Mike Frysinger def282d615 Blackfin: punt duplicated CAN MMRs
Now that there's a common header with everything unified, drop the defines
from the global namespace.  Pollution sucks.

Sonic Zhang df5de26130 Blackfin: move SPORT UART resources to boards files
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.

Michael Hennerich 621dd24743 Blackfin: bf538: add support for extended GPIO banks
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as
the other ports on the part and the same way as all other Blackfin parts.
The MMRs are programmed slightly different and they cannot be used to
generate interrupts or wakeup a sleeping system.  Since these guys don't
fit into the existing code, create a simple gpiolib driver for them.

Robin Getz 96f1050d3d Blackfin: mass clean up of copyright/licensing info
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).

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.

This patch fixed this.
