All 32-bit SuperH processors currently go through __ioremap_mode()
and check for IO_TRAPPED and directly mapped segments. With this
patch we simplify the MMU less case with a pass through version of
 __ioremap_mode() which just returns the physical address.

The effects of this is change are:
 - fix non-MMU ioremap() of high address hardware blocks (sh7203 CMT)
 - make sure IO_TRAPPED is not selected

The device registration was accidentally omitted, add it back in. Do some
basic device probing as well, so this doesn't show up for platforms that

This patch moves the SuperH timer setup code from time_init()
to late_time_init(). Good things about this change:
 - interrupts: they are enabled at late_time_init()
 - mm: regular kmalloc() can be used at late_time_init()

Together with moving to late_time_init() this patch changes
the sh_cmt driver to always allocate with kmalloc(). This
simplifies the code a bit and also fixes section mismatches.

This patch improves the sh_cmt clocksource handling.

Currently the counter value is ignored in the case of
overflow. With this patch the overflow flag is read
before and after reading the counter, removing any
counter value and overflow flag mismatch issues.

The RTS7751R2D_1 boards only support 1MB of socket-mounted MBM29F040
flash, which we just leave alone as it's not terribly interesting.

This adds support for the s29gl256p on the r2d+ boards that makes a bit
more sense to expose to the user.

This patch is preparation for replacing all uses of ".head.text" or
".text.head" in the kernel with macros, so that the section name can
later be changed without having to touch a lot of the kernel.

Since some linker scripts do more complex things than referencing
HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the
actual name.

I've defined HEAD_TEXT_SECTION in a new header,
include/linux/section-names.h, so that this section name only needs to
appear in one place.  I anticipate creating similar macro structures
for a number of other section names.

The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections.  This requires renaming all magic sections with names
of the form ".text.foo".

Commit c7510859 ("PM/Hibernate: Wait for
SCSI devices scan to complete during resume") added a call to
scsi_complete_async_scans() to software_resume(), so that it waited for
the SCSI scanning to complete, but the call was added at a wrong place.

Namely, it should have been added after wait_for_device_probe(), which
is called only if the image partition hasn't been specified yet.  Also,
it's reasonable to check if the image partition is present and only wait
for the device probing and SCSI scanning to complete if it is not the
case.

Additionally, since noresume is checked right at the beginning of
software_resume() and the function returns immediately if it's set, it
doesn't make sense to check it once again later.
