Add support for UART serial ports using a Freescale QUICCEngine. Update booting-without-of.txt to define new properties for a QE UART node. Update the MPC8323E-MDS device tree to add UCC5 as a UART. Update the QE library to support slow UCC devices and modules. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* To enable external serial I/O on a Freescale MPC 8323 SYS/MDS board, do
|
|
* this:
|
|
*
|
|
* 1) On chip U61, lift (disconnect) pins 21 (TXD) and 22 (RXD) from the board.
|
|
* 2) Solder a wire from U61-21 to P19A-23. P19 is a grid of pins on the board
|
|
* next to the serial ports.
|
|
* 3) Solder a wire from U61-22 to P19K-22.
|
|
*
|
|
* Note that there's a typo in the schematic. The board labels the last column
|
|
* of pins "P19K", but in the schematic, that column is called "P19J". So if
|
|
* you're going by the schematic, the pin is called "P19J-K22".
