Name
kgdb8250_early_debug_ready — indicates when it safe to issue uart I/O
Synopsis
int kgdb8250_early_debug_ready ( | void); |
Description
This function should return 1 when it is safe to read and write to the uart. By default this is a weak alias which always returns true, unless overriden by an architecture or board specific implementation. This is overriden in case that uart I/O is only available some time after early kernel parameter processing.
