  spi: airoha: en7523: workaround flash damaging if UART_TXD was short
to GND (2025-11-18 20:07:41 +0100)

This pull request enhances NAND and SPI flash support, primarily
focusing on the Airoha EN7523 platform.
The Airoha SPI driver receives a major update, adding DMA,
dual/quad-wire modes, and a critical workaround to prevent
flash damage if the UART_TXD pin shorts to Ground.

New chips supported include FudanMicro FM25S01A SPI-NAND and several
Winbond SPI NOR devices. Fixes
include correcting Kconfig dependencies, updating the mtd benchmark
command to use lldiv(), and
addressing minor bugs in the generic spi-mem and SPL NAND code.

The patches pass the pipeline CI:
