Ok. I apologize for not checking this. Actually, I only fixed the ones
that I needed to compile.
How should I address the problem? (original code, published on
sourceforge was simply replicating a number of amba drivers into pci
drivers, but I don't think massive code duplication is ever sensible,
thus I preferred to reuse the existing drivers).
I doubt all amba drivers can easily be made x86-compatible.
I see these possible approaces, all of them with their cons
1- add STA2X11 dependencies to ARM_AMBA _and_ the drivers that do work
2- leave CONFIG_ARM_AMBA undefined and play select file in Makefiles
using obj-$(CONFIG_STA2X11)
3- add ARM dependencies to the drivers that do not compile on x86
any other option?
(1) and (2) bring chipset-specific stuff into the amba world, which is
bad, especially since I suspect other similar bridges will appear soon.
(3) looks like a temporary hack and stuff can be fixed over time, but
it has the disadvantage of adding a big number of needless drivers in
the dsitributions' packages -- like my nacked patch did.
