I'm interested in extracting the u-boot config from an existing BSP. It does compile u-boot but I cannot find the config file and I definitely can invoke bitbake u-boot separately, i.e. there must be a .config file somewhere.

I did find the location of the bbapppends:

$ bitbake-layers show-appends | grep boot
/home/yocto/rzv_vlp_v3.0.0/build/../meta-renesas/recipes-rzg2l/recipes-bsp/u-boot/u-boot_2021.10.bbappend (skipped):

but searching in /home/yocto/rzv_vlp_v3.0.0/build/../meta-renesas/recipes-rzg2l/recipes-bsp/u-boot/ for "*config*" did not yield any results.

Background: I want to be able to compile u-boot separately with make, outside of Yocto and re-use the same configuration.
Can anyone give me any hints?
.config should be in build tree of u-boot, when you do bitbake u-boot,
please look into the builddir of u-boot under work folder
