Subject: [PATCH 39/93] armv8: ls1012a: Add support of ls1012afrdm board

QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance
development platform, with a complete debugging environment.
The LS1012AFRDM board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

+Overview
+--------
+The LS1012AFRDM power supplies (PS) provide all the voltages necessary
+for the correct operation of the LS1012A processor, DDR3L, QSPI memory,
+and other onboard peripherals.

+ - One Configurable x3 SerDes:
+    Two Serdes PLLs supported for usage by any SerDes data lane
+    Support for up to 6 GBaud operation
+ - High-speed peripheral interfaces:
+     - One PCI Express Gen2 controller, supporting x1 operation
+     - One serial ATA (SATA Gen 3.0) controller
+     - One USB 3.0/2.0 controller with integrated PHY

+ - Additional peripheral interfaces:
+    - One quad serial peripheral interface (QuadSPI) controller
+    - One serial peripheral interface (SPI) controller
+    - Two enhanced secure digital host controllers
+    - Two I2C controllers
+    - One 16550 compliant DUART (two UART interfaces)
+    - Two general purpose IOs (GPIO)
+    - Two FlexTimers
+    - Five synchronous audio interfaces (SAI)
+    - Pre-boot loader (PBL) provides pre-boot initialization and RCW loading
+    - Single-source clocking solution enabling generation of core, platform,
+    DDR, SerDes, and USB clocks from a single external crystal and internal
+    crystaloscillator
+    - Thermal monitor unit (TMU) with +/- 3C accuracy
+    - Two WatchDog timers
+    - ARM generic timer
+ - QorIQ platform's trust architecture 2.1
