T1040 and it's variants provide "Single Oscillator Source" Reference Clock Mode.
In this mode, single onboard oscillator(DIFF_SYSCLK) can provide the reference clock
(100MHz) to the following PLLs:
• Platform PLL
• Core PLLs
• USB PLL
• DDR PLL, etc
The cfg_eng_use0 of porsr1 register identifies whether the SYSCLK (single-ended) or
DIFF_SYSCLK (differential) is selected as the clock input to the chip.
get_sys_info has been enhanced to add the diff_sysclk so that the
various drivers can be made aware of ths diff sysclk configuration and
act accordingly.
Other changes:
-single_src to ddr_refclk_sel, as it is use for checking ddr reference clock
-Removed the print of single_src from get_sys_info as this will be
-printed whenever somebody calls get_sys_info which is not appropriate.
-Add print of single_src in checkcpu as it is called only once during initialization

85xx, 86xx PowerPC folders have code variables with CamelCase naming conventions.
because of this code checkpatch script generates "WARNING: Avoid CamelCase".
Convert variables name to normal naming convention and modify board, driver
files with updated the new structure.

Starting from QMan3.0, the QMan clock cycle needs be exposed so that the kernel
driver can use it to calculate the shaper prescaler and rate.

The means to determine the core, bus, and DDR frequencies are completely
new on CoreNet style platforms. Additionally on p4080 we can have
different frequencies for FMAN and PME IP blocks. We need to keep track
of the FMAN & PME frequencies since they are used for time stamping
capabilities inside each block.

The number of CPUs are getting detected dynamically by checking the
processor SVR value. Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.
This can help to use the same u-boot image across the platforms.
Also revamped and corrected few Freescale Copyright messages.

This patch updates e500 freqProcessor to array based on CONFIG_NUM_CPUS,
and prints each CPU's frequency separately. It also fixes up each CPU's
frequency in "clock-frequency" of fdt blob.

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.

The old macros made it difficult to know what WIMGE and perm bits
were set for a TLB entry. Actually use the bit masks for these items
since they are only a single bit.
Also moved the macros into mmu.h out of e500.h since they aren't specific
to e500.
