From f503b167b66007fc6b4434cd07a044ce4a56b6a0 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Fri, 24 Nov 2023 12:39:01 +0530 Subject: [PATCH] RISC-V: Add stubs for sbi_console_putchar/getchar() 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.
