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> |

Here is the step-by-step to boot U-Boot on phytium durian board. Compile U-Boot ============== > make durian_defconfig > make Get the prebuild binary about BPF ================================= > cd ../ > git clone https://github.com/phytium-durian/bpf.git Package the image ================= > cd bpf > cp ../u-boot/u-boot.bin ./ > ./dopack The fip-all.bin is the final image. Flash the image into the spi nor-flash ====================================== Any spi nor-flash and appropriate tool can be used to flash. For example, we choose the S25FL256 chip that produced from SPANSION company and EZP_XPro V1.2. Reset the board, you can get U-Boot log message from boot console: Power on... Start pcie setup! End pcie setup! Start ddr setup! End ddr setup!
