Perhaps take a look at mvebu (Linksys WRT1200AC/ WRT1900AC/ WRT1900ACS/
WRT3200ACM/ WRT32x), ipq40xx (Linksys EA6350v3/ EA8300, ZyXEL NBG6617)
or ipq806x (ZyXEL NBG6817) for inspiration (append-rootblock[0]).

Taking the bootloader cmdline as-is is probably not going to work, as
quite a lot of ath79 devices depend on a different kernel/ rootfs
split for the flash partitioning.
