I have no attachment to 40x, and I'd certainly be happy to have less code in the tree, we struggle to keep even the modern platforms well maintained.
At the same time I don't want to render anyone's hardware obsolete unnecessarily. But if there's really no one using 40x then we should remove it, it could well be broken already.
So I guess post a series to do the removal and we'll see if anyone speaks up.
We shouldn't remove 40x completely. Just remove the Xilinx 405 stuff.
Congratulations on becoming the 40x maintainer!
Didn't I give you my last 40x system ? :-) IBM still put 40x cores inside POWER chips no ?
According to Wikipedia (https://en.wikipedia.org/wiki/PowerPC_400), 405 cores are used in modern equipments (how modern ?), however 403 has never reached the market.
Can we start removing 403 stuff ? That's not a lot, but still.
Does anybody knows anything about this ERRATUM 77 stuff ? Is that still an issue with all 405 cores or has this been fixed long time ago and can be removed ?
