Andreas' TC58NVG0S3H seems not to follow Toshibas/Kioxa's own datasheet. It only reports the first four bytes: "98 f1 80 15 00 00 00 00". This patch changes the id_len in the entry to 8. This makes it so that Andreas' NAND is still detected. At the same time, this prevents other Toshiba NAND flash chips - that share the same four bytes - from being misdetected. The issue has been reported upstream, since they also accepted the initial patch... so if not addressed, 5.19/5.20 will also break those affected devices again.

The Toshiba TC58NVG0S3HTA00 is detected with 64 byte OOB while the flash
|
|
has 128 bytes OOB. This adds a static NAND ID entry to correct this.
|
|
|
|
Tested on FRITZ!Box 7530 flashed with OpenWrt.
