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.

SOC  Hisilicon Hi3798CV200
CPU  Quad-core ARM Cortex-A53 64 bit
DRAM DDR3/3L/4 SDRAM interface, maximum 32-bit data width 2 GB
USB  Two USB 2.0 ports One USB 3.0 ports

DIMENSION Standard 160×120 mm 96Boards Enterprice Edition form factor
WIFI  802.11AC 2*2 with Bluetooth
CONNECTORS  One connector for Smart Card One connector for TSI

The platform boot sequence is as follows:
    l-loader --> arm_trusted_firmware --> u-boot

Repositories:

 - https://github.com/Linaro/poplar-u-boot.git



U-Boot is also upstream in the project's master branch.

Make sure you are using the correct branch on each one of these
repositories. The definition of "correct" might change over time (at
this moment in time this would be the "latest" branch).

+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.
