From: Stefan Weil Date: Sun, 10 Apr 2011 16:23:39 +0000 (+0200) Subject: Replace cpu_physical_memory_rw were possible X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~6014 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=54f7b4a396d00522d99c685562a54725a1b52e40;p=sdk%2Femulator%2Fqemu.git Replace cpu_physical_memory_rw were possible Using cpu_physical_memory_read, cpu_physical_memory_write and ldub_phys improves readability and allows removing some type casts. lduw_phys and ldl_phys were not used because both require aligned addresses. Therefore it is not possible to simply replace existing calls by one of these functions.
