hwstub/qeditor: add support for atomic read/writes 2014-11-18T22:30:44+00:00 Marcin Bukat marcin.bukat@gmail.com 2014-11-18T22:27:26+00:00 cd04a5f1aadc8e2ec4e787f5ba4cc8c38a579314 The current code assumed that READ/WRITE would produce atomic read/writes for 8/16/32-bit words, which in turned put assumption on the memcpy function. Since some memcpy implementation do not always guarantee such strong assumption, introduce two new operation READ/WRITE_ATOMIC which provide the necessary tools to do correct read and write to register in a single memory access.
