Linux' upstream MTD-Maintainer Miquèl Raynal noted: |Reverting seems the safest option here, not knowing how many devices |have these damaged/counterfeit chips. If it is just a couple and only on |Fritzboxes, as suggested in the Github issue this patch could be |carried through OpenWrt and that would seem more future proof IMHO. This patch follows up with the first patch. It actually moves the patches out of target/linux/generic/pending into the ipq40xx's patch heap and adds a little note what happend. For more information, discussions or reports about bad TC58NVG0S3Hs, please visit the OpenWrt's Github Issue #9962: <https://github.com/openwrt/openwrt/issues/9962> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

Subject: [PATCH] mtd: rawnand: add support for Toshiba TC58NVG0S3HTA00
|
|
NAND flash

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.
