In an effort to reduce the footprint of the LwM2M client, let's

The slist attr_list doesn't scale well when added to the LwM2M object,
object instance and resource instance structures. The goal of a
robust LwM2M client is to let the user create MANY object instances
and these will have many resource instances each. The amount of SRAM
taken up by the attr_lists will only increase over time, regardless
of the actual # of write attribute structures reserved via the
LWM2M_NUM_ATTR config setting.
Instead, let's remove the slist from these structures and add a
reference pointer to the lwm2m_attr structure. We can use this
reference to create the one to many relationship between the objects,
object instances and resource instances for a much smaller amount of
code and SRAM resources.
The sacrifice for these savings will be a larger # of iterations when
looking up assigned write attributes and matching them to their
references. However, due to the # of write attributes current being
handled, the # of iterations during this process is very manageable.
Example flash and SRAM savings when building for nrf52_blenano2:
Before patch:
Memory region Used Size Region Size %age Used
FLASH: 139532 B 512 KB 26.61%
SRAM: 36576 B 64 KB 55.81%

for the typical configuration of LwM2M client in Zephyr.

There are valid use cases where the model layer must know the true
destination address. So far only the fact that it was one of the
addresses that the model subscribes to (its element's unicast
included) has been knowable.
Solve the issue by moving the destination address from the internal
net_rx context to the public bt_mesh_msg_ctx struct.

MPU devices that enforce power-of-two alignment now
specify the size of the buffer used for the newlib heap.
This buffer will be properly aligned and a pointer
exposed in a kernel header, such that it can be added
to a user thread's memory domain configuration if
necessary.
MPU devices that don't have these restrictions allocate
the heap as normal.
In all cases, if an MPU/MMU region needs to be programmed,
the z_newlib_get_heap_bounds() API will return the necessary
information.
Given how precious MPU regions are, no automatic programming
of the MPU is done; applications will need to do this as
needed in their memory domain configurations.
On x86, the x86 MMU-specific code has been moved to arch/x86
using the new z_newlib_get_heap_bounds() API.

'cell_string' yaml attribute has been introduced in order to
help enforcement of specific string during defines generation.
This adds complexity in understanding script behavior as a black
box and create additional dependency which is not strictly required.
For node specific generation functions (pinctrl and interrupts),
this could be replaced directly by an hardcoded version
(as everyone used the same 'cell_string' anyway).
For extract_cells functions, string could be replaced by extracted
property name. As a consequence, we're now able to generate defines
for properties refering to these controllers via phandle.
For instance, in following node
spbtle-rf@0 {
compatible = "st,spbtle-rf";
reg = <0>;
reset-gpios = <&gpioa 8 0>;
};
We'll be able to generate:
#define ST_STM32_SPI_...LE_RF_0_RESET_GPIOS_CONTROLLER "GPIOA"
#define ST_STM32_SPI_...PBTLE_RF_0_RESET_GPIOS_FLAGS_0 0
#define ST_STM32_SPI_..._SPBTLE_RF_0_RESET_GPIOS_PIN_0 8
Only impact for this whole change is for NXP clocks which were the
only ones using 'cell_string' attribute with a value different than
the default one.
