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
============

HiKey is the first certified 96Boards Consumer Edition board. The board/SoC has: -
* HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz.
* ARM Mali 450-MP4 GPU
* 1GB 800MHz LPDDR3 DRAM
* 4GB eMMC Flash Storage
* microSD
* 802.11a/b/g/n WiFi, Bluetooth

The HiKey schematic can be found here: -
https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/HiKey_schematics_LeMaker_version_Rev_A1.pdf

The SoC datasheet can be found here: -
https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf

Currently the u-boot port supports: -
* USB
* eMMC
* SD card
* GPIO

The HiKey U-Boot port has been tested with l-loader, booting ATF, which then boots
U-Boot as the bl33.bin executable.

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

First get all the sources

  > mkdir -p ~/hikey/src ~/hikey/bin
  > cd ~/hikey/src
  > git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
  > git clone https://github.com/ARM-software/arm-trusted-firmware
  > git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
  > git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
  > git clone https://github.com/96boards-hikey/atf-fastboot
  > wget https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/hisi-idt.py

Get the BL30 mcuimage.bin binary. It is shipped as part of the UEFI source.
The latest version can be obtained from the OpenPlatformPkg repo.

  > cp OpenPlatformPkg/Platforms/Hisilicon/HiKey/Binary/mcuimage.bin ~/hikey/bin/

Get nvme.img binary
  > wget -P ~/hikey/bin https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/nvme.img

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

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

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

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

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

Compile ATF Fastboot
====================

  > cd ~/hikey/src/atf-fastboot
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=hikey DEBUG=1

Compile l-loader
================
  > cd ~/hikey/src/l-loader
  > ln -sf ~/hikey/src/arm-trusted-firmware/build/hikey/debug/bl1.bin
  > ln -sf ~/hikey/src/arm-trusted-firmware/build/hikey/debug/bl2.bin
  > ln -sf ~/hikey/src/atf-fastboot/build/hikey/debug/bl1.bin fastboot.bin
  > make hikey PTABLE_LST=aosp-8g

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

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

FLASHING
========

1. Connect the second jumper on J15 BOOT SEL, to go into recovery mode and flash l-loader.bin with
the hisi-idt.py utility. Then connect a USB A to B mini cable from your PC to the USB OTG port of HiKey and execute the below command.

The command below assumes HiKey enumerated as the first USB serial port

  > sudo python ~/hikey/src/hisi-idt.py -d /dev/ttyUSB0 --img1 ~/hikey/bin/recovery.bin

2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device.

  > sudo fastboot devices

0123456789ABCDEF	fastboot

3. Flash the images

  > sudo fastboot flash ptable ~/hikey/bin/prm_ptable.img
  > sudo fastboot flash loader ~/hikey/bin/l-loader.bin
  > sudo fastboot flash fastboot ~/hikey/bin/fip.bin
  > sudo fastboot flash nvme ~/hikey/bin/nvme.img

4. Disconnect second jumper on J15 BOOT SEL, and reset the board and you will now (hopefully)
   have ATF, booting u-boot from eMMC.

   Note: To get USB host working, also disconnect the USB OTG cable used for flashing. Otherwise you
   will get 'dwc_otg_core_host_init: Timeout!' errors.
