By default U-Boot reserve overlay sizee with 4KB padding, sometime it is
not enought and it is normal.
The caller NEED to reserved enought memory before to apply overlay
by usisng the <extrasize> parameter.
fdt resize [<extrasize>]
- Resize fdt to size + padding to 4k addr + some optional <extrasize> if needed
A correct value cannot be proposed (it is depending of the overlay size)
but at least you must reserved the size of the loaded overlay dtbo file
=> ${filesize} (this variable automatically updated after a load command)

Summary
meta-st-stm32mp BSP layer is a layer containing the STMicroelectronics bsp metadata for current versions of stm32mp.
This layer relies on OpenEmbedded/Yocto build system that is provided through Bitbake and OpenEmbedded-Core layers or Poky layer all part of the Yocto Project
The Yocto Project has extensive documentation about OE including a reference manual which can be found at:
For information about OpenEmbedded, see the OpenEmbedded website:
This layer depends on:
[OECORE]
URI: https://github.com/openembedded/openembedded-core.git
layers: meta
branch: same dedicated branch as meta-st-stm32mp
revision: HEAD
[BITBAKE]
URI: https://github.com/openembedded/bitbake.git
branch: branch associated to oecore branch
revision: HEAD
or
[OECORE]
URI: git://git.yoctoproject.org/poky
layers: meta
branch: same dedicated branch as meta-st-stm32mp
revision: HEAD
[META-OPENEMBEDDED]
URI: git://github.com/openembedded/meta-openembedded.git
layers: meta-python meta-oe
branch: same dedicated branch as meta-st-stm32mp
revision: HEAD
The dependency (meta-python) are due to the usage of OPTEE which require to use some python packages.
EULA
Some SoC depends on firmware and/or packages that are covered by STMicroelectronics EULA. To have the right to use those binaries in your images you need to read and accept the EULA available as:
conf/eula/$MACHINE, e.g. conf/eula/stm32mp1
In order to accept it, you should add, in your local.conf file:
ACCEPT_EULA_$MACHINE = "1", e.g.: ACCEPT_EULA_stm32mp1 = "1"
If you do not accept the EULA the generated image will be missing some components and features.
