From Tony Lindgren:
Omap5 SoC data via Paul Walmsley <paul@pwsan.com:

Add support for the OMAP5 SoC family.

As part of the transition to DT, no board files will be used
for OMAP5.  The hwmod data is gradually being transitioned
away from arch/arm/mach-omap2: IRQ, DMA, and memory map data
has been moved to DT.  Hopefully the dev_attr and clock role
data will be the next step.

Basic test logs are available here, although not for OMAP5,
since I don't have an OMAP5 board:

Now that we have two different addresses for the UART, depending on
which bootloader is used, it is no longer desirable to enable
earlyprintk by default in the defconfig. Users who need earlyprintk
support will have to enable it explicitly, and select the right UART
configuration depending on their platform.

In order to support both old and new bootloaders, we add a new Kconfig
option for the earlyprintk UART selection. The existing option allows
to work with old bootloaders (that keep the internal registers mapped
at 0xd0000000), while the newly introduced option allows to work with
new bootloaders (that remap the internal registers at 0xf1000000).

Since the mvebu-mbus driver doesn't yet have a DT binding (and this DT
binding may not necessarily be ready for 3.11), the physical address
of the mvebu-mbus registers are currently hardcoded. This doesn't play
well with the fact that the internal registers base address may be
different depending on the bootloader.

In order to have only one central place for the physical address of
the internal registers, we now use of_translate_address() to translate
the mvebu-mbus register offsets into the real physical address, by
using DT-based address translation. This will go away once the
mvebu-mbus driver gains a proper DT binding.

Now that the coherency_init() function is called a bit earlier, we can

Now that we have removed the need of the static I/O mapping for early
initialization reasons, and fixed the registers area length that were
broken, we can get rid of the static I/O mapping. Only the earlyprintk
mapping needs to be set up, using the debug_ll_io_init() helper
function.

Current, the L2 cache and the mvebu-mbus drivers are initialized at
->init_early() time. However, at ->init_early() time, ioremap() only
works if a static I/O mapping has already been put in place. If it's
not the case, it tries to do a memory allocation with kmalloc() which
is not possible so early at this stage of the initialization.

Since we want to get rid of the static I/O mapping, we cannot
initialize the L2 cache driver and the mvebu-mbus driver so early. So,
we move their initialization to the ->init_time() level, which is
slightly later (so ioremap() works properly), but sufficiently early
to be before the call of the ->smp_prepare_cpus() hook, which creates
an address decoding window for the BootROM, which requires the
mvebu-mbus driver to be properly initialized.

Now that the coherency_get_cpu_count() function no longer requires a
very early mapping of the coherency unit registers, we can avoid the
hardcoded virtual address in coherency.c. However, the coherency
features are still used quite early, so we need to do the of_iomap()
early enough, at the ->init_timer() level, so we have the call of
coherency_init() at this point.

Unfortunately, at ->init_timer() time, it is not possible to register
a bus notifier, so we add a separate coherency_late_init() function
that gets called as as postcore_initcall(), when bus notifiers are
available.

The ->smp_init_cpus() function is called very early during boot, at a
point where dynamic I/O mappings are not yet possible. However, in the
Armada 370/XP implementation of this function, we have to get the
number of CPUs. We used to do that by accessing a hardware register,
which requires relying on a static I/O mapping set up by
->map_io(). Not only this requires hardcoding a virtual address, but
it also prevents us from removing the static I/O mapping.

So this commit changes the way used to get the number of CPUs: we now
use the Device Tree, which is a representation of the hardware, and
provides us the number of available CPUs. This is also more accurate,
because it potentially allows to boot the Linux kernel on only a
number of CPUs given by the Device Tree, instead of unconditionally on
all CPUs.

As a consequence, the coherency_get_cpu_count() function becomes no
longer used, so we remove it.
