5d14cddaa8 Bluetooth: ISO: Fixes ISO central disconnect and cleanup issues
When an ISO channel is disconnect on the central, it is
not deallocated, but merely disconnected. This is because,
as per the HCI spec, the CIS handle lives on in the CIG.

Instead of unref'ing the bt_conn to 0, we simply put the
channel and connection in the disconnected state.

This also fixes a few missing returns for
terminating a CIG.

93bfe7a2c9 Bluetooth: ISO: Update BIS index to start from 0x01
The HCI spec defines the BIS index range as starting from
index 0x01. We had previously implemented it such that it
starts from 0x00, and then simply adding 1 to the index
when sending over HCI. However, this may cause issue with
other HCI, or other SIG defined specification, commands
and events, and thus it is probably simpler if we just
use the HCI defined range.

This commit disallows BIT(0) (representing the BIS
index 0x00) to be set, and removes the addition
of 1 when sending over HCI.

ec2b9d42af pcie: msi: pci_msi_enable() to take IRQ as parameter
This changes pci_msi_enable() to take IRQ number as a function
parameter. The old behavior relies on putting the IRQ number
into the interrupt line register in the PCI config space
during IRQ allocation, and reading it back when enabling IRQ.
However, the interrupt line register is only required to be
read-/writable when legacy interrupt is supported on the device.
Otherwise it has undefined behavior. On ACRN, they don't even
care about this register and always wires it to 0x00.
So this commit changes the behavior in pci_msi_enable() to not
require reading back the interrupt line register and instead
takes the IRQ number via function parameter.

Fixes #36765

a28830b811 linker: align __itcm_load_start / __dtcm_data_load_start linker symbols
Cleanup and preparation commit for linker script generator.

Zephyr linker scripts provides start and end symbols for each section,
and sometimes even size and LMA start symbols.

Generally, start and end symbols uses the following pattern, as:
Section name:             foo
Section start symbol:     __foo_start
Section end symbol:       __foo_end

However, this pattern is not followed consistently.
To allow for linker script generation and ensure consistent naming of
symbols then the following pattern is introduced consistently to allow
for cleaner linker script generation.
Section name:             foo
Section start symbol:     __foo_start
Section end symbol:       __foo_end
Section size symbol:      __foo_size
Section LMA start symbol: __foo_load_start

This commit aligns the symbols for __itcm_load_start and
__dtcm_data_load_start to other symbols and in such a way they follow
consistent pattern which allows for linker script and scatter file
generation.

The symbols are named according to the section name they describe.
Section names are itcm and dtcm.

c6aded2dcb linker: align _image_rodata and _image_rom start/end/size linker symbols

Zephyr linker scripts provides start and end symbols for each larger

kobject-rom.ld and snippets-rodata.ld.

This commit align those names and prepares for generation of groups in
linker scripts.

The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end   -> __rom_region_end

The rodata will also use the group symbol notation as:

0c2dabb4b9 ipc: rpmsg_multi_instance: Rework instance tracking
This patch is the first step to make the rpmsg_multi_instance usable in
a multi-core scenario.

The current driver is using a local driver variable (instance) to track
the number of allocated instances. This counter is practically used to
allocate to the instance the correct portion of the shared memory.

This is fundamentally wrong because this is assuming that it does exist
only one single shared memory region to split amongs all the allocated
instances.  When the platform has more than one core this is obviously
not the case since each couple of cores are communicating using a
different memory region.

To solve this issue we introduce a new struct rpmsg_mi_ctx_shm_cfg that
is doing two things: (1) it's carrying the information about the shared
memory and (2) it's carrying an internal variable used to track the
instances allocated in that region. The same struct should be used every
time a new instance is allocated in the same shared memory region.

We also fix a problem with the current code where there is a race
between threads when accessing the instance variable, so this patch is
adding a serializing mutex.

For the instance configuration the rpmsg_multi_instance code is
currently using a set of configuration info coming from two different

This is not only confusing but it's preventing to configure the

want to configure the instance using DT).
