40d1f00482 sh: Fix up uncached offset for legacy 29-bit mode.
The uncached_start was being set up properly for 32-bit but managed to
break 29-bit in the process, fix it up.

0272282f7c sh: Convert sh to use read/update_persistent_clock
This patch converts the sh architecture to use the generic
read_persistent_clock and update_persistent_clock interfaces, reducing
the amount of arch specific code we have to maintain, and allowing for
further cleanups in the future.

... so the "sh_debugfs_root" is already available. Previously it

b07f6b327e sh: Fix up flush_cache_vmap() on SMP.
flush_cache_all() uses broadcast IPIs, so we can't wrap in to that when
IRQs are disabled. The local cache flush manages to do what we need here
anyways, so just switch to that.

281983d6ff sh: fix up MMU reset with variable PMB mapping sizes.
Presently we run in to issues with the MMU resetting the CPU when
variable sized mappings are employed. This takes a slightly more
aggressive approach to keeping the TLB and cache state sane before
establishing the mappings in order to cut down on races observed on
SMP configurations.

At the same time, we bump the VMA range up to the 0xb000...0xc000 range,
as there still seems to be some undocumented behaviour in setting up
variable mappings in the 0xa000...0xb000 range, resulting in reset by the
TLB.

09e1172317 sh: establish PMB mappings for NUMA nodes.
In the case of NUMA emulation when in range PPNs are being used for
secondary nodes, we need to make sure that the PMB has a mapping for it
before setting up the pgdat. This prevents the MMU from resetting.

a1042aa248 sh: check for existing mappings for bolted PMB entries.
When entries are being bolted unconditionally it's possible that the boot
loader has established mappings that are within range that we don't want
to clobber. Perform some basic validation to ensure that the new mapping
is out of range before allowing the entry setup to take place.

90e7d649d8 sh: reworked dynamic PMB mapping.
This implements a fairly significant overhaul of the dynamic PMB mapping
code. The primary change here is that the PMB gets its own VMA that
follows the uncached mapping and we attempt to be a bit more intelligent
with dynamic sizing, multi-entry mapping, and so forth.

027811b9b8 dmaengine: shdma: convert to platform device resources
The shdma dmaengine driver currently uses numerous macros to support various
platforms, selected by ifdef's. Convert it to use platform device resources and
lists of channel descriptors to specify register locations, interrupt numbers
and other system-specific configuration variants. Unavoidably, we have to
simultaneously convert all shdma users to provide those resources.

now being able to override their own settings via prctl().

7c1b2c6890 sh: allow alignment fault mode to be configured at kernel boot.
Follow the ARM change, which is what our alignment helpers are based on
in the first place.

3b7a17fcda resource/PCI: mark struct resource as const
Now that we return the new resource start position, there is no
need to update "struct resource" inside the align function.
Therefore, mark the struct resource as const.

b26b2d494b resource/PCI: align functions now return start of resource
As suggested by Linus, align functions should return the start
of a resource, not void. An update of "res->start" is no longer
necessary.

16afc9fb02 sh: sh7724: Update FSI/SPU2 clock
When FSI and Network (= NFS file system) were used at the same time,
the I/O of FSI was unstable.  This patch updates the SPU2 clock (which
is used for FSI) to solve this issue.  Special thanks to Jeremy.

6f26d19fce sh: always enable sh7724 vpu_clk and set to 166MHz on Ecovec
Update the sh7724 processor code to always enable vpu_clk.

On the Ecovec board, set the vpu_clk to 166 Mhz.

The 166MHz setting results in a divide-by-6 setup for
vpu_clk and improves the VPU performance compared to the
power-on-reset/bootloader configuration.

7be85c6eb4 sh: add sh7724 kick callback to clk_div4_table
This patch adds a ->kick() callback to clk_div4_table
and ties it into sh_clk_div4_set_rate(). A sh7724
specific kick function is also added that updates the
KICK bit whenever div4 clocks in FRQCRA and FRQCRB
have been set. Allows us to set the VPU clock.
