Subject: [PATCH v6 1/5] RISC-V: Add stubs for sbi_console_putchar/getchar()
Date: Fri, 19 Jan 2024 17:04:45 +0530

The functions sbi_console_putchar() and sbi_console_getchar() are
not defined when CONFIG_RISCV_SBI_V01 is disabled so let us add
stub of these functions to avoid "#ifdef" on user side.
