Attached are 2 bootlogs, v5.8 and v5.9. On the v5.8, I can see the QSPI devices under /dev/mtdX, and has this in the bootlog: [ 1.073562] cadence-qspi ff8d2000.spi: mt25qu02g (262144 Kbytes) [ 1.079865] 2 fixed-partitions partitions found on MTD device ff8d2000.spi.0 [ 1.086917] Creating 2 MTD partitions on "ff8d2000.spi.0": [ 1.092401] 0x000000000000-0x000003fe0000 : "Boot and fpga data" [ 1.103073] 0x000003fe0000-0x000010000000 : "Root Filesystem - JFFS2" In v5.9, I don't see the above output in the bootlog, and there are no /dev/mtdX. I did a bisect and it resulted in commit "a314f6367787ee mtd: spi-nor: Convert cadence-quadspi to use spi-mem framework". If I revert this patch, then QSPI device is under /dev/mtdX. There were no changes in the Stratix10 DTS files between v5.8 and v5.9 that should have any affect on QSPI. v5.9: [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] [ 0.000000] Linux version 5.9.0 (dinguyen@linux-builds1) (aarch64-linux-gnu-gcc (Linaro GCC 7.2-2017.11) 7.2.1 20171011, GNU ld (Linaro_Binutils-2017.11) 2.28.2.20170706) #34 SMP PREEMPT Fri Oct 30 13:44:04 CDT 2020 [ 0.000000] Machine model: SoCFPGA Stratix 10 SoCDK [ 0.000000] efi: UEFI not found.
