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 ============ 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: NOTICE: BL2: v2.1(debug):v2.1-531-g3ee48f40 NOTICE: BL2: Built : 18:15:58, Aug 2 2019 INFO: BL2: Doing platform setup INFO: UFS LUN0 contains 1024 blocks with 4096-byte size INFO: UFS LUN1 contains 1024 blocks with 4096-byte size INFO: UFS LUN2 contains 2048 blocks with 4096-byte size INFO: UFS LUN3 contains 7805952 blocks with 4096-byte size INFO: ufs: change power mode success INFO: BL2: Loading image id 2 INFO: Loading image id=2 at address 0x89c80000 INFO: Image id=2 loaded: 0x89c80000 - 0x89cb5088 INFO: BL2: Initiating SCP_BL2 transfer to SCP INFO: BL2: SCP_BL2: 0x89c80000@0x35088 INFO: BL2: SCP_BL2 HEAD: INFO: BL2: SCP_BL2 0x7000 0x179 0x159 0x149 INFO: BL2: SCP_BL2 0x189 0x18b 0x18d 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x18f INFO: BL2: SCP_BL2 0x191 0x0 0x193 0x195 INFO: BL2: SCP_BL2 0x18fd 0x18fd 0x18fd 0x18fd INFO: BL2: SCP_BL2 0x18fd 0x18fd 0x18fd 0x18fd INFO: BL2: SCP_BL2 0x18fd 0x18fd 0x18fd 0x18fd INFO: BL2: SCP_BL2 0x4d454355 0x43494741 0x424d554e 0x21215245 INFO: BL2: SCP_BL2 0x4a054904 0x42912000 0xf841bfbc 0xe7fa0b04 INFO: BL2: SCP_BL2 0xb88cf000 0x3b18 0x3d1c 0x6809493e INFO: BL2: SCP_BL2 0x4613680a 0x201f102 0xf0002a04 0x600a804c INFO: BL2: SCP_BL2 0x204f04f 0xf203fb02 0xf102440a 0x60100204 INFO: BL2: SCP_BL2 0x160f04f 0xf103fb01 0x68004834 0x61044408 INFO: BL2: SCP_BL2 0x61866145 0xf8c061c7 0xf8c08020 0xf8c09024 INFO: BL2: SCP_BL2 0xf8c0a028 0xf3efb02c 0xf3ef8208 0x68118309 INFO: BL2: SCP_BL2 0xf1026401 0xf0110204 0xbf070f04 0x46113220 INFO: BL2: SCP_BL2 TAIL: INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x19cad151 0x19b80040 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 0x0 0x0 0x0 0x0 INFO: BL2: SCP_BL2 transferred to SCP INFO: start fw loading INFO: fw load success WARNING: BL2: Platform setup already done!!
