[Buildroot] [PATCH v5 0/3] Fix ATF v2.2 build for rk3399, add roc-rk3399-pc board

[sunil at amarulasolutions.com]

From: Suniel Mahesh <sunil at amarulasolutions.com>

This patch set does the following:
Fix ATF v2.2 build for rk3399 SoC's.
Add arm-gnu-a-toolchain package, which acts as a secondary bare metal toolchain
to build ATF for Rockchip rk3399 platform (has a cortex-m0 core). The required
pre-built toolchain is taken from ARM developers site and installed in host filesystem only.
Add config options for building ATF, targets must enable these configs based on their
requirements in board defconfig.
Add new defconfig file for roc-rk3399-pc.
Update DEVELOPERS file.

The patch set is tested on roc-rk3399-pc, a rk3399 based target. Compile tested on orangepi.
