Set IVPR to kenrel entry point in second core boot page
Assuming the OSes exception vectors start from the base of kernel address, and
the kernel physical starting address can be relocated to an non-zero address.
This patch enables the second core to have a valid IVPR for debugger before
kernel setting IVPR in CAMP mode. Otherwise, IVPR is 0x0 and it is not a valid
value for second core which runs kernel at different physical address other
than 0x0.

mpc8[56]xx: Put localbus clock in device tree
Export the localbus frequency in the device tree, the same way the CPU, TB,
CCB, and various other frequencies are exported in their respective device
tree nodes.
Some localbus devices need this information to be programed correctly, so
it makes sense to export it along with the other frequencies.
Unfortunately, when someone wrote the localbus dts bindings, they didn't
bother to define what the "compatible" property should be. So it seems no
one was quite sure what to put in their dts files.
Based on current existing dts files in the kernel source, I've used
"fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all
of the 85xx devices, and are looked for by the Linux code. The eLBC is
apparently not entirely backward compatible with the pq3 LBC and so eLBC
equipped platforms like 8572 won't use pq3-localbus.
For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems
and is also looked for by the Linux code. On MPC8641, I've also used
"fsl,mpc8641-localbus" as it is also commonly used in dts files, some of
which don't use "fsl,elbc" or any other acceptable name to match on.

NAND FSL elbc: Use virt_to_phys to determine which bank is in use
The current code that determines which bank/chipselect is used for a

The proper way to handle this is to use the virt_to_phys() and

of these structures also not word aligned.
