Poplar: Initial commit for Poplar E-96Boards

The board features the Hi3798C V200 with an integrated quad-core
64-bit ARM Cortex A53 processor and high performance Mali T720 GPU,
making it capable of running any commercial set-top solution based on
Linux or Android. Its high performance specification also supports a
premium user experience with up to H.265 HEVC decoding of 4K video at
60 frames per second.

+Description
+===========
+
+Poplar is the first development board compliant with the 96Boards Enterprise
+Edition TV Platform specification.
+
+The board features the Hi3798C V200 with an integrated quad-core 64-bit
+ARM Cortex A53 processor and high performance Mali T720 GPU, making it capable
+of running any commercial set-top solution based on Linux or Android.
+
+It supports a premium user experience with up to H.265 HEVC decoding of 4K
+video at 60 frames per second.

+
+At the start of the boot sequence, the bootROM executes the so called l-loader
+binary whose main role is to change the processor state to 64bit mode. This
+must  happen prior invoking the arm trusted  firmware:
+
+    l-loader --> arm_trusted_firmware --> u-boot
+
+How to build
+============
+
+Code Locations
+--------------
+
+-  ARM Trusted Firmware:
+   `link <https://github.com/ARM-software/arm-trusted-firmware>`__
+
+-  l-loader:
+   `link <https://github.com/Linaro/poplar-l-loader.git>`__
+
+-  u-boot:
+   `link <http://git.denx.de/u-boot.git>`__
+
+Build Procedure
+---------------
+
+-  Fetch all the above 3 repositories into local host.
+   Make all the repositories in the same ${BUILD\_PATH}.
+
+-  Prepare the AARCH64 toolchain.
+
+-  Build u-boot using poplar_defconfig
+       make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig
+       make CROSS_COMPILE=aarch64-linux-gnu-
+
+-  Build atf providing the previously generated u-boot.bin as the BL33 image
+       make CROSS_COMPILE=aarch64-linux-gnu-  all fip SPD=none PLAT=poplar
+       BL33=u-boot.bin
+
+-  Build l-loader (generated the final fastboot.bin)
+       1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/
+       2. export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH)
+       3. make
+
+Install Procedure
+-----------------
+
+- Copy l-loader/fastboot.bin to a FAT partition on a USB pen drive.
+
+- Plug the USB pen drive to any of the USB2 ports
+
+- Power the board while keeping S3 pressed (usb_boot)
+
+The system will boot into a u-boot shell which you can then use to write the
+working firmware to eMMC.

+
+/*
+ * When Poplar is powered on, boot ROM loads the initial content of
+ * boot media into low memory, verifies it, and begins executing it
+ * in 32-bit mode.  The image loaded is "l-loader.bin", which contains
+ * a small amount code along with an embedded ARM Trusted Firmware
+ * BL1 image.  The main purpose of "l-loader" is to prepare the
+ * processor to execute the BL1 image in 64-bit mode, and to trigger
+ * that execution.
+ *
+ * Also embedded in "l-loader.bin" is a FIP image that contains
+ * other ARM Trusted Firmware images:  BL2; BL31; and for BL33,
+ * U-Boot.  When BL1 executes, it unpacks the BL2 image from the FIP
+ * image into a region of memory set aside to hold it.  Similarly,
+ * BL2 unpacks BL31 into memory reserved for it, and unpacks U-Boot
+ * into high memory.
+ *
+ * Because the BL1 code is embedded in "l-loader", its base address
+ * in memory is derived from the base address of the "l-loader"
+ * text section, together with an offset.  Memory space for BL2 is
+ * reserved immediately following BL1, and memory space is reserved
+ * for BL31 after that.  ARM Trusted Firmware requires each of these
+ * memory regions to be aligned on page boundaries, so the size of
+ * each region is a multiple of a page size (ending in 000).  Note
+ * that ARM Trusted Firmware requires the read-only and read-write
+ * regions of memory used for BL1 to be defined separately.
