Hello,
I am seeing this error in my build:

as the error message says it, 1 file in the root file system has to be installed by 1 package, and only one. The process of building an image with OE/bitbake is:
1. determine the list of all packages be installed. This is done by looking at all RDEPENDS for the 'image' you are building. 2. build all recipes that are needed by the image (and all their dependencies) 3. install all binary packages that were just built in #2 into a 'local root filesystem' 4. create an 'image' file (ext4, sd card, ...) from the rootfs in #3
#3 is basically just 'uncompressing' binary packages into a folder. So if 2 packages try to install the same file, it will fail and abort , like in your case. 1 file in the resulting rootfs belongs to 1 binary package.
In my build, I'm including meta-raspberrypi and meta-freescale-3rdparty in my manifest. These two meta layers include the following two files into the rootfs in various ways:
/lib/firmware/brcm/brcmfmac43430-sdio.txt /lib/firmware/brcm/brcmfmac43430-sdio.bin
For example, in the following files define a way of adding the firmware into the rootfs (there will be more ways they get into the build, saying as one is a .inc file):
meta-freescale-3rdparty/recipes-bsp/broadcom-nvram-config/broadcom-nvram-config.inc meta-raspberrypi/recipes-kernel/linux-firmware/linux-firmware_%.bbappend openembedded-core/meta/recipes-kernel/linux-firmware/linux-firmware_git.bb
My meta-layer is included after meta-freescale* and meta-raspberrypi, but before openembedded-core/meta in my BBLAYERS setup.
Order/priority won't matter here. if 1 file is to be found in 2 *different* packages, then installing these 2 packages into the same image will fail.
However, I want to provide a newer version of these two files in my build. So we created this recipe in our meta layer:
file: recipes-bsp/firmware-imx/firmware-imx_%.bbappend
SRCREV_linuxfirmware = "a61ac5cf8374edbfe692d12f805a1b194f7fead2" SRCREV_recalboxbuildroot = "f648e4b54eb5e4be593746d6cc51375b22a7efbd"

I am not familiar with the layers you are using, but I think that a bbappend for linux-firmware like they do in meta-rpi would be more appropriate. e.g. you would modify an existing package instead of making a new one.
It builds fine in a "normal" configuration. However, in a "test" build, where "dev-pkgs" is added to IMAGE_FEATURES, I get the error as above.
It probably means that linux-firmware is not included by default, and gets pulled in when you include dev-pkgs feature.
So how do I work around this issue? Am I doing the wrong thing by providing a bbappend to overlay these files?
Any advice appreciated.
Regards, Ryan.
