Linux port for the 440EP processor

Linux port for the 440EP processor

[Mukund JB.]

Hi Eugene,

I am need of 440EP Processor based Linux port.
I have some questions for what I am not sure of the answers I have.

Does 440EP processor come under 4xx type?
Is there a central repository for Linux distributions for 440 series?
Are there any tools, help Documents that can help build Linux
distribution for the 440EP Processor?
In "Linux for PowerPC Embedded Systems HOWTO" Document, the Target
Hardware's 4xx series points to some site addr & I didn't find any 440
processor support there?=20

Do I have access to the working 440GP & 440GX in both 2.4 & 2.6
developed by u? where can I find them?

Thanks for the support in advance.

Regards,
Mukund jampala

Yes. But AFAIK 440EP port isn't available publicly, yet.

440 isn't something special, currently all 2.6 work is done in 
kernel.org tree. For more info, see http://penguinppc.org/kernel/

You can consider MontaVista Linux (www.mvista.com). Currently they 
support 440GP & 440GX. You can also take a look at www.denx.de, 
although I have no idea how good is 44x support they provide.

Trying mailing support@amcc.com. Their engineers did the 440EP Linux
port. They should be able to provide you with source code for
everything.

Been there, done that.  The only code they will hand out is the custom
IBM OS stuff they have. I have talked to the VP of the embedded
processor division, all the way on down. 

But I would be happy if somebody would prove me wrong - I think the semi
makers should provide Linux drivers available on their website.  I know
AMD has a bunch of drivers for their embedded chips on theirs.

Any Linux code, at this point anyways, has to be gotten from somebody
other than AMCC. However, I will be speaking to their director of
software engineering tommorrow, about all these Linux issues. Maybe
things will change. 

Cheers,
Rick

Bummer.

Actually, I'd rather see the code in the mainline tree where it can
be maintained. Stuff on vendor sites tends to mold.

Sounds good.
