First pass didn't boot, no kernel messages.  I'm going to go through
the ArchLinux ARM superpatch to see if there are any items not
directly pegged to the GoFlex that might be involved next, as well as
cutting my conf down to just what's needed for the GFN to cut down my
build times.  While I'm doing that, what do I NEED to configure for
proper DTS support?

CONFIG_ARCH_KIRKWOOD=y

CONFIG_ARCH_KIRKWOOD_DT=y
CONFIG_MACH_DREAMPLUG_DT=n
CONFIG_MACH_ICONNECT_DT=n
CONFIG_MACH_DLINK_KIRKWOOD_DT=n
CONFIG_MACH_IB62X0_DT=n
CONFIG_MACH_GOFLEX_DT=y

CONFIG_USE_OF=y
CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
CONFIG_CMDLINE=""
CONFIG_ATAGS_PROC=y

CONFIG_USE_OF=y
CONFIG_MTD_OF_PARTS=y
# CONFIG_MTD_PHYSMAP_OF is not set
CONFIG_OF=y
# CONFIG_OF_SELFTEST is not set
CONFIG_OF_FLATTREE=y
CONFIG_OF_EARLY_FLATTREE=y
CONFIG_OF_ADDRESS=y
CONFIG_OF_IRQ=y
CONFIG_OF_DEVICE=y
CONFIG_OF_I2C=m
CONFIG_OF_NET=y
CONFIG_OF_MDIO=y
CONFIG_OF_PCI=y
CONFIG_OF_PCI_IRQ=y
CONFIG_OF_MTD=y
# CONFIG_SERIAL_OF_PLATFORM is not set
CONFIG_OF_GPIO=y

Am I missing anything?
