You asked to change your rootfs (initrd, I presume)
fsl-image-minimal-p1022ds.ext2.gz.u-boot, and setting SERIAL_CONSOLE
adjusts the parameters for inittab.

If you want to change u-boot as well (but this is outside
fsl-image-minimal-*) and you do not want to compile it outside Yocto,
you have to put the patch you already have in your bsp directory and
adjust your u-boot receipe.
