To clarify for everyone, the first part of this series fixes some alignment issues for things that were not starting address aligned. There still exist end-address alignment issues within ehci-hcd. The time I have for this problem right now boils down to disable dcache for these boards so that USB is still functional.
To clarify it even further -- it always worked just by sheer coincidence ...
Not exactly. It never worked (at least on my systems) with D-Cache enabled. But at least we had a choice of run-time disabled dcache. With the recent changes we have to disable cache support at compile time.
I see what you're after. But do you consider runtime disabling the cache is the way to go or it's a way of hiding bugs?
Regards, Ilya.
