Currently on a imx6sx-sdb board, which has two SPI NOR chips connected to QSPI2 the following output from /proc/mtd is seen: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi" mtd1: 01000000 00010000 "21e4000.qspi" Attempts to partition them on the kernel command line result in both chips with identical (and identically named) partitions, which is an inconvenient behavior. Assign a different mtd->name for each mtd device to avoid this problem. After this change the output from /proc/mtd becomes: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi-0" mtd1: 01000000 00010000 "21e4000.qspi-1" In order to keep mtdparts compatibility keep the mtd->name unchanged when a single SPI NOR is present.
