When compile-testing on arm:
arch/sh/include/cpu-sh4/cpu/sh7786.h: In function ‘sh7786_mm_sel’:
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:21: warning: passing argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [-Wint-conversion]
return __raw_readl(0xFC400020) & 0x7;
^~~~~~~~~~

from drivers/pinctrl/sh-pfc/pfc-sh7786.c:15:
arch/arm/include/asm/io.h:113:21: note: expected ‘const volatile void *’ but argument is of type ‘unsigned int’

static inline u32 __raw_readl(const volatile void __iomem *addr)
^~~~~~~~~~~
__raw_readl() on SuperH is a macro that casts the passed I/O address to
the correct type, while the implementations on most other architectures
expect to be passed the correct pointer type.
Add an explicit cast to fix this.
Note that this also gets rid of a sparse warning on SuperH:
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: warning: incorrect type in argument 1 (different base types)
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: expected void const volatile [noderef] <asn:2>*<noident>
arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: got unsigned int

The SH7786 has different physical memory layout configurations,
configurable through the MMSELR register. The configuration is
typically defined by the bootloader, so Linux generally doesn't care.
Except that depending on the configuration, some PCI MEM areas may or
may not be available. This commit adds a helper function that allows
to retrieve the current physical memory layout configuration. It will
be used in a following patch to exclude unusable PCI MEM areas during
the PCI initialization.

The port E, G and J GPIOs don't match the SoC datasheet (they seem to
have been copied from the SH7785). Fix them.

This adds preliminary support for the SH7786 CPU subtype.
While this is a dual-core CPU, only UP is supported for now. L2 cache
support is likewise not yet implemented.
More information on this particular CPU subtype is available at:
