71bd860cce mpc83xx: don't shift pre-shifted ACR, SPCR, SCCR bitfield masks in cpu_init.c
commit c7190f028f "mpc83xx:
retain POR values of non-configured ACR, SPCR, SCCR, and LCRR
bitfields" incorrectly shifted <register>_<bitfield> (e.g.
ACR_PIPE_DEP) values that were preshifted by their
definition in mpc83xx.h.

this patch removes the unnecessary shifting for the newly
utilized mask values in cpu_init.c, and prevents seemingly
unrelated symptoms such as an mpc8379erdb board from
locking up whilst performing a networking operation,
e.g. a tftp.

a4bfc4cc46 mpc83xx: fix NAND bootstrap too big error
commit 167cdad137 "SERIAL: Enable
port-mapped access" inadvertently broke 83xx nand boards by
converting NS16550_init to use io accessors, which expanded
the size of the generated code.

this patch fixes the problem by removing icache functions from
the nand builds, which somewhat follows commit
1a2e203b31 "mpc83xx: turn on icache
in core initialization to improve u-boot boot time"

e4a95d112e powerpc: Consolidate bootcount_{store|load} for PowerPC
This patch consolidates bootcount_{store|load} for PowerPC by
implementing a common version in arch/powerpc/lib/bootcount.c. This
code is now used by all PowerPC variants that currently have these
functions implemented.

The functions now use the proper IO-accessor functions to read/write the
values.

This code also supports two different bootcount versions:

a) Use 2 separate words (2 * 32bit) to store the bootcounter
b) Use only 1 word (2 * 16bit) to store the bootcounter

Version b) was already used by MPC5xxx.

7e1afb62a7 ppc: Split MPC83xx SERDES code from MPC85xx/MPC86xx/QorIQ
The MPC83xx SERDES control is different from the other FSL PPC chips.
For now lets split it out so we can standardize on interfaces for
determining of a device on SERDES is configured.

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.
