Implement GPIO hotplugging via TMIO_MMC_HAS_COLD_CD for
AG5EVM SDHI0. This is possible now when INTCA is used for
IRQ triggering on sh73a0. Without INTCA IRQ support we are

Improve IRQ triggering support by making use of the macro
INTC_IRQ_PINS_32() for INTCA on sh73a0. Unfortunately it
is not as easy as just using the macro as-is, we need to
do mask and unmaks in the GIC but configure other bits
and ack in INTCA. Update GPIO IRQ mappings while at it.

This patch adds support for sh73a0 GPIO IRQs by making use
of the PFC GPIO IRQ feature. Only IRQ pins are supported
at this time. In the future when PINT interrupts also are
supported properly we can easily extend the table with such
information. Also, the sh73a0 is currently making use of
the GIC for external interrupt which is rather unflexible
when it comes to triggering configuration at this point.

Always use CS0 shadow area for NOR flash instead of regular CS0
memory area on ap4evb.
When booting from CS0 NOR Flash the regular CS0 memory area is
available, but when booting via USB the MASK ROM gets mapped to
0x0 which gets in the way for the NOR Flash. Always using CS0
shadow area works well for both NOR Flash boot and USB boot.

This patch add support for calling ctrl_alt_del() when the power button is
pressed for more than about 2 seconds on some freescale MPC83xx evaluation
boards and reference design.
The code uses a kthread to poll the CTRL_BTN bit each second.
Also change Kconfig entry of the driver to bool, as device's gpio
registration is broken when loading as module.
Tested on an MPC8315E RDB board.

This is listed as a requirement for Freescale CoreNet based devices (e.g
p4080ds with MPIC v4.x) after issuing a core reset to properly clear pending
interrupts.

The GE DTBs were not updated when the Gianfar driver was converted to an
of_platform_driver in commit b31a1d8b41513b96e9c7ec2f68c5734cef0b26a4. Update
the DTBs, adding the required TBI entries.

We need to ensure that MURAM is in a known and cleared out state before
using it as the bootloader could have utilized it from its own purposes
and left it in an unknown state.
If we don't clear it out we've seen issues with UCC ethernet:
* Multi ethernet interfaces can't work simultanously.
* Multi up/down Ethernet interfaces will halt these ports.
* UCC1 RGMII can't work when kernel boots from some hosts.

Add support for the msi-address-64 property of a PCI node. This property
specifies the PCI address of MSIIR (message signaled interrupt index
register).
In commit 3da34aae ("powerpc/fsl: Support unique MSI addresses per PCIe Root
Complex"), the msi_addr_hi/msi_addr_lo fields of struct fsl_msi were redefined
from an actual address to just an offset, but the fields were not renamed
accordingly. These fields are replace with a single field, msiir_offset,
to reflect the new meaning.

Normally logical and hard cpu ID are the same, however in same cases like
on the P3060 they may differ. Where the logical is 0..5, the hard id
goes 0,1,4..7. This can causes issues for places we utilize PIR to index
into array like in debug exception handlers for finding the exception
stack.
Move to setting up PIR with hard_smp_processor_id fixes the issue.
