This patchset is for the new series of Micron SPI NAND devices, and the following links are their datasheets.
While boot NXP ls2088 device with mainline kernel the following nand
warning
noticed. How critical this warning ?
Are you sure this is the right thread? Shivamurthy added SPI-NAND support, you are talking about a raw NAND device.
[ 1.357722] nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x48 [ 1.364085] nand: Micron MT29F16G08ABACAWP [ 1.368181] nand: 2048 MiB, SLC, erase size: 512 KiB, page size: 4096, OOB size: 224 [ 1.375932] nand: WARNING: 530000000.flash: the ECC used on your system is too weak compared to the one required by the NAND chip
If you are talking about this one, it is pretty self explanatory: the NAND chip requires a minimum correction which is not achieved here. Either because the ECC engine cannot reach the requested amount (you cannot do anything) or because you requested a too low correction with DT properties.
Minimum required ECC for this device is 8-bit. Below is the datasheet for your reference.
