When SERIAL_IMX_EARLYCON is enabled, and SERIAL_CORE is disabled,
Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for SERIAL_EARLYCON
Depends on [n]: TTY [=y] && HAS_IOMEM [=y] && SERIAL_CORE [=n]
Selected by [y]:
- SERIAL_IMX_EARLYCON [=y] && TTY [=y] && HAS_IOMEM [=y] && (ARCH_MXC [=y] || COMPILE_TEST [=n]) && OF [=y]
This is because SERIAL_IMX_EARLYCON selects SERIAL_EARLYCON,
without selecting SERIAL_CORE, despite that config option depending
on SERIAL_CORE.
