+Subject: mtd: nand: realtek-ecc: relax OOB size check to minimum
+
+The ECC engine strictly validates that flash OOB size equals exactly
+64 bytes. However, some NAND chips have a larger physical OOB while
+vendor firmware only uses the first 64 bytes for the ECC layout. For
+example the Macronix MX35LF1G24AD found in the Netlink HG323DAC has
+128 byte physical OOB but vendor firmware only uses the first 64
+bytes (24 bytes free + 40 bytes BCH6 parity), leaving bytes 64-127
+unused.
+
+Since the engine only operates on the first 64 bytes of OOB
+regardless of the physical size, change the check from exact match
+to minimum size. Flash with OOB >= 64 bytes works correctly with
+the engine's 64-byte layout.
