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

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.
