      ARM: S3C24XX: add handle_irq function · 17453dd2
      由 Heiko Stuebner 提交于 
      This removes the dependency on static irq mappings for basic irq handling
and makes the s3c24xx entry-macro.S obsolete.

Also the interrupts of the second full interrupt controller on the s3c2416
are really handled now, which was forgotten when adding them.

The handling itself does the same as the previous assembler-code in that
it tries to get the interrupt offset from the offset register first and
if that produces wrong results manually searches for the interrupt bit
in the pending register value. It also saves the historic comment which
explains the reason behind this.

      ARM: S3C24XX: move s3c24xx_init_irq to s3c2410_init_irq · f182aa1d
      由 Heiko Stuebner 提交于 
      The s3c24xx_init_irq function that was the base for all irq inits
is now only used to initialize the real s3c2410 irqs.

Therefore rename it and also move its declaration from plat/cpu.h
to common.h

The eint declaration is used by the vast majority of the SoCs and
gets therefore placed outside any ifdefs.

      ARM: S3C24XX: fix irq parent check · 0fe3cb1e
      由 Heiko Stuebner 提交于 
      The current parent_irq check checks for a value != 0. This does of course
not work when the parent irq sits in the bit 0 of the parent register.
This only affects the eint0 interrupt of the s3c2412.

To fix this behaviour, check for the presence of a parent_intc in the
structure. In an s3c24xx interrupt controller either all interrupts have
parent interrupts or none have, so if a parent controller is available
the parent_irq value always points to a parent_irq.

      ARM: S3C24XX: fix redundant checks in the irq mapping function · 502a2989
      由 Heiko Stuebner 提交于 
      The check during the parent handling itself was wrong, as it should have
checked for parent_irq_data.

The interrupt controller structs always contain an irq_data array with 32
entries and the only possible error could be a parent_irq assignment of >31.

As this would point to outside the irq_data array this could contain
anything including non-NULL values. Therefore correct this to check
the parent_irq value to be in the right range.

With the same explanation of a valid interrupt controller always having a
full irq_data array, the topmost irq_data check in s3c24xx_irq_map
can also go away.

Finally the mapping function is only called thru the irq_domain ops, in
which case the intc struct is already successfully created, so there is
no need to check for it again.
