Most new systems in U-Boot these days make use of the generic "distro" framework which allows a user to have U-Boot scan for a bootable OS on all available media types.
This patch extends the LS2080ARDB board to use that framework if the hard coded NOR flash location does not contain a bootable image.

v1 -> v2:
- Boot NOR flash before distro boot
v2 -> v3:
- Actually run distro boot (s/&&/||/ after bootm)
v3 -> v4:
- Add CONFIG_CMD_FS_GENERIC to defconfig
v4 -> v5:
- Add qspi board - Don't overwrite ethact
v5 -> v6:
- Move distro conversion to end of queue - use CONFIG_DISTRO_DEFAULTS
v6 -> v7:
- Add USB boot support --- Kconfig | 1 + include/configs/ls2080ardb.h | 26 +++++++++++++++++++++++++- 2 files changed, 26 insertions(+), 1 deletion(-)
