No. I did not. My FDT was simplified from the stock MPC8272ADS:
=> fdt list
/ {
        model = "pq2fads";
        compatible = "fsl,pq2fads";
        #address-cells = <0x00000001>;
        #size-cells = <0x00000001>;
        cpus {
        };
        memory {
        };
        soc@f0000000 {
        };
        chosen {
        };
};
I am searching how I could add the mtd branch between the "soc" and
the "chosen".

Hello,
My uboot can read my flash chip, finding the uImage and the initramfs,
and booting the kernel fine. However, I'd like the Linux kernel to
read my flash chip so that it can update files in it.

Have you described your flash chip in the device tree?

However, the kernel does not detect any flash chip (nor there's any
indication that a CFI probe is being performed).

The stock device tree for mpc8272ads only specifies it as a JEDEC
flash, not CFI.
