3aefca1073 Remove the ARM_DEVICE_MULTIPASS option and make its effect be the default.
Multipass device attachment was tested on many arm platforms by users and
only success was reported on the arm@ mailing list.  This is just the
long-delayed followup of making it the default.

Multipass attachment is necessary when using vendor-supplied FDT data,
because our devices may need to be attached in a different order than they
are described in the FDT data.

AT91SAM9G45_IRQ_PIODE.  According to the data sheet, both PIOD and PIOE

f4c59deacc Implement the FDT static pinctl/pinmux spec for Atmel. This will
configure the mux and config registers for PIO devices based on what
we find in the FDT. I developed it per the spec that had been
committed to Linux in the January 2014 time frame and haven't
updated. In short, bundles of pins are activated in specific ways for
specific configurations, and we implement all of that.

What's not included is a MI device infrastructure, any dynamic
run-time changing of these pins, etc. Also not included are hooks into
all the drivers to enable the latter (static at boot no driver changes
are needed). These larger questions will need to be answered once we
have more drivers like this for more platforms, or somebody has a heck
of a lot of time to research a bunch of platforms, the Linux solution
(which is good, but has its warts), etc.

dc346017bf Add AIC to at91sam9260 support, now that it is needed for multipass to

de01564f85 Don't bother clearing maps for static DMA allocations to NULL. Instead,

e8769d6be2 Fix various NIC drivers to properly cleanup static DMA resources.
In particular, don't check the value of the bus_dma map against NULL
to determine if either bus_dmamem_alloc() or bus_dmamap_load() succeeded.
Instead, assume that bus_dmamap_load() succeeeded (and thus that
bus_dmamap_unload() should be called) if the bus address for a resource
is non-zero, and assume that bus_dmamem_alloc() succeeded (and thus
that bus_dmamem_free() should be called) if the virtual address for a
resource is not NULL.

In many cases these bugs could result in leaks when a driver was detached.

56f425f93e When mapping device memory, use PTE_DEVICE rather than PTE_NOCACHE.
On armv4 these are defined as synonyms right now, but it's a bit ambiguous
what NOCACHE means (is buffering/write-combining also enabled or not?); this
is a first step towards replacing PTE_NOCACHE with a less ambiguous name.

e825adc7a6 Eliminate irq_dispatch.S. Move the data items it contained into arm/intr.c
and the functionality it provided into arm/exception.S.  Rename the main
irq handling routine from arm_handler_execute() to arm_irq_handler() to
make it more congruent with how other exception handlers are named, and
also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.

3b592f9410 The arm exception entry points currently vector through a function pointer
to the actual handler routine.  All the pointers are static-intialized to
the only handlers available, and yet various platform-specific inits still
set those pointers (to the values they're already initialized to).  Begin
to drain the swamp by removing all the redundant external declarations and
runtime setting of the pointers that's scattered around various places.

4ca4e5e369 Rework the EARLY_PRINTF mechanism. Instead of defining a special eprintf()
routine, now a platform can provide a pointer to an early_putc() routine
which is used instead of cn_putc().  Control can be handed off from early
printf support to standard console support by NULLing out the pointer
during standard console init.

This leverages all the existing error reporting that uses printf calls,
such as panic() which can now be usefully employed even in early
platform init code (useful at least to those who maintain that code and
build kernels with EARLY_PRINTF defined).

Real means the one TSC / Symmetricom / Microsemi actually uses on their 4370

board init code can do, including adjusting the master clock frequency.
