This adds platform code for the Amlogic P212 reference board based on a
Meson GXL (S905X) SoC with the Meson GXL configuration.

This initial submission only supports UART and MMC/SDCard, support for the
internal Ethernet PHY in Work In Progress.

+U-Boot for Amlogic P212
+=======================
+
+P212 is a reference board manufactured by Amlogic with the following
+specifications:
+
+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
+ - ARM Mali 450 GPU
+ - 2GB DDR3 SDRAM
+ - 10/100 Ethernet
+ - HDMI 2.0 4K/60Hz display
+ - 2 x USB 2.0 Host
+ - eMMC, microSD
+ - Infrared receiver
+ - SDIO WiFi Module
+ - CVBS+Stereo Audio Jack
+
+Schematics are available from Amlogic on demand.
+
+Currently the u-boot port supports the following devices:
+ - serial
+ - eMMC, microSD
+
+u-boot compilation
+==================

+
+Image creation
+==============
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:
