Subject: ARM: pcm058: Match mainline Linux NAND ECC layout/behaviour
X-Git-Tag: v2021.10~234^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3da9630b8c4c7dc61090ef43b7be4aaadf7e735b;p=platform%2Fkernel%2Fu-boot.git

ARM: pcm058: Match mainline Linux NAND ECC layout/behaviour

Enabled "fsl,legacy-bch-geometry" in U-Boot device tree overlay
to match the legacy BCH geometry layout, which mainline Linux
applies when "fsl,use-minimum-ecc" is not specified in the device
tree.

Reinstated SYS_NAND_ONFI_DETECTION, which when disabled, masked
the mismatch on SOMs with Winbond NAND flash chips.
