Benjamin,
Out of order execution != out of order storage. ioremap() will give you
guarded space which means it cannot be speculatively accessed for
example, and you do get -some- guarantees but not that your stores are
going to hit the device in order, nor that your loads are going to be

Hi,

Looks like your patch converts the driver from mpc5200 to mpc5200b? If this is
really all which is needed, it should support both versio

Benjamin,
Also, if you're going to access a PCI device directly, beware of other
issues such as ordering. PPC is an out of order architecture, you need
to ensure you add the appropriate memory barriers if you want to ensure
you accesses are done in the order you write them in your program.

Hi,
Iam getting the below crash on new board tested on MPC832x using
linux-2.6.24, please let me what could be the problem on the same. Does it
infer any information on the exception?

We have built some custom hardware based on a PPC440EPx. I saw
an oops that doesn't make much sense to me, so I'd like to ask
folks if this smells more like a hardware problem than a software
problem.
The oops is a signal 4 in kernel mode (trap 700). If I'm
interpreting this correctly, it is a "

Ok, I wrongly understood protected interrupts as reserved for

Otherwise it may work if every interrupt is delivered to both
