We still have:

static const char * const kirkwood_dt_board_compat[] = {
	"globalscale,dreamplug",
	"globalscale,guruplug",
	"dlink,dns-320",
	"dlink,dns-325",
	"iom,iconnect",
	"raidsonic,ib-nas62x0",
	"qnap,ts219",
	"seagate,dockstar",
	"seagate,goflexnet",
	"buffalo,lsxl",
	"iom,ix2-200",
	"keymile,km_kirkwood",
	"lacie,cloudbox",
	"lacie,inetspace_v2",
	"lacie,netspace_lite_v2",
	"lacie,netspace_max_v2",
	"lacie,netspace_mini_v2",
	"lacie,netspace_v2",
	"mpl,cec4",
	"netgear,readynas-duo-v2",
	"plathome,openblocks-a6",
	"usi,topkick",
	"zyxel,nsa310",
	NULL
};

in that file. I think it does not make sense that we need to list
boards here that can be described fully by DT. When adding such a
board in the future, you will still need to adapt board-dt.c.

Should we remove the boards that you removed above here as well and
add

	"marvell,kirkwood-88f6192",
	"marvell,kirkwood-88f6281",
	"marvell,kirkwood-88f6282",
	"marvell,kirkwood-88f6283",
	"marvell,kirkwood-88f6702",
	"marvell,kirkwood-98DX4122",

or even just state "marvell,kirkwood"?
