Subject[PATCH] mtd: spi-nor: boya: add support for boya by25q128as
Date
Adds support for the Boya Microelectronics BY25Q128AS 128 Mbit flash.
I tested this on the Creality WB-01 embedded device which uses this,
although that was with OpenWrt which is still using 5.4 so I had to
do a bit of porting work. Don't see how that would make much of a
difference though.
