    console: Implement pre-console buffer · 9558b48a
    Graeme Russ authored
    Allow redirection of console output prior to console initialisation to a
    temporary buffer.
    
    To enable this functionality, the board (or arch) must define:
     - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
     - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
     - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)
    
    The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
    Any earlier characters are silently dropped.
