22b6dbc169 MPC85xx: Add MPC8569 CPU support
There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of
LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage,
then invalidate it after LBCR bit 13 is set.

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.

446c381e3e mpc8568: Double local bus clock divider
The clock divider for the MPC8568 local bus should be doubled, like the
other newer MPC85xx chips.

Since there are now more chips with a 2x divider than a 1x, and any new
85xx chips will probably be 2x, invert the sense of the #if so that it
lists the 1x chips instead of the 2x ones.

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.

4dbdb7681e 85xx: expose cpu identification
The current cpu identification code is used just to return the name
of the processor at boot.  There are some other locations that the name
is useful (device tree setup).  Expose the functionality to other bits
of code.

Also, drop the 'E' suffix and add it on by looking at the SVR version
when we print this out.  This is mainly to allow the most flexible use
of the name.  The device tree code tends to not care about the 'E' suffix.

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.
