This is a generic approach to port u-boot for nios2 boards.
You may find the usage of this approach on the nioswiki,
http://nioswiki.com/DasUBoot
A fpga parameter file, which contains base address information
and drivers declaration, is generated from Altera's hardware system
description sopc file using tools.
The example fpga parameter file is compatible with EP1C20, EP1S10
and EP1S40 boards. So these boards can be removed after this commit.
Though epcs controller is removed to cut the dependency of altera_spi
driver.

This patch adds an option to bypass output waiting when there
is no jtag connection. This allows the jtag uart work similar
to a serial uart, ie, boot even without connection.
This option is enabled with CONFIG_ALTERA_JTAG_UART_BYPASS

Extend mpc512x serial driver to support multiple PSC ports.
Subsequent patches for PDM360NG board support make use of this
functionality by defining CONFIG_SERIAL_MULTI in the board config
file. Additionally the used PSC devices are specified by defining
e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6.
Support for PSC devices other than 1, 3, 4 and 6 is not added
by this patch because these aren't used currently. In the future
it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and
INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c.
Additionally you have to add code for registering added
devices in serial_initialize() in common/serial.c.

Subsequent patch extends mpc512x serial driver to support
multiple PSC ports. The driver will provide an uninit()
function to stop the serial controller and to disable the
controller's clock. Adding uninit() entry to struct serial_device
allows disabling the serial controller after usage of
a stdio serial device.
This patch adds uninit() entry to the struct serial_device
and fixes initialization of this structure in the code
accordingly.

The 440SPe Rev. A is quite old and newer 440SPe boards don't need support
for this CPU revision. Since removing support for this older version
simplifies the creation for newer U-Boot ports, this patch now enables
440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By
defining this in the board config header, Rev. A will still be supported.
Otherwise (default for newer board ports), Rev. A will not be supported.
