Defining these macros way down in arch/sh/.../irq.c doesn't cause
kernel/irq/generic-chip.c to use them. As far as I can tell this code
has no effect.

Currently, these I/O accessors always assume little endian 32-bit
registers (readl/writel). On some systems the IRQ registers need to be
accessed in BE mode or using 16-bit loads/stores, so we will provide a
way to override the default behavior.

Some chips, such as BCM6328, only require bcm7120-l2. Some BCM7xxx STB
configurations only require brcmstb-l2. Treat them as two separate
entities, and update the mach-bcm dependencies to reflect the change.

This effectively converts the __raw_ accessors to the non-__raw_
equivalents. To handle BE, we pass IRQ_GC_BE_IO, similar to what was
done in irq-bcm7120-l2.c.
Since irq_reg_writel now takes an irq_chip_generic argument, writel must
be used for the initial hardware reset in the probe function.
This mask should have been 0x_, not 0x0fff_.
The change should not have an effect on current users (STB) because bits
31:27 are unused.

This check may be prone to race conditions, e.g.
1) Some external event (e.g. GPIO level) causes an IRQ to become pending
2) Peripheral asserts the L2 IRQ
3) CPU takes an interrupt
4) The event from #1 goes away
5) bcm7120_l2_intc_irq_handle() reads back a 0 status
Unlike the hardware supported
Most implementations of the bcm7120-l2 controller only have a single
32-bit enable word + 32-bit status word. But some instances have added
more enable/status pairs in order to support 64+ IRQs (which are all
ORed into one parent IRQ input). Make the following changes to allow
the driver to
On BE MIPS systems this needs to use the new IRQ_GC_BE_IO gc_flag. In
all other cases it will use the standard readl/writel accessors.
The initial irq_fwd_mask setup runs before gc is initialized, so it
is unchanged for now. This could potentially be a problem on an ARM
system that boots in LE
A couple of accesses to IRQEN (base+0x00) just used base directly, so
they would break if IRQEN ever became nonzero. Make sure that all
reads/writes specify the register offset constant.

The cached value already incorporates irq_fwd_mask, and was saved the

Pass in the irq_chip_generic struct so we can use different readl/writel
settings for each irqchip driver, when appropriate. Compute
(gc-reg_base + reg_offset) in the helper function because this is pretty
much what all callers want to do anyway.
