ada591d2a0 mpc8[56]xx: Put localbus clock in sysinfo and gd
Currently MPC85xx and MPC86xx boards just calculate the localbus frequency
and print it out, but don't save it.

This changes where its calculated and stored to be more consistent with the
CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock.

The localbus frequency is added to sysinfo and calculated when sysinfo is
set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are.

get_clocks() copies the frequency into the global data, as the other
frequencies are, into a new field that is only enabled for MPC85xx and
MPC86xx.

checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency
from sysinfo, like the other frequencies, instead of calculating it on the
spot.

a5d212a263 mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

75b9d4ae0d Pass in tsec_info struct through tsec_initialize
The tsec driver contains a hard-coded array of configuration information
for the tsec ethernet controllers.  We create a default function that works
for most tsecs, and allow that to be overridden by board code.  It creates
an array of tsec_info structures, which are then parsed by the corresponding
driver instance to determine configuration.  Also, add regs, miiregs, and
devname fields to the tsec_info structure, so that we don't need the kludgy
"index" parameter.

3473ab7372 Feed the watchdog in u-boot for 8610 board.
The watchdog on 8610 board is enabled by setting sw[6]
to on. Once enabled, the watchdog can not be disabled
by software. So feed the dog in u-boot is necessary for
normal operation.

dd35479a50 Add mechanisms for CPU and board-specific Ethernet initialization
This patch is the first step in cleaning up net/eth.c, by moving Ethernet
initialization to CPU or board-specific code.  Initial implementation is
only on the Freescale TSEC controller, but others will be added soon.

1ced121600 Update SVR numbers to expand support
FSL has taken to using SVR[16:23] as an SOC sub-version field.  This
is used to distinguish certain variants within an SOC family.  To
account for this, we add the SVR_SOC_VER() macro, and update the SVR_*
constants to reflect the larger value.  We also add SVR numbers for all
of the current variants.  Finally, to make things neater, rather than
use an enormous switch statement to print out the CPU type, we create
and array of SVR/name pairs (using a macro), and print out the CPU name
that matches the SVR SOC version.

13f5433f70 86xx: Convert sbc8641d to use libfdt.
This is the proper fix for a missing closing brace in the function
ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com.
The ft_cpu_setup() function in mpc8641hpcn.c should have been
removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
but was missed.  Only, the sbc8641d was nominally still using it.
It all got ripped out, and the funcality that was in ft_board_setup()
was refactored to remove the CPU portions into the new file
cpu/mpc86xx/fdt.c instead.  Make sbc8641d use this now.

Based loosely on an original patch from joe.hamman@embeddedspecialties.com

bd7851ce1e mpc86xx; Write MAC address to mac-address and local-mac-address
Some device trees have a mac-address property, some have local-mac-address,
and some have both.  To support all of these device trees, ftp_cpu_setup()
should write the MAC address to mac-address and local-mac-address, if they
exist.

3d98b85800 Add PIXIS FPGA support for MPC8641HPCN board.
Move the 8641HPCN's PIXIS code to the new directory
board/freescale/common/ as it will be shared by
future boards not in the same processor family.

Write a "pixis_reset" command that utilizes the FPGA
reset sequencer to support alternate soft-reset options
such as using the "alternate" flash bank, enabling
the watch dog, or choosing different CPU frequencies.

Add documentation for the pixis_reset to README.mpc8641hpcn.
