Added support for multi-image DFU for nRF53 from internal flash which requires the region parameter of mcuboot_secondary_1 to be configurable. So that the mcuboot_secondary_1 partition is put into internal flash.

We need to make sure that the alignment for internal flash is the same as for mcuboot primary. That should be page aligned. Also we need to make this block different between external flash and internal flash configurations.

Do you know why the flash alignment in external flash is set to 4 by default then?
ref:

sdk-mcuboot/boot/zephyr/pm.yml

Line 24 in ccc7227

align: {start: 4}

This could potentially be a misconfiguration and it should be page aligned regardless.
Also should I look into potentially using

zephyr/dts.cmake:set_target_properties(devicetree_target PROPERTIES "DT_REG|/soc/flash-controller@4001e000|SIZE" "0x1000;")

For setting the alignment requirements so that it would be page aligned regardless of the device used.

Isn't this unproper for if CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY_1 is selected?

Why? You have both secondary in external flash and placing the secondary_1 after secondary makes sense.
If secondary is in internal flash it will be allocated to a different region which means this placement requirement will be ignored.

The first sentence was obvious. The second one sentence describes something i could anticipate, but didn't know for sure.

[nrf noup] Restore default RTC user channel count

The default value of CONFIG_NRF_RTC_TIMER_USER_CHAN_COUNT
for nRF52 SOCs has been changed from 0 to 3, but it makes
MCUBoot get stuck on erasing flash pages when swapping two
images. Restore the previous value until the RTC issue is

[nrf noup] treewide: add NCS partition manager support
71fe2df 
Partition Manager is an nRF Connect SDK component which uses yaml
files to resolve flash partition placement with a holistic view of the
device.

This component's MCUboot portions began life as upstream mcuboot
PR#430. This added support for being built as a sub image from the
downstream Nordic patch set for a zephyr multi image build
system (mcuboot 430 was combined with effor submitted to upstream
zephyr as PR#13672, which was ultimately reworked after being rejected
for mainline at the ELCE 2019 conference in Lyon).

It has since evolved over time. This is the version that will go into
NCS v1.3. It features:

- page size aligned partitions for all partitions used by mcuboot.
- image swaps without scratch partitions

Add support for configurations where there exists two primary slots
but only one secondary slot, which is shared. These two primary slots
are the regular application and B1. B1 can be either S0 or S1
depending on the state of the device.

Decide where an upgrade should be stored by looking at the vector
table.

Provide update candidates for both s0 and s1. These candidates must be
signed with mcuboot after being signed by b0.

Additional notes:

- we make update.hex without trailer data

  This is needed for serial recovery to work using hex files.
  Prior to this the update.hex got TLV data at the end of the
  partition, which caused many blank pages to be included,
  which made it hard to use in a serial recovery scheme.

  Instead, make update.hex without TLV data at the end,
  and provide a new file test_update.hex which contains
  the TLV data, and can be directly flashed to test the
  upgrade procedure.

- we use a function for signing the application as future-proofing
  for when other components must be signed as well

- this includes an update to single image applications that enables
  support for partition manager; when single image DFU is used, a
  scratch partition is not needed.

- In NCS, image 1 primary slot is the upgrade bank for mcuboot (IE S0 or
  S1 depending on the active slot). It is not required that this slot
  contains any valid data.

- The nRF boards all have a single flash page size, and partition
  manager deals with the size of the update partitions and so on, so we
  must skip a boot_slots_compatible() check to avoid getting an error.

- There is no need to verify the target when using partition manager.

- We lock mcuboot using fprotect before jumping, to enable the secure
  boot property of the system.

- Call fw_info_ext_api_provide() before booting if EXT_API_PROVIDE
  EXT_API is enabled. This is relevant only when the immutable
  bootloader has booted mcuboot.

[nrf noup] boot: nrf53-specific customizations
2bbd3b1 
- Add network core bootloader implementation

  Enables network core updates of nrf53 using MCUBoot by identifying
  images through their start addresses. Also implements the control and
  transfer using the PCD module.

- Add support for multi image DFU using partition manager.

- Add check for netcore addr if NSIB is enabled so netcore updates works

- boot: zephyr: move thingy53_nrf5340_cpuapp.conf downstream

  Moved the board configuration for Thingy:53 Application Core to the
  nRF Connect SDK MCUboot downstream repository. The configuration file
  contains references to the Kconfig modules that are only available in
  the nRF Connect SDK. The current configuration is set up to work in the
  nRF Connect SDK environment and cannot be used upstream.

- pm: enable ram flash partition using common flag

  This patch makes mcuboot_primary_1 ram-flash partition
  selectable using CONFIG_NRF53_MCUBOOT_PRIMARY_1_RAM_FLASH
  property. This is needed since CONFIG_NRF53_MULTI_IMAGE_UPDATE
  become not only configuration which requires that partition.

- MCUBoot configures USB CDC by its own. There is no need for
  BOARD_SERIAL_BACKEND_CDC_ACM option to configure anything which is
  later overwritten anyway.

[nrf noup] do_boot: clean peripherals state before boot
4c8e041 
Do some cleanup of nRF peripherals. This is necessary since Zephyr
doesn't have any driver deinitialization functionality, and we'd like
to leave peripherals in a more predictable state before booting the
Zephyr image. This should be re-worked when the zephyr driver model
allows us to deinitialize devices cleanly before jumping to the
chain-loaded image.

[nrf noup] loader: Fix reading reset addr to support ext flash
9403865 
When mcuboot_secondary is on external flash, the image header cannot
dircetly be accessed via secondary_fa->fa_off. Instead the provided
function boot_img_hdr() is used now.
Additionally a similar issue is present when trying to read the address
of the reset handler. For this flash_area_read() is used now.

With this patch is possible to have the update partiton
mcuboot_secondary on external flash and update a updatable
bootloader (mcuboot) in s0 and/or s1.

This adds support for using both NSIB and the multi-image configuration

support through NSIB was using the `UPDATEABLE_IMAGE_NUMBER`
configuration to update the updateable bootloader.

In this commit we change from using `FLASH_AREA_IMAGE_PRIMARY` to get
the flash area ID to using the bootloader state where we set the flash
area ID of the free updatable bootloader slot if the image is intended
for this slot.
