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. - Paul From: Atish Patra <atish.pa...@wdc.com> Date: Tue, 25 Jun 2019 15:56:36 -0700 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.
