Boot program interface

Boot program interface

[Carlos Mitidieri]

Hello,

I am working on a project that requires an extensive boot program interface.

It turns out that the device tree used on PPC architecture meets the
requirements.

I have been looking, and I could not find any similar concept implemented for
MIPS.

So, I am now considering to port the OFDT library into the MIPS arch.

What do you think about this? Is there anyone working on a similar project?

Best regards,

I do not know any MIPS board using a device tree either.

You should see how Sparc, PowerPC and Microblaze use it and how they do share 
code. Also condiser seeing how u-boot handles device trees, specifically on 
PowerPC and Microblaze.

Hope that helps.

Ok, but what you think about doing such a port? I mean, is it something that
could be eventually accepted by the MIPS Linux community? Or do you have
problems with this approach?

I am looking forward for your answers.

Kind regards,

We have a working version of the device tree for MIPS. I'll see if we can expedite a patch.
