[U-Boot] GSoC projects for Minnowboard MAX

[Simon Glass]

Hi,

Minnowboard is looking for GSoC projects this year.

http://wiki.minnowboard.org/GSoC2016

There are a few things listed in README.x86 to be done. Any ideas?

Regards,
Simon

Maybe speed up USB port scan ? This really needs to be parallelized
by using some for of cooperative multi-tasking.

For starters just parallelizing the scanning of separate controllers
in drivers/usb/host/usb-uclass.c: usb_init() by splitting
usb_scan_bus() into a  usb_scan_bus_start() and usb_scan_bus_get_status()
with the latter being called repeatedly until all busses are done
would already help. Then do something similar for scanning all
ports of a hub in "parallel", etc.

Hans

Yes that sounds good. There is a lot that could be done there. Are you
interested in mentoring a student?

Ideas I have are to port U-Boot to 64-bit, also enable the EFI image
support for x86 (for running grub). Or perhaps just support the grub
format.

Bin, do you have any thoughts?

Simon

What about enable distro configuration for x86? If there are
limitations due to ACPI on Minnowmax, maybe we can switch to QEMU
instead?

What do you mean by distro configuration?

Something else I wonder about is supporting grub's config file
directly in U-Boot.

I was referring to doc/README.distro.

And maybe installing distro from U-Boot?

Just to inform you, so that we don't work on this with multiple people
at the same time and waist resources. I'm currently working on this USB
scan speedup. I suspect to have something ready to publish latest by
end of this week.

Thanks,

Thanks for letting us know, sounds good!
