[U-Boot] [PATCH v3 5/5] ls2080ardb: Convert to distro boot

[Alexander Graf]

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.

Signed-off-by: Alexander Graf <agraf at suse.de>

v1 -> v2:

  - Boot NOR flash before distro boot

v2 -> v3:

  - Actually run distro boot (s/&&/||/ after bootm)
