From 2ea8610e4fcaa13208432b0242ca82e18e1f3da6 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Sat, 2 Mar 2024 21:07:37 +0800 Subject: [PATCH] uboot-mediatek: add Redmi AX6S as UBI loader Add support for Xiaomi Redmi AX6S to be used as a second-stage UBI loader. The defconfig/env is minimal: Boot fit from UBI. If that failed, load and boot initramfs image from TFTP.
