+lmbench: Can't proceed on some targets
+
+lmbench can't proceed on some targets. The memory check fails because the
+memory latency of each page is longer then 10us, which is a time limit set
+in the original memsize.c.
+
+The memory latency is very different on different targets due to the
+hardware and current system load. The targets with slower memory
+chips or heavy system load need much longer time to read or write
+the memory.
+
+This fix changes the fixed time limit of 10us to a specific value calculated
+from the runtime target.
+
+Also set an upper limit of memory size used for lmbench testing. The memory
+check sometimes fails if the target has a large amount of memory, for
+example more than 4G.
