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.
Thanks, Jagan.
