In Infineon XMC4XXX SoCs, gpio interrupts are triggered via an
Event Request Unit (ERU) module. A subset of the gpios are
connected to the ERU. The ERU monitors edge triggers and creates
a SR.
This driver configures the ERU for a target port/pin combination
for rising/falling edge events. Note that the ERU module does
not generate SR based on the gpio level. Internally the ERU
tracks the *status* of an event. The status is set on a positive
edge and unset on a negative edge (or vice-versa depending on
the configuration). The value of the status is used to implement
a level triggered interrupt; The ISR checks the status flag and
calls the callback function if the status is set.
The ERU configurations for supported port/pin combinations are
stored in a devicetree file dts/arm/infineon/xmc4xxx_x_x-intc.dtsi.
The configurations are stored in the opaque array
uint16 port_line_mapping[].

Currently, memory from __rodata_region_end to __kernel_ram_start (or

There is the possibility that when reconfiguring the static regions,
some data that must be accessed is temporarily not accesible due to the
change on the MPU regions configuration. Workaround by disabling MPU
when doing the reconfiguration, same as with dynamic regions, until BR
can be enabled.

Change Summary:
Update Base addr to set direction to use Aligned IP base address instead
of Port Base Address. Port Base Address + offset to direction register
will set incorrect value for Port B,C & D. For ex: In cases when more than
1 port is configured on the same IP, the DTS node for port B will start
at offset 0xC. Calculating the port using Port Base will yield offset of
PORTB DIR register which is at offset 0x10 from Aligned Base, and as a
result will result in setting DIR register of PORTC instead.

Move the existing ivshmem test to a folder that explicitly identifies
its target: ivshmem-plain. The existing test is not compatible with
ivshmem-doorbell.
ivshmem-doorbell has additional requirements compared to -plain
(ivshmem-server, notification handling), so it is reasonable that
another test is required for it. This commits prepares the way for the new

For architectures that rely on a PCIe controller (for example, ARM64),
scanning the PCI space will only succeed after the controller has
initialized. Therefore, in the presence of PCIe controller, the PCIe
initialization is bumped to the next system init level.
In the past, drivers like ivshmem would do a late scan of the PCI space
in case the early scan failed; however, the cited commit removed this
feature and ivshmem fails for ARM64. This commit fix this by making the
early scan succeed.

Starting with commit b9b43a0eb772a464bba13833d11e3a31fbf4e09e, printk()
messages are handled by the logging subsystem. This can cause trouble
in watchdog related samples if the deferred logging mode is used (and
currently it is by default), because those samples are ended by a reset
and some messages may not get a chance to be outputted.
Since the same problem concerns also the ordinary logging messages that
may be produced during execution of the samples, this commit fixes it
by switching to the immediate logging mode, not by just disabling the
LOG_PRINTK option.
