Mike Frysinger de55aa33ca Blackfin: bf54x: re-enable anomaly 05000353 for all revs
Even though the anomaly sheet says that the the bootrom is fixed, tests
have shown that the fix itself does not handle all cases.  So until we
get a ROM update, assume the reset code is still broken and we need to
handle things ourselves.

Mike Frysinger 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.

steven miao 55835175a0 Blackfin: bf54x: add kconfig for UART2/3 DMA channel assignments
The BF54x lacks dedicated DMA channels for the UART peripherals and need
to be muxed between others.  So add a kconfig option so people can select
which channels the UARTs will use so they can pick between SPORTs and the
less commonly used EPPI/PIXC peripherals.

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.

Hema Kalliguddi fcf173e451 usb: musb: add names for IRQs in structure resource
Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.

Such database, might not have resources at
the expected order by the current drivers.

While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.

Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.

Rename h/w IRQ flags handling functions to be in line with what is expected for

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.
