- Subject: [PATCH 1/1] mtd: rawnand: add support for TH58NYG3S0HBAI4 NAND flash
- The Toshiba TH58NYG3S0HBAI4 is detected with 128 byte OOB while the flash
- has 256 bytes OOB. Since it is not an ONFI compliant NAND, the model name
- cannot be read from anywhere, add a static NAND ID entry to correct this.
- However, the NAND ID of this flash is inconsistent with the datasheet.
- The actual NAND ID is only 4 ID bytes, the last ID byte is missing.
- Datasheet available at (the ID table is on page 50):
- https://europe.kioxia.com/content/dam/kioxia/newidr/productinfo/datasheet/201910/DST_TH58NYG3S0HBAI4-TDE_EN_31565.pdf
- Datasheet NAND ID: {0x98, 0xa3, 0x91, 0x26, 0x76}
- Actual NAND ID: {0x98, 0xa3, 0x91, 0x26}
- It seems that this flash may be counterfeit, but another Toshiba flash
- also has the same problem. Maybe the driver has a bug, or some Toshiba
- nand flash is like this. Anyway, add a static NAND ID entry with only
- 4 ID bytes as a hack to make sure it works.
- Tested on Arcadyan AW1000 flashed with OpenWrt.
