[PATCH v2 1/2] riscv: defconfig: enable spi nor on Hifive Unleashed A00

From: Sagar Shrikant Kadam
Date: Tue May 19 2020 - 06:46:52 EST


Enable MTD based SPI-NOR framework in order to use spi flash available
on HiFive Unleashed A00 board, and move SPI_SIFIVE to Kconfig.socs. The
configurability of SPI_SIFIVE is retained and still can be enabled or
disabled as required.
