Geert Uytterhoeven 049d28048b sh: intc: Confine SH_INTC to platforms that need it
Currently the sh-intc driver is compiled on all SuperH and
non-multiplatform SH-Mobile platforms, while it's only used on a limited
number of platforms:
  - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5)
  - ARM: sh7372, sh73a0

Drop the "default y" on SH_INTC, make all CPU platforms that use it
select it, and protect all sub-options by "if SH_INTC" to fix this.

config INTC_USERIMASK
bool "Userspace interrupt masking support"
depends on (SUPERH && CPU_SH4A) || COMPILE_TEST
help
This enables support for hardware-assisted userspace hardirq
masking.
SH-4A and newer interrupt blocks all support a special shadowed
page with all non-masking registers obscured when mapped in to
userspace. This is primarily for use by userspace device
drivers that are using special priority levels.
If in doubt, say N.
config INTC_BALANCING
bool "Hardware IRQ balancing support"
depends on SMP && SUPERH && CPU_SHX3
help
This enables support for IRQ auto-distribution mode on SH-X3
SMP parts. All of the balancing and CPU wakeup decisions are
taken care of automatically by hardware for distributed
vectors.
If in doubt, say N.
config INTC_MAPPING_DEBUG
bool "Expose IRQ to per-controller id mapping via debugfs"
depends on DEBUG_FS
help
This will create a debugfs entry for showing the relationship
between system IRQs and the per-controller id tables.
If in doubt, say N.
