b135991a3c powerpc/mpc85xx: Add support for single source clocking
Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.

So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclock

DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
 normal clocking mode by DDR_Reference clock

-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
 single source clocking mode by DIFF_SYSCLK

Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

871a57bb81 common/cmd_bootm: extend do_bootm_vxworks to support the new VxWorks boot interface.
The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
description mechanism. For PowerPC, the boot interface conforms to
the ePAPR standard, which is:

   void (*kernel_entry)(ulong fdt_addr,
          ulong r4 /* 0 */,
          ulong r5 /* 0 */,
          ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
          ulong r8 /* 0 */, ulong r9 /* 0 */)

For ARM, the boot interface is:

   void (*kernel_entry)(void *fdt_addr)

51abee64ee powerpc/85xx: fix broken cpu "clock-frequency" property
When indexing freqProcessor[] we use the first
value in the cpu's "reg" property, which on
new e6500 cores IDs the threads.
But freqProcessor[] should be indexed with a
core index so, when fixing "the clock-frequency"
cpu node property, access the freqProcessor[]
with the core index derived from the "reg' property.
If we don't do this, last half of the "cpu" nodes
will have broken "clock-frequency" values.

8f9fe660fc powerpc/t4240: fix per pci endpoint liodn offsets
Update the code that builds the pci endpoint liodn
offset list so that it doesn't overlap with other
liodns and doesn't generate negative offsets like:

  fsl,liodn-offset-list = <0 0xffffffcd 0xffffffcf
                             0xffffffd1 0xffffffd3
                             0xffffffd5 0xffffffd7
                             0xffffffd9 0xffffffdb>;

The update consists in adding a parameter to the
function that builds the list to specify the base
liodn.
On PCI v2.4 use the old base = 256 and, on PCI 3.0
where some of the PCIE liodns are larger than 256,
use a base = 1024. The version check is based on
the PCI controller's version register.

06c14117c4 powerpc: convert makefiles to Kbuild style
Note:
arch/powerpc/cpu/mpc8260/Makefile is originally like follows:

    ---<snip>---
    START   = start.o kgdb.o
    COBJS   = traps.o serial_smc.o serial_scc.o cpu.o cpu_init.o speed.o \
    ---<snip>---
    COBJS-$(CONFIG_ETHER_ON_SCC) = ether_scc.o
    ---<snip>---
    $(LIB): $(OBJS)
            $(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)

The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'
is weird.
kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)

So,
    START   = start.o kgdb.o
shoud have been
    START   = start.o
    SOBJS   = kgdb.o

That is why this commit adds kgdb.o to obj-y, not to extra-y.

So this method is not flexible.

Now a function to get the address of a requested capability is added and used.
It can get the address dynamically by capability ID.
The step of this function:
	1. Read Status register in PCIe configuration space to confirm that

1b387ef55c SPDX: fix IBM-pibs license identifier
The SPDX License List version 1.19 now contains an official entry for
the IBM-pibs license.  However, instead of our suggestion "ibm-pibs",
the SPDX License List uses "IBM-pibs", with the following rationale:
"The reason being that all other SPDX License List short identifiers
tend towards using capital letters unless spelling a word.  I'd prefer
to be consistent to this end".

Change the license IDs to use the official name.

f62b123813 powerpc/mpc85xx: Fix the I2C bus speed error on p1022
The source clock frequency of I2C bus on p1022 is the platform(CCB)
clock, not CCB/2. The wrong source clock frequency leads to wrong
I2C bus speed setting. so, fixed it.
