You need the patchset "mtd: spi-nor: add support for is25wp256 spi-nor
flash".

Thanks.  The patch also enables CONFIG_DEVTMPFS_MOUNT, but doesn't mention
it, so the following is what I've queued for v5.2-rc.  Let me know if you
object to it.



Apologies for forgetting about CONFIG_DEVTMPFS_MOUNT in the commit text. 
Thanks for the update.

Subject: [PATCH] RISC-V: defconfig: enable MMC & SPI for RISC-V

Currently, riscv upstream defconfig doesn't let you boot
through userspace if rootfs is on the SD card.

Let's enable MMC & SPI drivers as well so that one can boot
to the user space using default config in upstream kernel.

While here, enable automatic mounting of devtmpfs to simplify
kernel testing with minimal root filesystems. (pjw)

While we are doing this, can we add and test the /dev/mtd device?

I tried adding the following but I am missing something

CONFIG_MTD=y
CONFIG_MTD_OF_PARTS=y
CONFIG_MTD_BLKDEVS=y
CONFIG_MTD_BLOCK_RO=y
CONFIG_MTD_MAP_BANK_WIDTH_1=y
