From: Daniel Golle Date: Mon, 11 Jul 2022 20:15:32 +0000 (+0100) Subject: uboot-ramips: add support for MT7621, merge into uboot-mediatek X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2f7fb57c12d7afe5be7747611bceec92a4c0c834;p=openwrt%2Fstaging%2Fnbd.git uboot-ramips: add support for MT7621, merge into uboot-mediatek * Merge uboot-ramips into uboot-mediatek. * Port support for the RAVPower RP WD009 to U-Boot 2022.07. * Add support for MT7621 and add builds for the reference boards. * Add builds for MT7620 and MT7628 reference boards. This should help to make development of U-Boot-level board support for all MediaTek targets much easier.
