12e431b277 dm: serial: Add driver model support for ns16550
Add driver model support so that ns16550 can support operation both with
and without driver model.

The driver needs a clock frequency so cannot stand alone unfortunately. The
clock frequency must be provided by a separate driver.

d57dee5787 serial: nsl16550: add hw flow control support
keystone serial hw support hw flow control. This patch
enables hw flow control for keystone EVMs as an optional
feature based on CONFIG_SERIAL_HW_FLOW_CONTROL.

79df1208ee ns16550: change to allow 32 bit access to registers
If CONFIG_SYS_NS16550_MEM32 is defined then 32 bit memory
mapped access will be used to read/write the uart registers.

This is especially useful for SoC devices that implement 16550
compatible uarts but that have peripheral access width constraints.

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

453c0d7558 include/ns16550.h: Unify structure declaration for registers
Instead of special casing the different access patterns, use common
code with light macros sprinkled in to accomodate for the different
layouts of the register structure.

Note that this also changes the types of the registers for the
"positively packed (>1)" cases.  As the registers truly are unsigned
chars, this is surely the Right Thing, but it is a semantic change.
Note that for this case depending on the endianness on the bus, we may
see a change of behaviour.

Fix problems introduced in commit
7b5611cdd1 [inka4x0: Add hardware
diagnosis functions for inka4x0] which redefined MSR_RI which is
already used on PowerPC systems.

Also eliminate redundant definitions in ps2mult.h.  More cleanup will
be needed for other redundant occurrences though.
