I want to avoid setting the default environment in CONFIG_EXTRA_ENV_SETTINGS, therefore I've set CONFIG_DEFAULT_ENV_FILE="uEnv.txt" and created that text file but bitbake doesn't find it:

make[1]: *** No rule to make target 'uEnv.txt', needed by 'include/generated/defaultenv_autogenerated.h'. Stop.

This is what the tree and the files look like:

└── u-boot
    ├── files
    │   ├── ma1.cfg
    │   └── uEnv.txt
    └── u-boot-xlnx_%.bbappend

ma1.cfg:

CONFIG_USE_DEFAULT_ENV_FILE=y
CONFIG_DEFAULT_ENV_FILE="uEnv.txt"

u-boot-xlnx_%.bbappend:

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI_append_tmc = " \
    file://ma1.cfg \
    file://uEnv.txt \
    "

PACKAGE_BEFORE_PN += "${PN}-env"
RPROVIDES_${PN}-env += "u-boot-default-env"

I don't know where to put the uEnv.txt so it will be found. I already (blindly) tried to specify some different paths like CONFIG_DEFAULT_ENV_FILE="../uEnv.txt" but to no avail. I suspect that I need to put it somewhere in a do_configure_append() but I don't know where.

Searching for CONFIG_DEFAULT_ENV_FILE only yields results which state that it can be used to create the environment from a file[1], but unfortunately not how. Or, more precisely: How to use it with bitbake.

So I hope someone can help me here: What do I need to do so bitbake places the text file where make is going to find it?

You need to pass your uEnv.txt file to the build directory to be found by Make.

You can do this in your bbappend file like:

do_configure_append() {
    cp ${WORKDIR}/uEnv.txt ${S}
}
