/****************************************************************************
* Name: syslog_initialize
*
* Description:
* One power up, the SYSLOG facility is non-existent or limited to very
* low-level output. This function is called later in the initialization
* sequence after full driver support has been initialized. It installs
* the configured SYSLOG drivers and enables full SYSLOGing capability.
*
* This function performs these basic operations:
*
* - Initialize the SYSLOG device
* - Call syslog_channel() to begin using that device.
*
* If CONFIG_ARCH_SYSLOG is selected, then the architecture-specifica
* logic will provide its own SYSLOG device initialize which must include
* as a minimum a call to syslog_channel() to use the device.
*
* Input Parameters:
* None
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure.
*
