From: Simon Glass Date: Mon, 25 Apr 2022 05:31:10 +0000 (-0600) Subject: bootstd: Add a bootdev command X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=5d053cca387dc92040569278b76d65391c91c249;p=u-boot.git bootstd: Add a bootdev command Add a 'bootdev' command to handle listing and selection of bootdevs. Disable standard boot for a few boards which otherwise run out of space.
