The array of pointers is never written, so constify it.

Use the same naming convention for DMA traffic MMRs (most were legacy
anyways) so we can avoid useless ifdef trees.
Same goes for MDMA names -- this actually allows us to undo a bunch of
ifdef redirects that existed for this purpose alone.

Each Blackfin port has been duplicating UART structures and defines when
there really is no need for it. So start a new bfin_serial.h header to
unify all these pieces and give ourselves a fresh start.

Move all the pin settings out of the Kconfig and into the platform
resources (MII vs RMII). This clean up also lets us push out the
phy settings so that board porters may control the layout.

The RX/TX address is always the same regardless of the size of the access.
That means there is no dedicated "16bit" or "32bit" MMR. Trying to use
these currently leads to compile errors. So change everything to use the
right MMR define.

The num_chipselect field for on-chip Blackfin SPI buses is supposed to
be 1 larger than the number of actual CSs available. This is because
the hardware starts counting at 1 and not 0. There is a field for "CS0",
but it is marked as "reserved" everywhere.

Now that the common header defines everything and the SPI drivers are
using it, we can drop these duplicated global namespace polluters.

Rename h/w IRQ flags handling functions to be in line with what is expected for
the irq renaming patch. This renames local_*_hw() to hard_local_*() using the
following perl command:
perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"`
and then fixing up asm/irqflags.h manually.
Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both
return the flags rather than passing it through the argument list.

Split the PLL control code from the Blackfin machine-specific cdef headers so
that the irqflags functions can be renamed without incurring a header loop.

The standard short name for control is CTL and not CTRL. Use TWI0_xxx
even on parts that only have one TWI bus to keep things simple. Drop
all the cdef helpers since the bus driver takes care of everything.

Even though the PH8 pin is only internal to the processor packaging, it
can be controlled like any other GPIO pin. Now that we have a proper GPIO
define, we can fix the SPI0 CS4 define for the internal SPI flash.

This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in
phylib. New Interrupts added:
IRQ_MAC_PHYINT /* PHY_INT Interrupt */
IRQ_MAC_MMCINT /* MMC Counter Interrupt */
IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */
IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */
IRQ_MAC_WAKEDET /* Wake-Up Interrupt */
IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */
IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */
IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */
On BF537/6 the implementation is not straight forward since there are now
two chained chained_handlers. A cleaner approach would have been to add
latter IRQs to the demux of IRQ_GENERIC_ERROR.

Rather than keeping the pins in the actual driver and worrying about a
mess of Kconfig options, declare all the desired pin resources in the
boards file. This lets people easily select the specific pins/ports for
the normal emulated UART as well as GPIOs for CTS/RTS.

While we're moving the BF54x code, have the BF54xM variants select the
normal BF54x values so that the rest of the Kconfig tree doesn't need to
check the BF54xM variant everytime it wants to check the BF54x.

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.
It also removes:
- verbose GPL text(refer to the top level ./COPYING file)
- file names (you are looking at the file)
- bug url (it's in the ./MAINTAINERS file)
- "or later" on GPL-2, when we did not have that right
It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Many aspects of the Blackfin memory map is exactly the same across all
variants. Rather than copy and paste all of these duplicated values in
each header, unify all of these into the common Blackfin memory map header
file. In the process, push down BF561 SMP specific stuff to the BF561
specific header to keep the noise down.
