In order to update the LMA for each section, according to
CONFIG_XIP_BASE, this patch uses the preprocessor to change
the arguments passed to the AT keyword. Each LMA is updated
to that symbol's physical address.
The text section is aligned to a page so that the ELF
header at the beginning of XIP_
Nothing is loaded at the usual spot for .text, starting at
CONFIG_PHYSICAL_START, so we don't reserve it. Additionally,
the physical address of the _text isn't going to be physically
contiguous with _data.

If the kernel tries to create an identity region for a memory range
that spans the kernel text, split it into two pieces, skipping the
text section. Otherwise, this will setup the standard text mapping,
which will point to the normal RAM location for text instead of the
XIP_BASE location.

e820_add_kernel_range() checks whether the kernel text is present
in the e820 map, and marked as usable RAM. If not, it modifies
the e820 map accordingly.
For XIP, that is unnecessary since the kernel text won't be loaded
in RAM.

Make the tpm_infineon driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct pnp_driver.
This allows the driver to use tpm_pm_suspend() as its suspend

This also f

Tegra210 has an extra bank of peripheral clock registers. Add it to the
generic peripheral clock code.
