[][Critical][kernel][common][spinand][Add CASN support for SPI-NAND]

[Description]
Add CASN page support for SPI-NAND. CASN page has a full description
for SPI-NAND. Software driver can utililize it to address the whole
NAND chip. Also, it can handle ECC information as well. CASN page is
designed to solve the following problems:
1. Increasing size of SPI-NAND flash tables, which exist in
various drivers/mtd/nand/spi/*.c files.
2. Efforts on adding new SPI-NAND's flash tables.
3. Extract correct flash on-die ECC's bitflip numbers if it
supports advanced ECC status registers. The on-die ECC engine design
varies from vendor to vendor. CASN can transform them into unified
format.
4. A single Linux Kernel image can deal with most of SPI-NAND devices.

Brief introduction for using MediaTek released OpenWrt SDK

1. Build system setup

2. Clone vanilla OpenWrt

Currently two release branches are supported:

  1. 21.02 This is the current in-use branch

    git clone -b openwrt-21.02 https://git.openwrt.org/openwrt/openwrt.git

  2. master (will be 24.0x branch later) The next version in development

    git clone https://git.openwrt.org/openwrt/openwrt.git

3. Add MediaTek OpenWrt feed

cd openwrt
echo "src-git mtk_openwrt_feed https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds" >> feeds.conf.default
./scripts/feeds update -a
./scripts/feeds install -a

4. Apply MediaTek OpenWrt files and patches

  1. 21.02 branch

    cp -af ./feeds/mtk_openwrt_feed/21.02/files/* .
cp -af ./feeds/mtk_openwrt_feed/tools .
for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-feeds -name "*.patch" | sort); do patch -f -p1 -i ${file}; done

  2. master branch

    cp -af ./feeds/mtk_openwrt_feed/master/files/* .
for file in $(find ./feeds/mtk_openwrt_feed/master/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done

5. Configuration

make menuconfig

  1. 21.02 branch

    Target System -> MediaTek Ralink ARM
Subtarget -> MT7981 / MT7986 / MT7988
Target Profile -> select as needed

  2. master branch

    Target System -> MediaTek Ralink ARM
Subtarget -> Filogic 8x0 (MT798x)
Target Profile -> select as needed

6. Build

make V=s -j$(nproc)
