Re: [PATCH v2 3/4] riscv: qemu: Implement is_flash_available() for MTD NOR

Currently, if MTD NOR is enabled then U-Boot tries to issue flash commands even when CFI flash DT node is not present. This causes access fault on RISC-V emulators or ISS which do not emulate CFI flash. To handle this issue, we implement is_flash_available() for qemu-riscv board which will return 1 only if CFI flash DT node is present.
