fsl,legacy-bch-geometry was removed in kernel 5.4

[mohamed-ali_fod]

Hello,

The device tree property fsl,legacy-bch-geometry which was available in kernel 4.19 is no more present in kernel 5.4, could you please explain how to handle the legacy bch geometry in this case? because in kernel 5.4 the rootfs cannot be mounted form nand flash due to the following error: ubi0 error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB

Note: fsl,legacy-bch-geometry was the solution to fix ubi_io error in 4.19 kernel, below is the thread for reference:

Hi Igor,

I am aware about mentioned fix for 4.19 kernel but I am looking for fix of the 5.4 kernel?
