[Buildroot] [PATCH v2 2/2] configs/orangepi_rk3399: new defconfig

[sunil at amarulasolutions.com <sunil@amarulasolutions.com>]

From: Suniel Mahesh <sunil@amarulasolutions.com>

Add initial support for Orangepi RK3399 target with below features:

  - U-Boot 2020.04
  - Linux 5.4.35
  - Default packages from buildroot

Signed-off-by: Suniel Mahesh <sunil@amarulasolutions.com>
---
Changes for v2:
- change contact for just only orangepi-rk3399.
- As suggested by Thomas Pettazzoni, rk3399 targets does not need
  pylibfdt or pyelftools, but only a host Python interpreter. Remove
  them and add python, python3 in defconfig.

+================
+http://www.orangepi.org/Orange%20Pi%20RK3399/
+
+Build:
+======
+  $ make orangepi_rk3399_defconfig
+  $ make
+
+Files created in output directory

+????????? bl31.elf

+
+Creating bootable SD card:
+==========================
+
+Simply invoke (as root)
+
+sudo dd if=output/images/sdcard.img of=/dev/sdX && sync
+
+Where X is your SD card device.
+
+Booting:
+========
+Orangepi-RK3399 by default boots from emmc. For SD card boot to
+happen, emmc should be empty. If emmc happens to have any bootable
+image then erase emmc so that bootrom will look for a proper image in SD.
+
+emmc can be erased once after booted into linux as shown in below link.

+Serial console:
+---------------
+
+Baudrate for this board is 1500000.
+
+Login:
+------
+Enter 'root' as login user, and the prompt is ready.
