Graf Yang b3ef5aba64 Blackfin Serial Driver: Fix bug - ircp fails on sir over Blackfin UART
We now use the sir_dev/irtty_sir/uart/bfin_serial drivers framework
to monitor the TX status.

Mike Frysinger c9607ecc6e Blackfin Serial Driver: move common variables out of serial headers and into the serial driver
move common variables out of serial headers and into the serial driver and
rename "nr_ports" to "nr_active_ports" so as to easily differentiate
between BFIN_UART_NR_PORTS (the # of available) and nr_ports (the # of enabled)

Don't write conflicting data to EBIU_SDBCTL after the SDRAM is
configured. This can cause data corruption, since we might change SDRAM
row and column addressing modes.

Laurent Pinchart da3854fc9f DM9000: Fixup blackfin after removing 2 resource usage
The dm9000 driver accepts either 2 or 3 resources to describe the platform
devices. The 2 resources case abuses the ioresource mechanism by passing
ioremap()ed memory through the platform device resources. This patch removes
converts boards that were using it to the 3 resources scheme.
