To be honest both suck in their own way. The only reason why x86 is slightly less horrible is the fact that it's better architectured at the hardware level. But I see the same mess coming in with all those wonderful Atom based SoCs on the horizon, which are nothing else than any other random ARM SoC, just that they glue an x86 core into the same cheepo random IP peripherals conglomerate. In fact some of those chip have been ARM powered before they got an x86 injected. And worse: the Intel folks went there and wrote a new driver for an IP block which had already an "ARM associated" driver. So I say that it is not only an ARM problem, it's a general problem that people do not realize that the IP cores are reused all over the place and across architectures. I'm pretty sure after I went through all the irq code recently that lots of those ARM SoCs from vendors across the board could share a lot of driver code if someone would actually sit down and analyse the situation. Right now we have nobody who has the time and the stomach to go through this and at the same time prevent that more copied crappola is hitting the tree. I'm sure that device tree is part of the solution, but that only helps if we find a way to prevent duplicate drivers in the first place.
