Subject: distro_bootcmd: add NVME support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9493e39cd4efef1dcd8420235685b90a0190f752;p=project%2Fbcm63xx%2Fu-boot.git

distro_bootcmd: add NVME support

Some boards support NVME drives. We should be able to use them as boot
devices.

NVME access requires running 'nvme scan'.
