Since there was no feedback on this, I investigated a little further and I noticed that several existing ARM cores already do it this way (arm926ejs, arm926ejs, arm920t, etc) so I think there's then a nice prejudice to continue on this path.
yes that's the correct idea
I've some old patch that start to do it if you are interrested to continue on it
If you post it (or point me to where I can find it) I can at least get a grip of what you're suggesting and then see what I can do.
My actual plan is to help get the colibri-pxa270 stuff merged in, but it seems we should fix some duplication first to make way for that.
But only one of these are PXA270 based, and I'm not fluent enough in the PXA world to tell how much that can be re-used between PXA models or similar.
for the pxa2xx I can help you, for the pxa3xx I've no board
I'll very soon not have any PXA board at all... :-) I was mostly (at this point) thinking about the knowledge about how they differ and similar. I mean, does it make sense to try to make a single lowlevel_init.S for all PXAXXX models or one for each PXA2xx/PXA3xx or do we need PXA25x/PXA27X/PXA3xx etc...
But I guess your initial patch might reveal that to me?
