Re: new powerpc hardware


It sounds like there isn't much hope to get NetBSD ported to the sam440ep unless the 440 is very simlar to the PPC chips that NetBSD already supports. I have tried emailing the makers of the sam440ep with no response as to whether they would consider porting NetBSD to it. Their web site does say they have plans to port FreeBSD to it.

Would something like this be easier:

Although, it's size would make it less than preferable to colocate.

Best Regards,

I was under the impression that the 440 was some kind of a PowerPC clone.

There are several different families of PowerPC chips.

The ones I can think of off-hand (I haven't done much with PPC lately):

* Motorola/IBM 60x / G2/G3/G4 series.
* IBM 970 (Apple's "G5")
* Motorola 82xx (really G2/G3 + peripherals)
* Motorola 860 and variants
* Motorola 85xx
* IBM/AMCC 4xx (401, 405, 440, etc.)

Within each family, there are some similiarities, but sometimes some
significant differences, as between the 405 and 440.

The IBM/AMCC 4xx, especially, have a number of differences even between
different chips with the same number.  The 405 and 440 each have a
number of variants with the same CPU core and different integrated
busses and peripherals.  I think Motorola does the same thing with
the 860/82xx/85xx.
