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) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> |

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.
