Whenever I added a new host tool in scripts/ I usually ended up copying
functions from other host tools and thought it's about time to create
a library for sharing code between the host tools. Not this time. I
finally added such a library. I have no idea how a library can be built
(and used by host programs) with Kbuild, so I took the easy way out
and included a C file where needed instead of building a library.
I'm open for suggestions how this can be improved.
Last patch of this series adds a rk-usb-loader tool suitable for
bootstrapping barebox on a Rockchip RK3568 via USB.

Host tools were often only compiled depending on the architecture which
needs them. This patch adds explicit options for most tools mainly to
be able to compile test them without having to compile for each
architecture.

Several functions are duplicated in different host tools. This patch
starts collecting them in a single C file. We start with read_file()
and read_file_2(), others follow in separate commits.
It would be great to compile these functions in a separate library, but
I don't know how this can be archieved in Kbuild. Instead, the C file
is included where needed. Not nice, not beautiful, but at least enough
to get something going.

write_file() is used once, but can be used in socfpga_mkimage.c as
well. Move function to a common place and use it in the SoCFPGA image
tool.

We have different implementations of read_full() and write_full() in our
host tools, use a common implementation for these.

This adds a tool suitable for bootstrapping barebox on Rockchip RK3568
SoCs. It has been tested on this SoC only. It might or might not work
with minor adjustments on other SoCs.

very nice! I was able to load barebox images into the RAM of the RK3568
EVB1 as well as of the Pine64 Quartz64A boards. So it works for the
RK3566 as well, maybe this should be reflected in the comments and the
commit message.
Also, if it is not too much to ask, a short hint to this tool in the
documentation would be nice.

I added a text to the documentation and also a note about the RK3566 to
the top of the tool's sourcecode.

I hardcoded the vid/pid of the RK3568 here. Is it the same for the
RK3566 or did you have to change it?

The RK3566 has the same VID/PID:
ID 2207:350a Fuzhou Rockchip Electronics Company
and I guess the IDs can remain hardcoded for now.

You can try this.
hostprogs-always-$(CONFIG_IMD) += bareboximd
bareboximd-objs := bareboximd.o common.o
hostprogs-always-$(CONFIG_OMAP3_USB_LOADER) += omap3-usb-loader
omap3-usb-loader-objs := omap3-usb-loader.o common.o

I did and it works well as long as common.o is used only in a single
directory. Unfortunately some tools are in subdirectories, like for
example scripts/imx/imx-usb-loader.c. Of course these could be moved up
one level, but I didn't want to go that path.
Do you see any possibility to archieve the same with files in different
directories?

Then, I have no idea.
At least, the Makefile part needs to be moved up.
hostprogs-always-$(CONFIG_ARCH_IMX_IMXIMAGE) += imx-image
imx-usb-loader-objs := imx/imx-usb-loader.o imx/imx.o common.o
Probably, you do not want to do it.
