ab48ca1a66 ppc/p4080: Fix synchronous frequency calculations
When DDR is in synchronous mode, the existing code assigns sysclk
frequency to DDR frequency.  It should be synchronous with the platform
frequency.  CPU frequency is based on platform frequency in synchronous
mode.

Also fix:

* Fixes the bit mask for DDR_SYNC (RCWSR5[184])
* Corrects the detection of synchronous mode.

2ebdb9a9d7 mpc5121: add common post_word_load/store code
Add common post_word_load/post_word_store routines
for all mpc5121 boards. pdm360ng board POST support
added by subsequent patch needs them.

DDR Local Access Window and determine the RAM size.
Fix DDR LAW afterwards using detected RAM size.

e3b28e6732 mpc512x: add multi serial PSC support
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.

fbb0030e38 serial: struct serial_device: add uninit() entry for drivers
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.

dfe812c744 mpc83xx: use "A" nomenclature only on mpc834x and mpc836x families
marketing didn't extend their postpend-with-an-A naming strategy
on rev.2's and higher beyond the first two 83xx families.  This
patch stops us from misreporting we're running e.g., on an MPC8313EA,
when such a name doesn't exist.

27ef578df7 mpc83xx: Use CONFIG_FSL_ESDHC to enable sdhc clk
Enable eSDHC Clock based on generic CONFIG_FSL_ESDHC define
instead of a platform define. This will enable all the 83xx
platforms to use sdhc_clk based on CONFIG_FSL_ESDHC.  It's
the same patch as commit 6b9ea08c50
for the ppc/85xx.

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.
