Prefix internal functions and structs with modbus_.
Use unit_id consistently instead of node_addr.
Fix mbm_ remainder and rename to mbc_.
Rename struct modbus_frame to modbus_adu since
ADU is closer to what the structure represents.
Let the compiler/linker do the job and
remove ifdef around mbc_validate_fc03fp_response().

The test allow to test both server and client role
simultaneously. Currently only FRDM-K64F board supports
simultaneously server-client test.
To run the test on the board like reel board, where
only one UART interface is available, two device can be used.
One board has to be flashed with project that supports only
the server role and the other with the client role.

Add MODBUS RTU (over serial line) subsystem.
MODBUS RTU implementation supports booth server and
client roles. Some components of the implementation are based
on the uC/Modbus stack, which was published under Apache license,
(https://github.com/SiliconLabs/uC-Modbus

The nrfjprog utility is not capable of flashing a hex file which
affects the flash memories of both coprocessors of the nRF53 family of
SoCs.
However, the user is capable of creating such a hex file using the
HEX_FILES_TO_MERGE build system variable.
An example use case is to build a bluetooth controller application for
the network core, then use the zephyr.hex file in that build directory
as the HEX_FILES_TO_MERGE argument for a separate Bluetooth
application build targeting the app core.
Work around this by detecting the situation and doing the right thing
by splitting the hex file back up again, even if thats a bit awkward.
Splitting the hex into app and network core components allows them to
be flashed separately. This is the only way we can get the job done
with nrfjprog.
This is arguably nicer since there's just one 'west flash' invocation.
At least in the use case named above, you wouldn't need to rebuild the
controller application very often, so this is a simpler user workflow.

Kconfig option USB_HID_PROTOCOL_CODE does not allow to set

Add new API function to allow the application to set
Protocol Code per device. Deprecate USB_HID_PROTOCOL_CODE option.

Sync packet is always CARD to HOST and if it's combined with HOST
to CARD transfers in one single RM header packet, it's not allowed
due to RM implementation constraints. RM implementation allows same
type of data transfer direction in all the BD's populated under one

GCC10 introduced by default calls to out-of-line helpers to implement
atomic operations with the '-moutline-atomic' option. This is breaking
several tests because the embedded calls are trying to access the
zephyr_data region from userspace that is declared as MT_P_RW_U_NA,
triggering a memory fault.
Since there is currently no support for MT_P_RW_U_RO (and probably never
will be), disable the out-of-line helpers disabling the GCC option.

of a thread already being executed on another CPU.
All CPUs must ensure they're using the appropriate mapping after a

The size_t usage, especially in struct z_heap_bucket made the heap
header almost 2x bigger than it needs to be on 64-bit systems.
This prompted me to clean up our type usage to make the code more
efficient and easier to understand. From now on:
- chunkid_t is for absolute chunk position measured in chunk units
- chunksz_t is for chunk sizes measured in chunk units
- size_t is for buffer sizes measured in bytes

The end marker chunk was represented by the len field of struct z_heap.
It is now renamed to end_chunk to make it more obvious what it is.
And while at it...
Given that it is used in size_too_big() to cap the allocation size
already, we no longer need to test the bucket index against the
biggest index possible derived from end_chunk in alloc_chunk(). The
corresponding bucket_idx() call is relatively expensive on some
architectures so avoiding it (turning it into a CHECK() instead) is
a good thing.
