From: Chukun Pan Date: Mon, 18 Sep 2023 13:28:01 +0000 (+0800) Subject: uboot-mediatek: sync spi-nand driver with SDK X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eb273ef640674de1b5c1dba8a35bf7be044016f8;p=openwrt%2Fstaging%2Fansuel.git uboot-mediatek: sync spi-nand driver with SDK When adding new router support, I found that uboot could not recognize flash: "unknown raw ID xxx". Sync SPI-NAND driver for mediatek to fixes this: * Add support for Winbond W25N01KV 1Gbit chip. * Add support for Etron SPI-NAND chip.
