At chip startup, jtag pins are configured by default to enable
debug.
This configuration adds consumption and when using PM profile,
we can save ~40uA by resetting this configuration and setting pins
to analog mode.

The STM32G0 soc has 2 CAN controllers. The 2nd on was not working
with zephyr yet as both controllers shares the same IRQ. Recently, the
shared irq system was integrated on now, both can controllers can work
on this chip. Shared interrupts must be enabled only if both can
controllers are enabled.

Supporting Stop1 mode while BLE RF is enabled requires some specific

scm (Secure clock manager) is in charge of switching clock depending

STM32WBA controller uses a PKA driver to perform cyphering operations
on keys. Since PKA hardware block requires RNG clock to be enabled, a
synchronization with zephyr RNG driver is needed.
Use RNG enable status to check if RNG could be switched off or needs to
be switched on.
Similarly in entropy driver, don't cut RNG clock if PKA is enabled.

Add soc power management for the STM32F4x chips.
One low power state is added supported by all chips from the family -
the Stop mode with voltage regulator in low-power mode.
The Stop mode for STM32F chips has to work with the IDLE timer -
CORTEX_M_SYSTICK_IDLE_TIMER, because PLL and HSI are disabled in the
Stop mode (Systick is not clocked). The only possible wakeup source is
RTC, which works as a IDLE timer for the Systick.
The exit latency may need to be adjusted per system, depending on the
system tick frequency and other variables.

Force STM32_ENABLE_DEBUG_SLEEP_STOP option when running tests.
This option enables Debug in Sleep/stop states and disables it when
disabled (default state).
When disabled, it may be impossible to flash the device with runner
such as openocd. It's generally working using cubeprogrammer, but it might
fail as well with fault configuration.
Instead of fixing each test or breaking CI each time a new test is created
with CONFIG_PM=y, force this option to be enabled when ZTEST=y (as it was
already the case when DEBUG=y).

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.
