Right, I think I've heard about it...
To be honest, I have rather mixed feelings about it. In particular I
could say that if qemu returns r0p0, it doesn't model V2P-CA9, which has
A9 r0p1 :-) Also, the DEBUG_LL and EARLY_PRINTK are pretty low level
features and it seems that they simply shouldn't be enabled in the
defconfig. As I'll be updating defconfig soon, I'll make sure they're
disabled.
Yes, I agree that the "detection" code is a hack. I'm not sure we have
to make it even hackier. Let me have a think about it, as I can't really
spend any time of the matter this week, sorry.
Thanks for your efforts!
Pawel
