| Subject: tty: serial: earlycon dependency |
| |
| From: Tong Zhang <ztong0001@gmail.com> |
| |
| [ Upstream commit 0fb9342d06b0f667b915ba58bfefc030e534a218 ] |
| |
| parse_options() in drivers/tty/serial/earlycon.c calls uart_parse_earlycon |
| in drivers/tty/serial/serial_core.c therefore selecting SERIAL_EARLYCON |
| should automatically select SERIAL_CORE, otherwise will result in symbol |
| not found error during linking if SERIAL_CORE is not configured as builtin |
| |
