I can't reproduce the problem here, doing :
$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j8 zImage
$ cat arch/arm/boot/<random>.dtb >> arch/arm/boot/zImage
$ ls -l arch/arm/boot/zImage
-rwxrwxr-x 1 max max 2577673 oct. 3 13:36 arch/arm/boot/zImage
$ md5sum arch/arm/boot/zImage
d88b9ddc04847e06b34f80841a973ce5 arch/arm/boot/zImage
$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j8 uImage
$ ls -l arch/arm/boot/zImage
-rwxrwxr-x 1 max max 2577673 oct. 3 13:36 arch/arm/boot/zImage
$ ls -l arch/arm/boot/uImage
-rw-rw-r-- 1 max max 2577737 oct. 3 13:37 arch/arm/boot/uImage
$ md5sum arch/arm/boot/zImage
d88b9ddc04847e06b34f80841a973ce5 arch/arm/boot/zImage
So it definitely looks to me like the zImage is left untouched.
What are you doing to see that behaviour? What is your configuration file? What
kernel version are you using?
(In reply to comment #0)

I don't get by looking at that code why the zImage should be overwritten?
