f1a1d52508 blackfin: anomaly: add anomaly 16000030 for bf5xx
Drivers common to both bf5xx and bf60x chip families may use this anomaly id.
So add it to bf5xx header files also.

65cd3b5362 Blackfin: bf51x: fix alternative portmux options
The BF51x's alternative portmux Kconfig options were copy & pasted from
the BF52x, but never tweaked to reflect it.  So drop the old options as
they were never used (and were simply wrong), and add the BF51x specific
pieces to the Kconfig and header.

fcb243918f Blackfin: bf51x: fix up RSI_PID# MMR defines
Looks like the copying of MMR defines from the SDH block missed updating
the addresses of the RSI_PID# registers.  So tweak them to reflect the

3dd666067d Blackfin: clean up style in irq defines
These files had a lot of whitespace damage, mostly due to copying and

58ee0d3bb1 Blackfin: punt unused HDMA masks
No code uses these, and the short define names are polluting the global
namespace where they collide with things like common irq files.  So just
punt the damned things.  If in the future we need HDMA support, we can
make a standalone header for these things.

53ee582654 Blackfin: bf51x/bf52x: drop redundant "base" def/cdef header
The defBF512.h header exists only to include defBF51x_base.h, and it is
the only place where defBF51x_base.h is included.  So move the contents
of the defBF51x_base.h header into the defBF512.h header.

Same situation for the other def/cdef pairs.

1a5c226528 Blackfin: clean up mach header includes
The main asm/blackfin.h header will pull in mach/blackfin.h to get
all the fun Blackfin defines.  So having any of the sub-mach headers
trying to include asm/blackfin.h makes no sense -- punt it.

The mach/blackfin.h header takes care of including the part-specific
def headers which in turn will include any other needed def file.
Similarly, it takes care of pulling in the part-specific cdef header.
So move this logic out of the blackfin.h when necessary.

Further, make sure the cdef headers do not waste time including the
def headers again.

Since all parts need the common def/cdef headers, move this logic
out of the part-specific headers and into the mach/blackfin.h file.

Finally, we need to split the BF539 def header since the BF538 does
not have MXVR and we don't want to expose those MMRs.

So now all parts should have the same behavior:
	mach/blackfin.h
		asm/def_LPBlackfin.h
		part-specific def.h
		if ! asm
			asm/cdef_LPBlackfin.h
			part-specific cdef.h
And the sub def/cdef headers only tail into what they need.

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

3b139cdb37 Blackfin: Rename IRQ flags handling functions
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.

aec59c9113 Blackfin: add support for the on-chip MAC status interrupts
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.

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
