[U-Boot] Endless loop in cmd_log.c?

[Dennis Ruffer <daruffer@gmail.com>]

I am trying to implement CONFIG_LOGBUFFER and CONFIG_CMD_LOG on our ARM
systems and I seem to have run into an endless loop.  With loglevel=5 so we
still see our console output, the printf at the end of logbuff_printk
appears to create an endless loop.

I had to replace that line with serial_puts(msg);

Have I missed some other solution or do the systems that use this never set
logbuffer higher than default_message_loglevel?
