Jorge Ramirez-Ortiz d754254f20 ARM64: poplar: hi3798cv200: u-boot support for Poplar 96Boards 
This port adds support for:
        1) Serial
        2) eMMC
        3) USB

It has been tested with ARM TRUSTED FIRMWARE running u-boot as the
BL33 executable [see board's README]

eMMC has been tested for reading and booting the loader and linux
kernels as well as saving the u-boot environment.

USB has been tested with ASIX networking adapter and SanDisk 7.4GB
drive.

PSCI has been tested via the reset call (PSCI executes from DDR)

The firwmare upgrade process has been tested via TFTP and USB FAT
filesystem containing the fastboot.bin image in one of the partitions.

Note of warning:
================
U-boot has a *strong* dependency with the l-loader and the arm trusted firmware
repositories.
The boot sequence is:
l-loader --> arm_trusted_firmware --> u-boot
U-Boot needs to be aware of the BL31 runtime location and size to avoid writing
over it. Currently, BL31 is being placed below the kernel text offset (check
poplar.c) but this could change in the future.
The current version of u-boot has been tested with:

l-loader: use external memory region definitions
The ARM Trusted Firmware code now has a header file that collects
all the definitions for the memory regions used for its boot stages.
Include that file where needed, and use the definitions found therein

poplar: define memory regions in a separate file
Separate the definitions for memory regions used for the BL stage
images and FIP into a new file. The "l-loader" image uses knowledge
of the sizes and locations of these memory regions, and it can now
include this (external) header to get these definitions, rather than
having to make coordinated changes to both code bases.
The new file has a complete set of definitions (more than may be
required by one or the other user). It also includes a summary of
how the boot process works, and how it uses these regions.
It should now be relatively easy to adjust the sizes and locations
of these memory regions, or to add to them (e.g. for TEE).

Compile from source:
====================
Get all the sources
> mkdir -p ~/poplar/src ~/poplar/bin
> cd ~/poplar/src
> git clone https://github.com/Linaro/poplar-l-loader.git l-loader
> git clone https://github.com/Linaro/poplar-arm-trusted-firmware.git atf
> git clone https://github.com/Linaro/poplar-u-boot.git u-boot
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).
Compile U-Boot:
===============
Prerequisite:
# sudo apt-get install device-tree-compiler
> cd ~/poplar/src/u-boot
> make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig
> make CROSS_COMPILE=aarch64-linux-gnu-
> cp u-boot.bin ~/poplar/bin
Compile ARM Trusted Firmware (ATF):
===================================
> cd ~/poplar/src/atf
> make CROSS_COMPILE=aarch64-linux-gnu- all fip \
SPD=none BL33=~/poplar/bin/u-boot.bin DEBUG=1 PLAT=poplar
Copy resulting binaries
> cp build/hi3798cv200/debug/bl1.bin ~/poplar/src/l-loader/atf/
> cp build/hi3798cv200/debug/fip.bin ~/poplar/src/l-loader/atf/
Compile l-loader:
=================
> cd ~/poplar/src/l-loader
> make clean
> make CROSS_COMPILE=arm-linux-gnueabi-
Due to BootROM requiremets, rename l-loader.bin to fastboot.bin:
> cp l-loader.bin ~/poplar/bin/fastboot.bin
================================================================================
FLASH INSTRUCTIONS
================================================================================
Two methods:
Using USB debrick support:
Copy fastboot.bin to a FAT partition on the USB drive and reboot the
poplar board while pressing S3(usb_boot).
The system will execute the new u-boot and boot into a shell which you
can then use to write to eMMC.
Using U-BOOT from shell:
1) using AXIS usb ethernet dongle and tftp
2) using FAT formated USB drive
1. TFTP (USB ethernet dongle)
=============================
Plug a USB AXIS ethernet dongle on any of the USB2 ports on the Poplar board.
Copy fastboot.bin to your tftp server.
In u-boot make sure your network is properly setup.
Then
=> tftp 0x30000000 fastboot.bin
