Mike Frysinger fa48f84a8c Blackfin: unify memory map headers
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.

Graf Yang a427293f84 Blackfin: bf518f-ezbrd: fix SPI CS for SPI flash
The SPI flash on the BF518F-EZBRD board is actually hooked up to CS2,
not CS1, so make sure the resources are correct.

Both software emulated and hardware based CTS and RTS are enabled in

The CTS RTS PIN connection on BF548 UART port is defined as a modem
device not as a host device.  In order to test it under Linux, please
nake a cross UART cable to exchange CTS and RTS signal.

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.
