openwrt/package/boot/uboot-mediatek/patches/100-22-mtd-spi-nand-backport-from-upstream-kernel.patch
Daniel Golle d3a337a592 uboot-mediatek: additions from MTK SDK 
* updated SNAND/SNFI driver brings support for MT7981
 * add support for MediaTek NAND Memory bad Block Management (NMBM)
   (not used for any boards atm, but could be useful in future)
 * wire up NMBM support for MT7622, MT7629, MT7981 and MT7986
 * replace some local patches with updated version from SDK
 * bring some legacy precompiler symbols which haven't been converted
   into Kconfig symbols in U-Boot 2022.07, remove when bumbping to
   U-Boot 2022.10:
   100-28-include-configs-mt7986-h-from-SDK.patch
