* Name: riscv_earlyserialinit, riscv_serialinit, and up_putc
*
* Description:
* Stubs that may be needed. These stubs will be used if all UARTs are
* disabled. In that case, the logic in common/up_initialize() is not
* smart enough to know that there are not UARTs and will still expect
* these interfaces to be provided.
