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"?
