33/rk3368_loader_v2.00.256.bin
  > ./rkdeveloptool wl 64 ../spl.img
  > ./rkdeveloptool wl 512 ../u-boot.itb


If everything went according to plan, you should see the following
output on UART0:
