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)

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!
