I am trying to build a custom Yocto Scarthgap image for a custom STM32MP153CAA3 board.
I have followed the guide at https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine but have several issues.
I have created a configuration in CubeMX 6.15.0 and exported the DTB into my project.
When I try and build I get an error in u-boot
ERROR (phandle_references): /soc/rcc@50000000: Reference to non-existent node or label "clk_hse"
(along with references to other clock nodes)
I do a `devtool modify u-boot-stm32mp` to get at the source code and follow through the DTB
The includes from the u-boot DTB file from CubeMX are:
#include "stm32mp153.dtsi"
#include "stm32mp15xa.dtsi"
#include "stm32mp15xxaa-pinctrl.dtsi"
#include "stm32mp15-m4-srm.dtsi"
#include "stm32mp15-scmi.dtsi"
stm32mp153.dtsi includes stm32mp151.dtsi which references the clocks, which is great.
However the last include, stm32mp15-scmi.dtsi then goes and deletes them all!
/delete-node/ &clk_hse;
/delete-node/ &clk_hsi;
/delete-node/ &clk_lse;
/delete-node/ &clk_lsi;
/delete-node/ &clk_csi;
Is this deliberate or am I missing something here?
Then, if I add the clock values back in (also needed for the Kernel DTBs for the same reason) I can get it to compile, but when I then try and flash the emmc image, it fails

Again, what am I missing?
