| mtd: nand: realtek-ecc: support OOB size override from device tree | |
| Some NAND chips have a physical OOB size larger than what vendor | |
| firmware actually uses for its ECC layout. For example the Macronix | |
| MX35LF1G24AD found in Netlink HG323DAC has 128 byte OOB but vendor | |
| firmware only uses the first 64 bytes for the BCH6 ECC layout. The | |
| Realtek ECC engine strictly validates flash geometry against its | |
| supported configuration which causes probe failure on these chips. | |
| Add support for a "realtek,ecc-oob-size" device tree property on the |
