From bfb7d7a3d61ff23f9dd265a56e8b5cac5bbfd76e Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 6 Oct 2012 14:07:01 +0000 Subject: [PATCH] serial: Implement default_serial_puts() U-Boot contains a lot of duplicit implementations of serial_puts() call which just pipes single characters into the port in loop. Implement function that does this behavior into common code, so others can make easy use of it. This function is called default_serial_puts() and it's sole purpose is to call putc() in loop on the whole string passed to it.
