Mike Frysinger 9466a0510a Blackfin: bf538: pull gpio/port logic out of core hibernate paths
Re-architect how we save/restore the gpio/port logic that only pertains
to bf538/bf539 parts by pulling it out of the core code paths and pushing
it out to bf538-specific locations.

Mike Frysinger 63917efc4f Blackfin: mach/bfin_serial_5xx.h: punt now-unused header
Now that the serial code has been unified in bfin_serial.h, and the
Blackfin UART driver pushed its resources to the boards files, we
don't need these headers anymore.

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

The BF561 header also had a lot of unused CONFIG_DEF_xxx defines, so
punt them all.

Mike Frysinger a2ce077ab3 Blackfin: drop asm/irq.h include from mach headers
These were only included because of the irq handling of the PLL funcs,

Mike Frysinger 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.

David Howells 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.

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

This is because the #ifdef's in bfin_serial_5xx.h are messed up. More
specifically, they add/remove the uart_{rts,cts}_pin fields in
bfin_serial_resources based on whether the particular port has rts/cts enabled,
as opposed to when either port has it enabled.
