From 956a8bae537974673e126f67a227355f27e48ec6 Mon Sep 17 00:00:00 2001 From: Gregoire Gentil Date: Mon, 10 Nov 2014 11:04:10 -0800 Subject: [PATCH] ns16550.c: Fix for ns16550 driver hanging on OMAP4 The same problem that is seen on some OMAP3 is also seen on some OMAP4 so include them in the test in order to prevent some hangs during SPL.
