From: Daniel Golle Date: Sat, 20 Feb 2021 13:04:38 +0000 (+0000) Subject: uboot-mediatek: update to 2021.04-rc3 with MediaTek's patches X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9dfc2b3ca4dff28259576e21bc3ade910ff52a05;p=openwrt%2Fstaging%2Fneocturne.git uboot-mediatek: update to 2021.04-rc3 with MediaTek's patches MediaTek published their current U-Boot patchset on github: https://github.com/mtk-openwrt/u-boot/commits/mtksoc Import the platform patches from there (`00-mtk-*.patch`), arrange, them nicely, drop no longer needed local patches and rebase on top of U-Boot 2021.04-rc3. Tested and works well on Linksys E8450 (snand-1ddr) as well as Bananapi BPi-R64 (sdmmc-2ddr, emmc-2ddr).
