I checked with Patrice the other boards and most of the cases the modified spl
binay
(u-boot-spl.bin/ u-boot-spl.ais / u-boot-spl.img / u-boot-spl.pbl /
u-boot-spl.gph)
are generated in spl directory.
So I done the same for u-boot-spl.stm32.
The only case where it is populated in u-boot directory it is when it is
concatenated with u-boot image
(so the generated files depends on u-boot.bin) , but is not the case for us.
Perhaps I miss so other cases ?
Moreover I am working with YOCTO and using a sub-directory is not issue with
latest version
and with patch in poky/meta/recipes-bsp/u-boot/u-boot.inc

u-boot.inc: Add sub-dir support for SPL_BINARY
Add support for the SPL_BINARY variable to handle sub directories. In
some cases the SPL binary that needs to be deployed is only built to the
spl/ directory in U-Boot. So that a sub directory can be specified in
the SPL_BINARY variable, handle the case so that the deploy code uses
the basename of the path specified in SPL_BINARY.

So, I don't understood the blocking point, and other platform do the same (the
reason of the patch).
Even I agree that copy the generated u-boot-spl.stm32 in u-boot build directory
could be easier (for BUILDROOT ?),
I want keep the file spl/u-boot-spl.stm32 to avoid to break the current
upstream effort
of YOCTO BSP support for STM32MP157 board (which expect spl file in spl
directory).
I you are agree with the next proposal, I will ack you patch v2
=> a modified patch to just copy with $(call if_changed,copy)

Subject: [PATCHv2] arm: stm32mp1: deploy spl in root folder
Deploy u-boot-spl.stm32 binary in u-boot root folder like the rest of
the boards. This makes it more streamlined when building in Yocto,
Buildroot etc..
