Some more details here as I also find that stable 5.4 is broken as
well 5.10 and 5.17:
The issue I see here is on a Gateworks imx6q-gw54xx board with a 2GiB
Cypress NAND part
[ 2.703324] nand: device found, Manufacturer ID: 0x01, Chip ID: 0xd5
[ 2.709815] nand: AMD/Spansion S34ML16G2
[ 2.713758] nand: 2048 MiB, SLC, erase size: 128 KiB, page size:
2048, OOB size: 128
[ 2.721990] Scanning device for bad blocks
[ 2.727025] Bad eraseblock 0 at 0x000000000000
[ 2.731628] Bad eraseblock 1 at 0x000000020000
[ 2.736191] Bad eraseblock 2 at 0x000000040000
...
The original regression was from commit d99e7feaed4c: ("mtd: rawnand:
gpmi: fix controller timings setting") which was fixed by commit
156427b3123c ("mtd: rawnand: gpmi: Fix setting busy timeout setting")
but later deemed to be an invalid fix so that got reverted (thus
breaking things again) and fixed instead with commit 0fddf9ad06fd
("mtd: rawnand: gpmi: Set WAIT_FOR_READY timeout based on
program/erase times") which did not make it into all the stable
branches that had the original commit or the revert of the potential
fix.
Here is history of each stable branch affected as best I can tell
(I've actually built/booted all of these trying to understand this so
fixed/broken refers to the issue I see above):
