Harald Seiler 35b65dd8ef reset: Remove addr parameter from reset_cpu() 
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)
    { ... }

Introduction
============

HiKey960 is one of the 96Boards Consumer Edition board from HiSilicon.
The board/SoC has: -
* HiSilicon Kirin960 (HI3660) SoC with 4xCortex-A73 and 4xCortex-A53
* ARM Mali G71 MP8 GPU
* 3GB LPDDR4 SDRAM
* 32GB UFS Flash Storage
* microSD
* 802.11a/b/g/n WiFi, Bluetooth

More information about this board can be found in 96Boards website:
https://www.96boards.org/product/hikey960/

Currently the u-boot port supports: -
* SD card

Compile from source
===================

First get all the sources

  > mkdir -p ~/hikey960/src ~/hikey960/bin
  > cd ~/hikey960/src
  > git clone https://github.com/ARM-software/arm-trusted-firmware
  > git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
  > git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/config
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/hisi-sec_usb_xloader.img
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/hisi-sec_uce_boot.img
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/sec_xloader.img
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/recovery.bin
  > wget http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey960/release/hikey_idt

Get the SCP_BL2 lpm3.img binary. It is shipped as part of the UEFI source.
The latest version can be obtained from the OpenPlatformPkg repo.

  > cp OpenPlatformPkg/Platforms/Hisilicon/HiKey960/Binary/lpm3.img ~/hikey960/bin/

Compile U-Boot
==============

  > cd ~/hikey960/src/u-boot
  > make CROSS_COMPILE=aarch64-linux-gnu- hikey960_defconfig
  > make CROSS_COMPILE=aarch64-linux-gnu-
  > cp u-boot.bin ~/hikey960/bin/

Compile ARM Trusted Firmware (ATF)
==================================

  > cd ~/hikey960/src/arm-trusted-firmware
  > make CROSS_COMPILE=aarch64-linux-gnu- all fip \
    SCP_BL2=~/hikey960/bin/lpm3.img \
    BL33=~/hikey960/bin/u-boot.bin DEBUG=1 PLAT=hikey960

Copy the resulting FIP binary
  > cp build/hikey960/debug/fip.bin ~/hikey960/bin

Compile l-loader
================
  > cd ~/hikey960/src/l-loader
  > ln -sf ~/hikey960/src/arm-trusted-firmware/build/hikey960/debug/bl1.bin
  > ln -sf ~/hikey960/src/arm-trusted-firmware/build/hikey960/debug/bl2.bin
  > ln -sf ~/hikey960/src/arm-trusted-firmware/build/hikey960/debug/fip.bin
  > ln -sf ~/hikey960/bin/u-boot.bin
  > make hikey960 PTABLE_LST=linux-32g NS_BL1U=u-boot.bin

Copy the resulting binaries
  > cp *.img ~/hikey960/bin
  > cp l-loader.bin ~/hikey960/bin

These instructions are adapted from
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/hikey960.rst

Setup Console
=============

Install ser2net. Use telnet as the console since UEFI in recovery mode
output window fails to display in minicom.

  > sudo apt-get install ser2net

Configure ser2net

  > sudo vi /etc/ser2net.conf

Append one line for serial-over-USB in #ser2net.conf

  > 2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner

Start ser2net

  > sudo killall ser2net
  > sudo ser2net -u

Open the console.

  > telnet localhost 2004

And you could open the console remotely, too.

Flashing
========

1. Boot Hikey960 into recovery mode as per the below document:
https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey960/installation/board-recovery.md

Once Hikey960 is in recovery mode, flash the recovery binary:

  > cd ~/hikey960/src
  > chmod +x ./hikey_idt
  > sudo ./hikey_idt -c config -p /dev/ttyUSB1

Now move to the Hikey960 console and press `f` during UEFI boot. This
will allow the board to boot into fastboot mode. Once the board is in
fastboot mode, you should see the ID of the HiKey960 board using the
following command

  > sudo fastboot devices

1ED3822A018E3372	fastboot

3. Flash the images

Now, the images can be flashed using fastboot:

  > sudo fastboot flash ptable ~/hikey960/bin/prm_ptable.img
  > sudo fastboot flash xloader ~/hikey960/bin/sec_xloader.img
  > sudo fastboot flash fastboot ~/hikey960/bin/l-loader.bin
  > sudo fastboot flash fip ~/hikey960/bin/fip.bin

4. Set the "Boot Mode" switch to OFF position for normal boot mode.
Then power on HiKey960

Observe the console traces using UART6 on the Low Speed Expansion header:
