Add support for slc-mode implemented in Linux for the Toshiba TC58TEG5DCLTA00 NAND and Hynix H27UCG8T2ETR NAND flash found on the NTC CHIP. This requires the addition of a paired-pages scheme, a new parameter for MTD partitions of slc-mode, and setting the correct paired-pages scheme for the TC58TEG5DCLTA00 and H27UCG8T2ETR flash chips.
Changes since V3:
- Rebased against master branch as of 2021-12-16.
- Added slc mode support for mtdparts command.
Changes since V2:
- Copied upstream Linux implementation of mtd_erase to fix an issue with creating new ubi partitions.
- Implemented paired page scheme and added support for Hynix flash chip. Based on a cursory reading of the datasheet it appears to use the same pairing scheme as the Toshiba chip.
Changes since V1:
- Updated mtd_read and mtd_write to match upstream Linux.
- Additional mtd_get_master to match upstream Linux.
- Removed notes about ubifs not working, because it is now.

Do you have any updated version for this or it is final itself?
Should be final, but I can rebase it again if need be. I've been running this successfully for the better part of about 3 months now with no more visible issues on my end. I never got fastboot to talk to the mtd subsystem the way I was hoping, but in the end was able to sidestep the issue with an swupdate based flash tool.
Please rebase and send.
I can confirm the patch series still applies, compiles and works on mainline master as of today, so no rebasing should be necessary. Let me know if you find issues on your end though.
Thank you.
Thanks, Jagan.
