From 7d3777d1069137800cdd1420a6c75cd94151d877 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 29 Dec 2014 14:26:50 +0200 Subject: [PATCH] OLPC: Use %*ph specifier instead of passing direct values The %*ph specifier allows to dump small buffers in hex format. Let's use it instead of passing direct values via stack.
