    generic: 5.15: Make support for BoHong bh25q128as generic
    
    Move the patch for BoHong bh25q128as out of ramips to make it
    generic. Not including 6.1.y since the mtd subsystem has changed,
    and does not need these changes.
    
    Patch was dropped with ramips updating to 6.1, hence we reintroudce it
    here for 5.15 generic.
    
    5.15.y functionality was verified on a Wavlink WL-WN586X3 Rev.a.

+Subject: [PATCH] mtd: spi-nor: Add support for BoHong bh25q128as
+
+Add MTD support for the BoHong bh25q128as SPI NOR chip.
+The chip has 16MB of total capacity, divided into a total of 256
+sectors, each 64KB sized. The chip also supports 4KB sectors.
+Additionally, it supports dual and quad read modes.
+
+Functionality was verified on an Tenbay WR1800K / MTK MT7621 board.
