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.

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)

226a6ec311 Blackfin arch: sram: use 'unsigned long' for irqflags
Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.

The patch was generated using the Coccinelle semantic patch framework.

- Disable all bits in SIC_IWR unless we are going into a real (DPMC)
   power saving mode. Any Interrupt can wake the core form it's idle state.

 - Remove deep sleep mode as it is not going to be used anywhere:
   We support sleep, sleep deeper and hibernate.
