From e24091398d50961ece2fcb2924d7c37d329abc09 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 4 Jul 2016 11:58:13 -0600 Subject: [PATCH] tiny-printf: Support assert() At present assert() is not supported with tiny-printf, so when DEBUG is enabled a build error is generated for each assert(). Add an __assert_fail() function to correct this. It prints a message and then hangs.
