Cortex-R52 supports both Arm and Thumb-2 mode, but Zephyr's ASM
code for Armv-8 Aarch32 is written for Arm mode only. This Soc
has a general purpose register that can set the core TEINIT signal
to change the mode exceptions are taken before booting up the core.
The debugger startup scripts or firmware booting up the core may
configure this bit to Thumb mode, as is the case of the NXP S32 debug
probe startup scripts for S32ZE.
Due to above reason, clear SCTLR.TE bit at reset so that TEINIT value
is ignored and exceptions are always taken into Arm mode, compatible
with current Zephyr ASM code. At least until taking execeptions in Thumb
mode is supported in Zephyr.

On S32K344, the offset in memory map between each channel
is 0x4000 for most channels, but there is specific case is
between channel 11 and 12 which is 0x1D4000 instead. As a
consequence, 32 channels are divided to two parts: one
starts from channel 0 -> 11. The other is from channel 128
to 145. The channel gap is from 12 -> 127.
For user and data structures in shim driver, the channel's
value comes from 0 --> 31. Above constraint will be counted
when interact with the mcux sdk
Beside that, the DMAMUX register in this platform is very
specific, not in identical with DMAMUX channel, so shim
driver is updated to cover this case

This is the final step in making the `zephyr,memory-attr` property
actually useful.
The problem with the current implementation is that `zephyr,memory-attr`
is an enum type, this is making very difficult to use that to actually
describe the memory capabilities. The solution proposed in this PR is to
use the `zephyr,memory-attr` property as an OR-ed bitmask of memory
attributes.
With the change proposed in this PR it is possible in the DeviceTree to
mark the memory regions with a bitmask of attributes by using the
`zephyr,memory-attr` property. This property and the related memory
region can then be retrieved at run-time by leveraging a provided helper
library or the usual DT helpers.
The set of general attributes that can be specified in the property are
defined and explained in
`include/zephyr/dt-bindings/memory-attr/memory-attr.h` (the list can be
extended when needed).
For example, to mark a memory region in the DeviceTree as volatile,
non-cacheable, out-of-order:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_VOLATILE |
DT_MEM_NON_CACHEABLE |
DT_MEM_OOO )>;
};
The `zephyr,memory-attr` property can also be used to set
architecture-specific custom attributes that can be interpreted at run
time. This is leveraged, among other things, to create MPU regions out
of DeviceTree defined memory regions on ARM, for example:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-region = "NOCACHE_REGION";
zephyr,memory-attr = <( DT_ARM_MPU(ATTR_MPU_RAM_NOCACHE) )>;
};
See `include/zephyr/dt-bindings/memory-attr/memory-attr-mpu.h` to see
how an architecture can define its own special memory attributes (in
this case ARM MPU).
The property can also be used to set custom software-specific
attributes. For example we can think of marking a memory region as
available to be used for memory allocation (not yet implemented):
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_NON_CACHEABLE |
DT_MEM_SW_ALLOCATABLE )>;
};
Or maybe we can leverage the property to specify some alignment
requirements for the region:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_CACHEABLE |
DT_MEM_SW_ALIGN(32) )>;
};
The conventional and recommended way to deal and manage with memory
regions marked with attributes is by using the provided `mem-attr`
helper library by enabling `CONFIG_MEM_ATTR` (or by using the usual DT
helpers).
When this option is enabled the list of memory regions and their
attributes are compiled in a user-accessible array and a set of
functions is made available that can be used to query, probe and act on
regions and attributes, see `include/zephyr/mem_mgmt/mem_attr.h`
Note that the `zephyr,memory-attr` property is only a descriptive
property of the capabilities of the associated memory region, but it
does not result in any actual setting for the memory to be set. The
user, code or subsystem willing to use this information to do some work
(for example creating an MPU region out of the property) must use either
the provided `mem-attr` library or the usual DeviceTree helpers to
perform the required work / setting.

So far the init priories were:
enetc_psi0=60 < enetc_vsin=61 < emdio=70 < ethernet-phy=80
because the Ethernet PSI driver was doing global initialization for the
whole NETC complex, including enabling MDIO function (due to the way
the HAL works).
Change to use the default init priorities:
mdio=60 < phy=70 < eth=enetc_psi0=80 < enetc_vsin=81
by executing at an early stage the NETC global initialization. This also
allows to match the DT hierarchy representation of NETC with the
effective priorities assigned.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.
