Merge tag 'nand/for-7.1' into mtd/next (2026-04-17 21:51:05 +0200)
----------------------------------------------------------------
* MTD changes
mtdconcat finally makes it in, after several years of being merged and reverted.
Baikal SoC support is being removed, so MTD bits are being removed as well.
All the other changes are misc cleanups.
* NAND changes
The main changes happened in the SunXi driver in order to support new versions of the Allwinner NAND controller.
There are also some DT-binding improvements and cleanups.
Finally a couple of actual fixes (Realtek ECC and Winbond SPI NAND), aside with the usual load of misc changes.
* SPI NOR changes
There is only a collection of bugfixes this time around, with no notable changes to the core. Some of the more noteworthy bugfixes listed below.
- Enable die erase on MT35XU02GCBA. We knew this flash needed this fixup since 7f77c561e227 ("mtd: spi-nor: micron-st: add TODO for fixing mt35xu02gcba") but did not add it due to lack of hardware to test on.
- Fix locking on some Winbond w25q series flashes.
- Fix Auto Address Increment (AAI) writes on SST that flashes that start on odd address. The write enable latch needs to be set again after the single byte program.
