microblaze: Add architectural support for USB EHCI host controllers Add architectural support for USB EHCI host controllers. It has been tested using the USB EHCI host controller from Xilinx Inc., using both High Speed devices and Full Speed devices.

microblaze: Stack trace support This is working implemetation but the problem is that Microblaze misses frame pointer that's why is there big loop which trace and show all addresses which are in text. It shows addresses which are in registers, etc. This is problem and this is the reason why all Microblaze traces are wrong. There is an option to do hacks and trace the kernel code but this is too complicated. Signed-off-by: Michal Simek <monstr@monstr.eu>

microblaze: Lockdep support Microblaze needs to do lock_init very soon because MMU init calls lock functions. Here is the explanation from Peter Zijlstra why we have to enable __ARCH_WANTS_INTERRUPTS_ON_CTSW. "So we schedule while holding rq->lock (for obvious reasons), but since lockdep tracks held locks per tasks, we need to transfer the held state from the prev to the next task. We do this by explicity calling spin_release(&rq->lock) in context_switch() right before switch_to(), and calling spin_acquire(&rq->lock) in finish_task_switch()->finish_lock_switch(). Now, for some reason lockdep thinks that interrupts got enabled over the context switch (git grep __ARCH_WANTS_INTERRUPTS_ON_CTSW arch/microblaze doesn't seem to turn up anything). Clearly trying to acquire the rq->lock with interrupts enabled is a bad idea and lockdep warns you about this." Signed-off-by: Michal Simek <monstr@monstr.eu>

microblaze: use generic dma-mapping-broken.h Microblaze does not support the Linux DMA mapping API at this point, so disable CONFIG_NO_DMA. This lets us use the generic dma-mapping-broken.h implementation instead of providing a different copy. Any drivers that try to use DMA mapping now get omitted from Kconfig or produce a link error, rather than failing silently at run time.
